Basic functions of echo sounders. How does the sounder work, how is it adjusted?

Fishing is considered a popular form of recreation for wealthy people. This is not less a hobby, more active time spent, but also a good sport. Successful fishing requires mothers to develop new skills and knowledge, gradually cultivate new reservoirs, improve themselves and their equipment, and also take advantage of current possessions. Among the equipment most needed for fishing is a echo sounder. Another one is called a sonator.

Features of the echo sounder

The sounder is an indispensable accessory for beginners and experienced fishermen. It has several functions:

• identification of the bottom topography and underwater objects;
• I will investigate the water;
• znahodzhennya buying up fish;
• vimir glybini vodyami.

To understand how to use a sounder, it is necessary to understand the principle of its action. The device retrieves information about various objects by amplifying sound impulses. These, with their blackness, which are separated from objects, will ensure the supply of valuable information. Some expensive models are available and have additional capabilities. For example, they can easily identify the type of fish under water, indicate the temperature of the water, and so on.

Principles of setting up a sonator at chovny

Having chosen a suitable device, the fisherman must become familiar with the peculiarities of its functioning and its obvious advantages in order to be as confident as using a depth sounder. If the depth of the river or lake is small, then the frequency of vibration equal to 192 hertz is very important. Changes are narrow and are in the range of 20 to 24 degrees.

You can move forward even more accurately and completely, and the picture on the screen will be accurate and clear. Objects moved under the vessel can be seen from the right side of the annex. The depths of the bottom appear at its lower edge.

Experienced fishermen know that the images do not always indicate activity, since it shows information about any activities, and sometimes not in real time. The information contained in the left side was removed earlier, lower right-handed. So, having made a place for the zupina chovna, you will need to turn the little bits back.

Zastosuvannya I will attach from the shores

How do you use the echo sounder, having wandered around on the hard ground? Quite simply. For this purpose, add a special sonator, like a dartless scanner. Such a device is ideal for pumping water from the shore.

The device must be carefully attached to the hair and thrown into the water. Then, with full speed, control of your head is drawn, respectfully watching over the picture on the screen. The fragments on the projection will be visible only to those objects that were sunk into the cavity of the sonator, you will have to throw a shotgun several times. Then the droneless echo sounder will show you more information.

Features of a dartless device

The warehouse of such a device has only a monitor and a locator. This responsibility lies in the absence of connecting blocks to the cable. This robot is respected by the need for extra locality for the help of echolocation. The information captured by the block locator will be converted to the radio, and then will go to the central part of the annex.

At the head unit, the signals are transformed into a picture on the monitor. In this case, the warehouse elements of the sonator loom around the core of life. The dartless echo sounder has a completely sealed housing. It is provided with a manual fastening part for the cord or fishing hair, and also has positive buoyancy.

Sanator Garmin

At specialized sales centers you can find out the availability of a variety of manufacturers. One of the most well-known and verified manufacturers is Garmin.

The Garmin sounder has some remarkable advantages:

• the widest model range;
• significant price range;
• simple decoration;
• the reliability is enviable;
• guarantee efficiency;
• wonderful brilliance.

Models designed for winter fishing easily capture important information through thin ice, resulting in a larger catch. The device contains a special sensor that emits acoustic sounds. Under the water, the stench spreads onto the bariers, immediately turning back. The Garmin sounder reports fishing data about the fishing ground, the fishing season, the hour spent and the objects that were caught on the line.

Secrets of successful fishing

To successfully use the device, instructions are provided before the sounder. To maximize your strength, set your adjustments. For whom:

1. There is no need to be afraid to conduct experiments.
2. It is important to set the depth in particular, where the fishability will be transferred.
3. It is necessary to install image purification and noise reduction to get a better picture.
4. For color models, adjust the screen data.
5. You can detect a level of sensitivity. It is recommended to upgrade to 75 hundreds.

Since the fish-sounding sounder is subject to wear and tear in the winter, it is recommended to save a special box made of polystyrene or a warm bag. For this type of fishing, only two methods are relevant: freezing in ice or placing a sonator in a prepared hole. There are a lot of difficult things that can be done with them - either remove them from frozen water or use a new handy and reliable trimmer. Also, it is not necessary to rely on the control function for fish recognition. In the minds, the cold will not be very effective.

In this way, there are no special problems with nutrition, such as using a fish finder, not to blame. It is important to listen to their recommendations, learn how to use the equipment, and then you will help to achieve great catches.

REVEAL

Today, the installation of echo sounders has become an indispensable aid for fishing. Even with the help of these devices, fishermen can easily determine the peculiarities of the bottom topography, the presence of cramps, fish and water temperature.

Today, there are a variety of fish finders on the market, due to the particular popularity of the Humminbird company's devices.

I will adjust the first difficulties of operation and adjust it for myself. The instructions are often not Russified and it is not possible to give precise information on the expansion of power supply for newbies.

Having become familiar with our recommendations, fishermen will find a reliable fisherman, and not just “a game created by marketers to win pennies.” Even if you understand the peculiarities of operating the equipment and have adjusted it for yourself, fishing can achieve excellent results such as rich catches.

Great recommendations for nowrіytsі sonar Humminbird

• Virobnik produces a wide variety of series and models of echo sounders, which vary in technical characteristics. Obviously, a specific skin model will require careful adjustment to the approach in general. Download the Russian version of the instructions for your Humminbird fish finder.
• But experiments don’t need to be afraid of messing up. If this is not the case and the efficiency of the robotic sounder with the adjustments of the operator decreases, you can soon return to factory settings.
• This is due to the special nature of fishing. If fishing is carried out at a depth of 5-8 meters, it is necessary to monitor the water expanses at this location. Only with the help of manual adjustments can you achieve the most accurate result and clear image display.
• Adjusting the criteria for sensitivity is not a single correct indicator for all minds. Adjustment must be carried out during operation, starting at 75% and gradually adjusting, to find the optimal performance.
• Adjusting the color scheme - using the method of trial and error, the optimal display is selected, in which the image is as clear as possible.
• Noise suppression and image purification – data adjustment must be set to the lowest level. In this manner, the painter captures the clearest image.

As soon as fishing has added its first echo sounder, it immediately begins to worry about how to properly train it. If you supply food to a salesperson in a store, then you know that everything is adjusted automatically. That's right. When switched on for the first time in automatic mode, the optimal values ​​for the relief and the search for different functions will be installed. One of the most important shortcomings is that the depth is measured in feet, not meters, and after washing the fish identification mode is activated.

In order to change this, you need to go to the menu. As soon as you change anything, the sounder will remember it, so it will be updated when it is turned on. If you start fishing, then it is better to cancel the identification mode, the remaining parts of the wines will be richly intelligent, otherwise the completed fishing will be successful, as soon as you turn it on, the remaining parts of the wines will not be forever and informative.

Most often, you need to change the settings to brighten the image, so you know how to use the echo as much as possible. For this purpose, you can enable a rich screen view or increase the view of the image, move or change the sensitivity, expand the range of depths. After fishing, change the range of depths that are probed in order to determine the bottom topography for which it is necessary to expand. The wider the range, the more accurately the bottom surface is probed, all irregularities are revealed, and the depth is measured more accurately.

If you change the sensitivity of the device, the width of the exchange, which looks for fish, shortens. How can you adjust the sounder so that you can more accurately identify the market place? For which we change the range of exchange, more precisely, the precise relief and the significant place of fish, but not smut - do not overdo it, otherwise the sounder will not be able to produce not only small or medium-sized fish, but also large eczema plyari.

If you choose a fish finder for professional fishing, you need to select models with an expanded menu, the functions of which can be adjusted according to your discretion, and even then changed or increased sensitivity will be insufficient, if necessary. You can familiarize yourself with and adjust the high-speed sensor or adjust the diagram of the standard sensor.

Remember that before you use the sounder, you need to become familiar with all the functions, check that the settings are correct, and then proceed to operation. Before choosing a fish finder in the store, be aware of the fact that you know how hard you will probably get a simple model with automatic adjustments, and you may need an accessory that can be used by not only novices, but also professionals. іnalovi.

This part will have problems with the simplest nutrition associated with sounders, and for an easy understanding of what is written, I would like to recommend following the path “from practice to theory,” and not just like the classics. I hope that it is much more beautiful, since there will already be a clear practical evidence of the victorious sounder. To carry out a few fishing trips with a depth sounder, and then read the article, which, I hope, will clear up how everything is adjusted and how it works. After this, you can already be aware of playing with the adjustments or depriving everything of a calm soul.

So you better grab the sounder, ride around and marvel at what it shows. In principle, the “out of the factory” adjustment has already been installed completely optimally, so as to show the whole picture. We just get wet, we go, we marvel, after fishing we get wet. Or you can, of course, read the article, take a ride and read it again - it will definitely be even more beautiful. It’s just that if you don’t understand it, skip it, you’ll figure it out later. Metastatti speed up this hour.
So let's see.

Frequencies and exchanges

Frequency in this context refers to the number of pulses sent by the sensor per second. At the moment, finder detectors are most actively searching for the following frequencies and as a result of the exchange:

200 kHz

The highest frequency for 2D echo sounders. It works up to approximately 300 meters, produces a width of up to 60 degrees (with a high level of sensitivity in mind) for the clearest and clearest picture.

Here is a diagram of a 50 kHz exchange, but the principle is the same when miming to other exchanges -
200 and 83 kHz, just change in degrees depending on the frequency and
We chose sensitivity from the menu.

Tobto. The channel itself is narrow for a clear marking of the bottom, but if the sensitivity parameter is increased, it expands and, apparently, sinks more underwater objects, such as fish.

What is this needed for? It is clear that for the sake of searching, a wide range of fish is good, but good may be in the world. If the gap is too wide, we will get everything together after sleeping on the floor. A porridge with a mass of arcs or fish will appear on the screen, but you will understand that everything is even more important. That's not all. And one more nuance - if we change the bottom widely, we will experience serious inaccuracies between the displays on the screen and the actual bottom topography. Especially around the hour of walking along the shore of the coastal sanctuary.

For example, if the shore and the village are located, it is acceptable, on the starboard side, then the right edge of our wide edge “falls” on the upper edge of the beam, and the left one - down from the beam. glibini , which we really don’t have. We’re just going to the top of the coastal ridge as on the top diagram with changes. At the top of the ridge there will be, say, 2-3 meters, and at the bottom, let’s say, 7-8 and the sounder processor will be “straying around” for us show 2 or 5 or 8 m. Lowrance itself and having created such a “reasonable” promin.

So, a narrow passage is rather good, since it is important to us in advance of the exact topography of the bottom. Here's another analogy to make it easier to understand why. Find out what kind of landscape you need to paint. For whom you have a wide, generous penzel and a thin olive. Which is more beautiful, clearer and more accurate than tiny ones? I’ll repeat it again - it’s especially difficult to walk along a sharp bank break if one side of it is stuck on the upper part, and the other “falls” down. Please note that the new frequencies of 455 and 800 kHz and, obviously, are based on other principles and with a significant width, the accuracy of the image of the bottom and bottom structures is simply amazing. Ale about the price is lower.

If your sounder has a choice between 200, 83 and 50 frequencies, 200 kHz itself will be the main frequency for the majority of the catches on your fishing grounds. The other two will be of little help to special minds, as discussed below. It’s also important to note that three frequencies cannot be processed simultaneously in the echo sounder. If there are all three in the menu, run at least two at a time. In this case, when both echoes are turned on, it will automatically divide the screen into two windows. In one there will be images at one frequency, in another there will be another. What frequencies you want to be stored in the sensor and adjust the sonar menu. The "Marine" sensor can operate at 200 and 50 frequencies, while the primary sensor can operate at 200 and 83 frequencies. So, everything should lie under the sensor, and not under the “head”.

50 kHz

T This is the name of the “morska” frequency. It is crushed for pressing through thick sea water. It creates a water pressure of approximately 90 degrees, suitable for imaging the bottom at depths of up to 1500 meters. Why should we consider the wider one to be the forward frequency? Behind the logic, this has been developed to counteract the overwhelming power of the hitavit. In practice, when the frequency is turned on, the “clacking” from the sensor becomes rare rather than strong. In this manner, this passage penetrates deeper into the salt, filtering the water.

But I think you are unlikely to benefit from this frequency for sea fishing at depths of up to 100 meters. Vіn is wider than the classic 200 kHz. In this case, the width of the hole allows me to smooth out the confusion of the real depth after the pitching. So the wider sea is more beautiful than the bottom when the ship is rocking out to sea. Koli yogo vmikati? Then, if the 200 frequency can’t handle it. Doesn’t reach the bottom, apparently doesn’t show the bottom through deep water, goodness or fluidity.

83 kHz

A strikingly new frequency, subdivided for vikoristannya on the milky waters. Dribnovodya, in my understanding, is 6m and more. When switched on, the width increases to 120 degrees (with maximum sensitivity set). Apparently, the accumulation of the bottom becomes more than twice equal with a 200 kHz change. On one side it is better - there is more bottom coverage, on the other side the accuracy of marking the bottom decreases, especially when passing along the side of the coastal ravine, if one side is exposed to the upper edge of the edge, and the other – to the lower edge. It’s better not to interfere with the inclusion of this frequency without need. Turn on the sensor in other places – less than 4 meters. I don't want to give you a chance to fish the fish, so I should stay away. Shvidshe for everything is viplive z-pod chovna before that, how to waste in the zone of deeds in exchange. Insha river, if we catch catfish near the temple with quok or horse mackerel in the sea. Twice as wide as possible, for everything, allow the fishing tackle or fish not to sink into a thin cone of 200 kHz. And here there is a new sensation of trying and stagnating.

If you still need such a change in addition to the base 200 kHz, look for a model with the inscription Pro, based on the names of models of the same price level. Or check whether this is present on the older models without the word Pro. For example, i Elite.

Two new frequencies have been introduced for the new generation of DSI, HDI and LSS fish finders 455 and 800 kHz.

455 kHz

Allows further and deeper penetration of water, approximately 30 times the same frequency as 800. It’s too bad to give up. More precisely, the details of the bottom structures are thinly painted.

800 kHz

It is soon approaching the end of its daily exchanges and begins to “destroy” at a depth of over 18 meters with a significantly cloudy day. On the other hand, when there is a slight sound at high speed (obviously, not at significant depths), I would rather turn it on myself. Because, in such a way that the frequency of the pulse sent to the pulse greatly exceeds the value, the picture has a chance to appear more detailed, less 455 frequencies, without even seeming about the classics 200, 50, 83 kHz. In practice, it turns out that 455 kHz is still much more likely to stagnate and turn on 800 There are sensors only at depths less than 6 meters or for fine shading of the Downscanner (lower high-frequency exchange), and then up to a depth of 15 meters.

Now report on the possibilities of new frequencies (455-800).
Not only that, the frequency is two times higher, less classical, the frequency of 200 kHz is important for us, but also the one that operates at this frequency has a different shape, flat, looking like a lemon slice when cut out. If the animal marvels at the “flame” in front of me, then there will be a strongly splashing ellipse, perpendicular to the top, and not a round cone, like the light of the light in a classic 2D echo sounder.

Src="http://site/img/tmp/mark_elite_1.jpg" alt=" -form 200, 83 and 50 frequencies. -form 455 and 800 frequencies" width="484" height="375" align="default">!} !}
- form of 200-oh, 83-oh and 50-oh frequencies.
- form of 455 and 800 frequencies.

From one side, the narrow form changes the area where the fish are buried, if you stand inviolately or you vikoristovuet the sounder for skidding on the ice. If we exchange 455 or 800 kHz, we need to “walk” over the fish, and not abyssally, sideways, but at the same time changing the course, so that the thin sideways move evenly on the sides facing the surface.

On the other side This technology gives a dazzlingly vivid image of the underwater landscape and fish, among other things. It also shows a picture of what is visible directly from the bottom (50 cm above and below), which is practically impossible for a classic echo sounder with variable frequencies of 200, 50, 83 kHz.

Screenshot (screen copy) of one and the same place with different technologies - new 800 kHz and old 200 kHz.
Moreover, the classic (below) is equipped with the advanced Broadband technology for 2D echo sounders.

At the bottom behind the dumper there is a carp with a weight of approximately 7 to 15 kg. It is clearly seen that the primary sounder using the Broadband technology will reinforce the fish from the bottom.(picture below), at that hour, as the Downscanner (burns up) calmly paints, so that it’s still worthy to rise to the bottom. Moreover, on the dump itself there is some kind of third-party object, perhaps the bottom of the fish or the dump. Well, it is especially important that the bottom fish (pike perch, catfish) by their very nature tend to take a toll on themselves, or else not to themselves. On the other hand, a classic fish finder makes it easier to understand what the fish itself is, and its clear arc and subtle color.

In this screenshot, by the way, you can better see a group of silverfish using additional DSI technology (burning picture) at 455 kHz frequency. Note: sometimes the 2D echo sounder paints better, but the 2D sonar works better, and the scanner works slowly.

Well, and of course, the best option today for searching for the bottom structure is the integrated Lowrance HDS system. Such a system has everything that can be added and everything works, instantly seeing a new picture. І 2D sounder with Broadbend Sounder technology with frequencies 200, 50, 83 (along with the installed sensor) and new scanning technology and give the production range on all sides, even up to 80 meters on the skin side . So, in total, up to 160 meters of smudge cover will be covered with changes from the image intensity, aligned with the X-ray image, or refer to the photo. The underwater surveillance camera cannot be compared with such a system, since the visibility of the water does not have any significance for it. Before speaking, if necessary, the camera can be connected to new HDSs, which already have a video input. Sometimes the camera is needed for a detailed look at an object from a close distance, after it has been detected by the Structure Scanner. Most often it is much easier, faster and cheaper, and less likely to be used by the diver. After completing the following steps and using the following skills, the result on the screen will be something like this:

Upper great left upper square- Bichni exchanges. Zero - this is the trace.
At a distance of 20-40 meters, the right-hander along the side of the white carp appears at the sight of large points.
The beast's right-hander- Downscanner at a frequency of 455 kHz. There are black spots on the screen around the edge of the screen.
Right-handed below- stink on 2D sounders from Broadbensaunder.
And, you will find, there is a GPS map at the bottom, which you can accurately see and indicate the place of expansion
this is the result of any known cramps.

This is the top level of functionality and functionality today. And perhaps your first sounder will immediately be like this. Well, if we turn to the budget versions, for example, even further, in my opinion, the result can be seen as follows:

Playing the same fatheads. The brightness of the image is not really affected by the distant photo
camera, "real" images are more beautiful.

In practice everything is simpler

Mushu make you happy. On the water, everything will be much simpler, as it is written in the statistics, either to explain with the words “on your fingers” or to show in the demo mode. It would seem that the uneasy food would fall away by itself, as soon as you drink it and begin to crumble in the water. It is important to note that learning, as I have already said, is best carried out not from theory to practice, as is recommended by the classics of the theory of methodology, but instead. Then we take it from scratch and “blindly” test it, using intuition rather than knowledge. Then we have specific nutrition, further in the dzherel, or under the hour of discussion with the fakhivs, we look for variations on them. I’m starting to practice again, I’m starting to eat again, and I’m looking for evidence again. That’s better because you’ve been practicing with a sounder for quite some time and now you know, reading this article.

If you don’t understand especially, you won’t get embarrassed, I sing to you, after singing practice for a year, it will be simple and understandable. Just skip ahead and read further, and re-read here after 10-15 fishing trips.

Still, it’s time to understand the basics right away.

The principle of the robotic sounder – as briefly as possible

Nutrition is important, I recommend that you exert yourself and understand. This will help you to better understand your image. For Tim, everything is even simpler: like two twos.

Then, the vibration sensor emits audible clacking sounds (pulses) at the bottom.

The impulse on its way catches various objects and reaches the bottom and is knocked back up to the vibration sensor, which now receives it back. From the depth to the bottom and back, the impulse collected various information: the thickness, size and thickness of objects in the water and the bottom itself. The head, or rather the processor, processes the information collected by it and displays it on the display as a graphic image that collapses. It's like a cardiogram's heart.

And here we should take care of one very important point: regardless of the fluidity of the rudder of your boat, from further steps to maximum fluidity, the sonar screen scrolls through the picture with one and the same programmed speed Yu. And the koristuvach blames fair food: “We’re standing on the spot, and the picture is collapsing! How can that be?” Moreover, as soon as I exchange fish or tackle in the cone, there is a long dark cloud on the screen, and the cob-cob has a feeling of enmity that this is greater. In fact, the impulse rapidly jumps out of that very object, and the screen of its disturbances is constantly shown.

And now let’s assume that we will cover the same subject at a speed of 5 km/year. The impulse comes from our object (fish, crab, grass, mesh) more than a dozen times. And appear on the screen, swidden for everything, that’s the name of the arc and flame of singing size. And if we then pass an object with a speed of 20 - 50 km/year, then we will immediately hit the object a few times. And it will appear as a very small and short bow. Or maybe they are not able to figure it out, because the object is small and the liquidity is high. Moreover, in all three modes the screen scrolls with the same speed.

Walking along the river door with very low speed is 1-3 km/h. After the "attack" on the fish choven
she began to shout, and the right edge of the doorframe stretched even further.

And this fish itself was scanned at a normal speed of 5-7 km/year. Smugi (ribi) became short
And the figure is smaller than the size.

The basic idea is this: since in practice it was not possible to pass through the object with optimal speed, then I would like to correct the described phenomenon in order to correct for speed. 2D fish finders have an adjustment for “screen scrolling speed.” They can be adjusted in such a way that subjectively the movement of the earth above the bottom is avoided due to the fluidity of scrolling the screen. On DSI, LSS and HDI scanners, the speed of scrolling is adjusted daily. I don’t know how the picker got there, but in practice such hostility is created that they themselves want to make corrections for our fluidity in the economy and paint a picture as believable as possible (as far as possible), regardless of our flaws in management. Aries

How to use the echo sounder?

Almost regardless of model or brand – it’s really simple.
Turns on - rides and watches - switches on like fishing.

For the great reason, there is no need for them to fawn on the basic understanding of this word. The word vikoristati is coming. So, for the great reason, you have to do everything yourself, just keep it in mind and don’t forget to put it in at the end. It’s just how it was intended by the manufacturer and all standard settings from the factory are set to auto modes, which is generally normal for performing its function. At any rate, perhaps, you should first adjust it to your new fishing minds, this year. Further, you may need some minor correction no more than 1-2 times per river.

If you are using a fish finder-chartplotter, then the rule is “Vimk.-Vimk.” The same works, but it wouldn’t hurt to learn more “stuck” techniques. If we wanted to put things in order, then it’s all the same - having bought a TV, we connected everything, we started to click in and out, and we’re surprised at one program. I realized that I would really like to learn how to mix channels. These are great possibilities! Another way to understand what he shows. About the price below.

But still, due to such simplicity, there are a number of important, elementary rules that need to be followed. It is important to carefully survey the water area for the presence of fish and the bottom topography:

1. Shvidkist ruhu chovna is required within ranges of no less than 4 and no more than 10 km/year. And the maximum is 5-6 km/year. To ease the visual understanding, this is the fluidity of the human body. Thus, a simple structure can collapse under the influence of strong winds and flows. Rustling against the strong wind and current, there is an illusion of sufficient fluidity for the rustling rustle of water against the side of the chute. And suddenly, following the wind and the flow, you want to add gas. For the correct implementation of our instructions (a clear, truthful picture), a fluidity of 5-6 km/year should be in the bottom, and not in the water behind the water.

   By analogy, the correct calculation of the water area behind the additional echo sounder will be similar to the robot of a combine harvester. Level passages in one direction or the other, with a width of the width of the passage, without overflows and dullness on the spot. If you use a GPS sounder, the correctness of your passages can be seen on the screen along the track that you lost (trace) - another argument for the benefit of your addition. Since there is no chartplotter, but just a depth sounder, you can marvel at the wake trail. What appeared on the screen - this means that it was lost a couple of seconds ago (the hour of mixing and receiving the impulse and processing is approximately 1.5-3 seconds) and then you can approximately let it go, without fail. For all previous generations of Lowrance sonar chartplotters, you can simply hover the cursor directly on the sonar to find an object and use GPS to accurately calculate where it is. And give the opportunity to immediately put a waypoint in your place on the “Map” page.

2. For new generation fish finders with abbreviations DSI, HDI and StructureScan block respectfully avoid diagonal, “oblique” scanning. This is when under the influx of a strong galloping wind, the current flows almost like a skid. Then the exchange rate (course line) does not correspond to the real direct market. Choven walks sideways for a little while, and the picture becomes a little confusing. Therefore, the recommendation is simple - in such minds, scan either against the current or the wind and then across, placing the side.

It’s important to get familiar with the latest technology (especially HDS with the additional Structure Scanner block), or rather, hire a specialist who can conduct a training course. As far as I know, it is possible to fully learn how to use this technology in three years. If there is no such possibility, read the article with respect and try it out in practice.

How can you understand this?

Bottom

Everything is clear - this is a curved line at the bottom of the screen, and it conveys the visual relief. How can you judge the thickness of the soil based on the color of the bottom line? So, it’s really brutal. It might not be possible to notice a subtle difference in thickness from a mule to a turtle. No one will hire me. Ale Suttevu change, perhaps, can be significant. For example, the river bed (clean sand) has a remarkably thin bottom. We enter the muddy creek and the bottom becomes richly oily. However, there may be a significant difference in the thickness of the soil, to mark it.

And one particularity is important. There are places where the quantity of mula is simply incredible and the wine is even rarer than the standard semolina porridge. This occurs most often when water peas (chalima) grow in abundance. There, the echo sounder signal can simply appear, and it will lie under the brand, type of echo sounder or sensor. It’s just that the signal has nothing to fight for and it simply “goes out” in a deep rare mule.

What else should I wrap up? As I have already said, the delay when the signal passes from the sensor to the bottom and the sensor starts up takes approximately 1-2 seconds. That’s the number that was behind you 1-2 seconds ago. Make sure that when the depth number is displayed on the screen, you can already drive 10-20 meters at full speed until the display is removed. On the latest Lawrence models, connected to GPS with a depth sounder, you can easily calculate the location of the moving object that spills across the screen. Simply by pointing the cursor at the object that is marked on the fish finder screen, the carplotter will be able to accurately calculate your place of retrieval and allow you to put a dot on the map screen, indicating that you have gone from this place to the proper place. Get up.

Riba

On new fish finders with scanning technology, you can see spots or specks (depending on the size of the fish) of different shapes.

Above all, two screenshots of the echo sounder screen were taken, which simultaneously depict the same fish with different changes. All predictions and details will be displayed on the screen of the fish “with the little finger”.

How to understand, how to understand? Dosvid vikoristannya and rosuminya come approximately like this. You found out that you need a depth sounder for help, and you can probably fish or eat a bunch of grass. Next, let’s find out what kind of fish it is, so that we can find out in other fishermen what kind of fish they catch. In this manner, as you go, you now understand that this is how such a fish is portrayed. As soon as they pulled out a bunch of grass, it became clear that this is how the grass itself is represented, and not the cramp.

This is also the mode for recognizing fish and displaying them with fish symbols. In principle, the unprofessional handwriting of the inclusion of this mode is respected. And until recently, it was appreciated that this was a marketing move so that the corn-cobs would not put up complicated explanations: “What about fish?” However, technologies are still being improved, and in such cases it is better to turn on this function. For example, when it comes to fishing at the temple, fish (horse mackerel, for example) or from the ice. Moreover, please turn off the sound signal when a fish is detected. With such a simple glance, the fish modes of the fishing mode (from the fish symbols and sound signals) appear, it is even easy to fish for pelagic (the same as in the same waters) fish without looking at the screen. When we hear a sound signal, the fish is below us. If the signal disappears, the discovery has been replaced and the need to search for it again.

There are a few drops, if the fish cannot be seen in anything. For example, if all the fish (most often the young ones) “walk on top”, then they are 1-3 meters above the surface. Vaughn is simply running away in front of the choir. I think that as soon as the sounding systems develop, it will be possible to search for such situations with an echo sounder from the wind using unmanned aerial vehicles (UAVs). Underwater people are already aware of news from space.

Writhing, seaweed

The method of learning is the same as in a fight with a fish. As soon as they found it, they grabbed it, threw the tackle - zachip. They pulled the bait with a hook - that means cramp. They cut the tackle, the bottoms are on the bottom - that means metal or the concrete is overgrown with turtles.

The underwater Myslivians began to burn well. You can just smell it and wonder what’s really there.

The first adjustment, which is based on the “Russian language”, “metric system”, you can ask the seller to adjust or adjust independently.

For other adjustments, the recommendations are as follows:
For starters, most often from the plant everything is already properly adjusted. However, you can do some easy tuning. For 2D fish finders, increase the “pulse shaping frequency” to the maximum and increase the speed of scrolling the screen a little. Reshta, which is not clear, set it to “Auto” or as installed from the factory.

For DSI scanners, we change the contrast to 40%, select a black and white palette for the bottom layer and a light brown palette for the side. The most important frequency of drops for DSI is usually 800-a, for LSS scanners - 455-a. Rashta - on "Auto".

Chilling fish?

Chantly, everything lies down for a specific episode. What kind of fish, at what depth, is active - passive, in the cold or on open days, in what kind of fishing, in what geographical place, where is fish known from people? So, here at night, on a wild body of water, all the impulses of the echo sounder began to add new fish. And at the same time, that fish itself, in similar minds, but in the densely populated fishing area can become even more wary of the sound that it associates with the recent troublesome ups and downs. The main mode is recognizing fish and displaying them with fish symbols - for life. Moreover, the fish are pressed one by one about the problem, connected, for example, with any subject (especially important).

As if I have supplied food to one of the completed “quackers” - what does the catfish bark when it rises to the quok? What I have to say is, “I’m still either barking or not barking, just watch out for your approach on the desktop screen with a spluttering and wilting view, so that the thought of your shutdown doesn’t fall on your mind.”

And yet, all the same, the rumors and the same evidence, I’ll say that it doesn’t cry anymore and there’s no sense in it, because there’s no way to save the battery.

What will it be like to “light” the sensor outside the home? How can you “catch” fish?

There will be nothing. If you simply stop grasping the space in which you are working, there is nothing visible for the impulse, so you know the bottom. For whom the classic chevron sounder is definitely not suitable. I want to try to shy away steadily. There are models of echo sounders for lateral viewing, both budgetary and professional for sea trawl fishing. I haven’t heard any good news about budgetary ones, but industrial ones are incredibly expensive and suitable for stagnation in the sea for trawls.

The sounder consists of four main elements: transmission (transmission), receiver (sensor), transducer (transducer), and screen (display).

The transmission vibrates high-frequency pulses that occur at regular intervals of an hour. In modern sounders, frequencies of 50 and 200 kHz stagnate, while the frequency of 192 kHz increases. The sound signals, which are reversed, widen in water with a speed of about 1500 m/sec. and break up from the bottom, fish, algae, stones, etc. Small. 1 ). Echo signals that reach the receiver generate new electrical impulses, which are then transmitted to the converter and enter the display.

The converted probing results are displayed on the screen of the device in manual graphic or alphanumeric form.

Small 1. Principle of robotic sounder

The display shows the results of ultrasonic probing and the robotic device. For which there is a rare crystal monochrome or color screen and keyboard ( Small. 2 ).

The images on the screen of the underwater space under the ship appear as a result of the search for the fireplace (sometimes another name is used - scrolling). The main working rosette (shvidka) is vertical rosette. Kozhzniyatiyatyatyatye eholota names a signal is on the ecrani of the darkness of the darkness of vertical noise, the viddlya is vid Lіnії on Virinoi Glibini Op'kta, and the vіdobrazha. The vertical flange of the right-handed screen gives a precise (mitte) picture of the ship.

The image of the underwater space under the ship at the coordinates “depth – hour” is followed by additional (more than one) horizontal rosette, which moves the image to the left of the screen. Thus, on the left side of the screen there is a picture of what happened under the water at the hour of sounding at the front of the hour.

If the vessel is intact, then the bottom will appear in the form of horizontal dark spots, and the fish that are being eaten in the middle of the boiler will appear as an icon (there will be more about them later) that move to the left at the same time as the fire.

As the ship sinks, the bottom image changes accordingly until the depth changes. In this case, for the accuracy of the picture, the fluidity of the combustion is responsible for the fluidity of the ship's rover - for which, in most sounders, there is the possibility of regulation.

In connection with this method of capturing the image, it is necessary to understand that the picture that is on the screen has not passed the stage. So, the fish icon that appears on the screen does not mean those that are currently under the ship in the viper's exchange, but those that have been there at any time. In order to ensure that you are directly under the vessel at the moment of attention, on most models of fish finders, an additional window is created on the right edge of the screen, in which it is displayed without a horizontal opening.

Small 2. External appearance of the sonar display

Rework (transducer) echo sounder

The most important element is the echo sounder, which has a lot to do with its characteristics. It converts the energy of electrical high-frequency pulses into ultrasonic vibrations and, at the same time, reversely converts the broken ultrasonic signals into electrical signals.

There are a number of types of converters behind the method of converting electrical energy into sound, and only piezoelectric ones have taken root on small ships due to their small size.

The main element of the piezoelectric converter is a barium titanate crystal (crystals of other materials are sharpened) of a cylindrical shape with metal coatings applied to its surface. Such a crystal is placed in a metal or plastic case and filled with material to conduct sound better.

Small 3. Re-creation diagram

Under the influx of a changing electric field applied to the working surfaces of the crystal, spring oscillations begin to arise, as a result of which the crystal begins to quickly feel and expand, screaming out of the water.

Vibrations from the bottom or other underwater objects flowing onto the crystal cause the appearance of an alternating voltage on the working surfaces of the echo sounder.

It is accepted to take into account that it transforms and receives sound energy between the cone. In fact, the cone is only easier for developers to demonstrate the characteristics of vibration. The real diagram of the distribution has a richly pellet structure - the head pellet, which produces the main part of the energy, and a number of side pellets ( Small. 3 ).

See the re-creators

The re-creators who vikorist in the search engines are separated by the offensive signs:

behind data warehouse , how can you recreate

behind material , The building has been rebuilt in such a big way;

behind Number of exchanges ;

behind place installed recreate on the ship.

Tribute Warehouse

The main purpose of the conversion is to pick up signals about the depth of the objects. However, there are changes in which additional sensors are installed in the housings, which allow the temperature of the water and the fluidity of the vessel to be measured and transmitted to the display.

Material

Reworks are made from plastic or metal - brass or bronze.

Plastic hulls are often used on ships with metal or plastic hulls. Plastic rework, insertion of a wooden hull, may be crushed when the wood swells after the vessel is launched.

Metals are designed for installation on ships with plastic or wooden hulls. When a bronze converter is installed on a metal hull, an electrochemical reaction may occur, which destroys the vessel's hull and converter in place of its contact. Water temperature and fluidity sensors can be installed in converters with metal casings.

Number of exchanges

At such an hour, the desolation of the morbid became one and the same. Infectious stench is constantly emerging from the range of double-exchange sounder companies, and its price is equal to the prices of single-exchange sounders. Two exchanges are made for the presence of two frequencies – 50 and 200 kHz, which is why they are called dual-frequency. Such devices can be used either on one of two frequencies or on both at the same time.

This is also true of the exotic models of production from the Humminberd company, in which three or six exchanges are formed - to expand the area of ​​view in the first phase and to create a pseudo-trivimirous picture in the other.

Place of installation

There are three main ways to install the converter - from the inside of the hull ("in-hull"), on the transom and on the bottom ("Thru-hull").

Operating frequency of the echo sounder

The depth of detection of underwater objects and the accuracy of their separation, however, the intensity of variation depends on the frequency.

The echo sounders that were released earlier had either high frequencies (192 kHz in Lowrance and Eagle fish finders, 200 kHz in Garmin, Raymarine, etc.) or low frequencies - 50 kHz. Currently, due to the wide expansion of dual-frequency echo sounders, only two frequencies have been lost - 50 and 200 kHz, which allows you to use one crystal to operate at two frequencies at the same time.

The width of the vibration patterns is proportional to the frequency of the vibration - the higher the frequency of the vibration, the narrower the cone, and the greater the density of the new sound energy, and as a result - greater depth and beauty of the building. The detection of other objects, more detailed display on the screen.

When operating at low frequencies, the width of the cone is much wider and, consequently, the intensity of energy in the cone is less with all the residues that accumulate. On the other hand, a wider vibration diagram allows you to detect fish in a wider zone, below the hour of high-frequency operation.

The advent of dual-frequency sounders made it possible to combine the frequencies of the skin frequencies in one device and eliminated the need to deal with the problem of choosing a sounder with a wide or narrow range. Daily dual-frequency (double-frequency) sounds allow you to work with one of two obvious changes, as well as both at the same time.

Manufacturers of fishing sounders often produce a large number of models with different modifications. Thus, the Garmin company converts at a frequency of 200 kHz from the corners of the cone from 8 to 20 degrees, at a frequency of 50 kHz - from 45 degrees. The two-pronged echo chamber has a width of 15 and 45 degrees. Approximately the same figures can be seen in the transformation of other companies. It is important to note that the converters vibrate and supply all the echo sounders from a number of specialized companies.

Flowing in the middle of the rosesultrasonic hvils

Water, being the middle of the vast creation of ultrasonic winds, flows into the sounder robot, so knowledge of the peculiarities of the passage of water in the water will be used for effective vicorization.

The effectiveness of the sounder robot is influenced by the following broad powers of the middle:

- Extinguished energy sound waves near the water;

- The presence of vibrations sound sounds near the water.

Extinguished energy

The extinguishment of sound energy near the water consists of two storage areas - the extinguishing of the open space and the extinguishing of the wider middle.

The extinguishment of free space means abstractions from the widening of the middle, which lies only in the distance, weakening of sound energy.

With active sonar, if the sound passes through the same two doors, the free space is extinguished in proportion to the fourth degree of depth.

The extinction of the energy of sound horns in water is explained by the clay and dissipation of mineral and organic particles, microorganisms and wind bulbs that are found in the water.

Fresh cold water contributes the least amount of quenching - due to the low temperature it increases the strength and contains a minimum of organic matter. In fresh water, however, you can use sounders with both low and high frequencies with success.

Salty sea water, however, contains a large amount of salts, plankton and mineral particles, especially in the well-warmed upper balls of the sea, which fade and dissipate the energy of sound sounds. Significantly weakening the energy in the salty water comes from the wind bulbs that are located in it, which disappear when the wind winds are closed.

The presence of vibrations

The differences in any medium - in the water, in the wind - are created by inhomogeneities that account for the thickness of the medium. They can be any objects (stones, soil, fish, vegetation, windy bulbs), or balls of water with different temperatures (the so-called thermoclines, as they are described later). Deep bodies of water may have a few thermoclines.

While in fresh water the extinguishing of sound energy at different frequencies is practically the same, in sea water the extinguishing and extinguishing of thermo-clines increases as the frequency increases. Therefore, in echo sounders used for searching for fish in the sea, the frequency is 50 kHz, and in some professional fish finders for deep waters, the frequency is 28 kHz.

Vibrant power of the bottom

The bottom of freshwater waters and seas has a heterogeneous structure, which includes variously thick soils - mule, sand, clay, stone slabs, pebbles, covered, as a rule, with various types of vegetation. All types of soils may have varying degrees of impact and sound absorption. Stones and clay are good at knocking out the sounds that appear on the screen in a wide line. Soft soils - mule and sand, as well as the growth of foliage, vibrate the needles, creating a thin line on the screen. At the same time, soft soils are permeable to ultrasound, so on the echo sounder screen you can see large surfaces underneath them that are underneath.

Vpliv roztashuvannya reworking

Converted by installing in the middle of the body

"In-hull" reversals are attached directly to the inside of the ship's hull. Stinks only occur on ships with hulls and skewed plastic. This type is not suitable for vessels with metal and wooden hulls, as well as those with multi-spherical slab-plastic hulls and porous linings.

The “In-Hull” redesign requires fastening to the plastic sheathing using epoxy glue. The use of plastic sealants for fastening is unacceptable due to their poor acoustic conductivity. They must be installed in such a way that there is water between them and the casing of the hull without any reinforcement or buoyancy-propelling inserts.

When the In-hull switch is reversed, the sound pipes pass through the plastic casing of the body, wasting some of the energy, resulting in a decrease in the maximum depth and the possibility of detecting fish.

Conversion from installation on the transom

Transformation of this type ( Small. 4 .) vikoryst, as a rule, on small, slow-moving ships.

Small 4. Conversion from installation on the transom

This type of conversion is installed on a special bracket located on the transom below the water level. The design of the bracket allows the transom to be reversed when hitting any crossing, thereby avoiding the well-established transom.

The advantages of such an installation are ease of installation, dismantling and maintenance.

Not enough - a search for propeller propellers, the wrapping of which leads to the formation of water, which reduces the efficiency of the rework. While at low speeds you can still find a suitable place on the transom, then on large and fast ships, propellers that operate at high speeds create very stormy water, pump the water into bubbles in the air, which is how the screen changes, it is practical including the ability of robots.

Transformation from installation on the body (“Truehull”)

Converted to the “True Hull” type, which are installed on the body ( Small. 5 ) is inserted into the opening at the bottom of the vessel.

Small 5. Conversion from installation on the housing

This type of converter has the best characteristics, and also the highest price. They are suitable for installation on large and Swedish vessels with outboard and stationary engines. Place it on the flat part of the bottom in front of the propellers in places with smooth flowing water. If the vessel has V-like contours, then for horizontal expansion of the vicor, special plastic gaskets are used, which at high fluidity can lead to the appearance of cavitation and, apparently, a decrease in the efficiency of the echo sounder (about cavitation) Itation - div. below). To improve the flow of the air pump, special purifiers are designed to reduce turbulence and cavitation.

The advantage of such a conversion is high efficiency and signal strength.

The downside is the complexity of installation and maintenance, the need for regular cleaning to prevent the build-up of algae.

Pour of fluidity into the work of the re-creator

For many years, fishermen, professionals and amateurs have not had to deal with the everyday problems associated with the use of echo sounders on their vessels - the speed of these and others is small. In addition to the increase in speed, the owners of echo sounders began to notice problems with the robot fish finders - the loss of signals, the appearance of noise transitions on the screen, and the weakening of broken signals.

The main source of such defects is cavitation - disruption of the continuity of the flow line. When a properly constructed vessel floats near the water, its underwater part flows smoothly around it. There are various protruding parts on the body - the flange of the intake or exhaust pipe, rivets, bolt heads, etc., when turbulence begins to develop around them, the flow becomes turbulent, and when reached, some critical fluidity and the crazy cavitation bulbs begin to vibrate on the surface, which then pass from Caverns Due to the low intensity of the gas that fills them, the bulbs produce sound sounds and often mask the space under the vessel.

The most powerful converters that are installed on the transom: not only are they the source of cavitation, but they also remove all the bumps that have formed on the hull of the vessel. But the main gear for the transom switch is a high-speed propeller propeller.

In the shortest possible way, the re-creation of “In Hull” and “True Hull”, when properly positioned, is placed in places with smooth wrappings. When installing the True Hull converter on high-speed vessels, its operating surface, in order to prevent the formation of new cavitation, must not protrude from the hull, nor must it become damaged.

Sounder sensitivity

The concept of “sensitivity” characterizes the sonar’s ability to see weak signals and the fatigue of acoustic transients and reception noise. The magnitude of sensitivity indicates the ability to detect small objects in great depths.

The echo sounder operates in a very wide range of voltages - even the strength of the actuated signals that are received is proportional to the fourth stage of depth. Therefore, it is up to you to better receive weak signals from other objects, both at maximum depths and at extremely small ones.

The need for robots to operate in such a wide range of equal signals leads to a song of super-eternity in the choice of sensitivity. On the one hand, high sensitivity allows you to extract a large amount of information about various objects at extremely large depths, and, at the same time, at small depths such a sounder will accept signals posture head exchange barrel pellets diagrams directness and recreate it.

To reduce this sensitivity in echo sounders, you need to regulate sensitivity, which in the recent past was done manually. In modern echo sounders, in addition to manual regulation, it is more automatic.

Automatic control sets the sensitivity to the level of bottom movement so that the bottom indicator appears on the screen. The sensitivity change occurs automatically in response to changes in water depth and water level. The automatic mode will ensure normal operation of the sonar in almost all situations, which is important and important. If necessary, this mode may be switched off and adjustments will have to be made manually.

Installed sounder

Once we have become familiar with the principle of operation, the structure and characteristics of fish finders, we can move on to the next part – learning the basics of their operation. The fragments of different finders are fragmented one after another, based on an extended model, for example, from a series of Garmin echo sounders.

In this section, we will look at the methods of installing transformations and splicing methods with a sounder in the robotic process.

Installation of viprominyuvach

Correctly installing the switch is key to ensuring efficient operation of the sounder. Do not install behind rivets, ribs, water intake openings or other irregularities on the bottom, which can create turbidity in the cracked bulbs and create turbulence in the water. It is very important that you practice in a calm flow of water, otherwise you may be able to drink seriously.

Installing the transom hatch

The transom transom is supplied with a special bracket for mounting to the transom. The bracket contains a spring element that allows the vehicle to swing back when hitting any crossing.

The basic principles of installation of the reversal shown on Small 6.

Small 6. The principle of installing the rewind on the transom

Installation of the “In Hull” reversal at the building

On skewed plastic vessels, for ease of operation, a reversible valve can be installed near the hull. Some companies produce special fittings for this purpose, and with this very success, a basic transom converter can be installed in the middle of the hull. On many plastic small vessels there is a specially prepared place for installing the converter.

Often, plastic cases have weak reinforcement elements or porosity in their structure, which is susceptible to widespread ultrasound, so first glue the bottom and turn the whole place in this way. Pour a small amount of water into the hold, in the place of the transferred installation, lower the working surface of the converter into it and turn the image of the underwater space on the screen. Compare the depth values ​​with the real ones. Since there is no difference, you can safely glue the creation in place.

Installation of the True Hull converter into the case True Hull converters are installed at the holes in the bottom of the vessel. The outer and inner surfaces of the opening body are covered with a ball of sealant, the cable and the cable are inserted into the opening and secured through a washer with a nut.

The reworking screws are attached horizontally in front of the screw, with a keel and some protrusions, which may be the reason for the creation of the wind bulbs. Once the top of the bottom has been removed, you need to install additional gaskets to level it. For great bronze reworkings, special trimmers are produced ( Small. 7 ).

Reproduced information

The current sounding sounder can be captured and displayed a wide variety of information about the water bodies and objects located in it. Below are those that can be viewed on the display screen ( Small. 8 ).

Small 8. Image on the sonar screen

Sonar control

The sonar control is performed using several buttons and on-screen menus ( Small. 9 ).

Small 9. Sounder controls

Small 10. Panel and information on the screen

At the top left corner of the screen ( Small 10) You can view the control panel and a variety of information, including the level of power supply voltage, water temperature and moisture level (as indicated by the corresponding sensors). On the right side of the screen there is a depth scale bar and the “Promin” function. Alarm symbols and system notifications are displayed below the bottom images.

Now we are familiar with the main screen options, which also include the use of a robotic sounder.

Glibin scale (Range)

Glibin scale ( Small eleven) is necessary for installing and viewing the singing plots of the water on the screen. The setting is controlled by the cursor on the depth menu, which opens on the left side of the screen. Moreover, the device can automatically select a scale that indicates the depths under the ship at a time and change them according to the ship's movement - for which it is enough to place the depth scale cursor on "Auto" and press "Enter".

Small eleven. Menu panel

Zoom

The “Zoom” function is used to select the zoom level of the surrounding plots to zoom in on the screen. The Zoom function allows you to zoom in on all objects within the selected depth range. The scale value is set in the menu that opens. After installation, the screen is divided into two parts, on one of which there is a full-scale view, and in the other, the part is selected at the installed scale ( Small. 12 ).

Strength, sensitivity (Gain)

Previously, there was talk about the influx of sensitivity on the effectiveness of the echo sounder robot. High sensitivity allows you to pick out a large number of details, but you can also cause noise to appear on the backlit screen and to the appearance of objects moved around the side of the vessel with barrel pins. Therefore, all devices have organs. ї regulation. For which device sensitivity is set using the arrows in the GAIN window ( Small.13 ).

Small 13.

After washing in the sounder, a normal level of sensitivity is established, which is indicated by the Normal Gain position on the scale on the left side of the screen. If you need to pick out more details, increase sensitivity by selecting a positive adjustment value on the scale; if you need to change sensitivity, select a negative value.

The customization menu can also be customized for the sounder, so that it does not require frequent adjustments. This includes settings “Image” (Chart), “Tools” (Tools), “Numbers” (Numbers), “Alarm”, “System settings” (System), “Calibr”, “Calibration Units” (Units) and “Memory Management”, “Fish Symbols”. Since the sounder is dual-frequency, the menu will display another frequency setting. Let's take a look at their actions.

Chart

This setting adjusts the speed of scrolling and the speed of updating information on the screen. This works with the additional Scroll Speed ​​function, which allows you to select one of three speeds – Fast, Medium and Slow, depending on your preferences.

Frequency

This menu item is intended for selecting the broadcast frequency – high frequency 200 kHz (set after washing), low frequency 50 kHz, or both at the same time.

FishSymbols

This setting allows you to choose to display underwater objects in the form of fish symbols or in the form of broken signals (arcs). The choice is made in the menu with fish symbols and the “Off” position - turn it on. At this position, all received signals are displayed on the sounder screen. When you select any symbol, when any object is detected, the fish symbol will be displayed on the screen. If the sounder is used in dual-frequency mode, then fish passed through a narrow band will be black, and those passed through a wide band will be white.

Whiteline

The Whiteline function allows you to determine the structure of the rock balls to form the bottom. If, when the function is turned off, the bottom is displayed in a black color, then when this function is turned on, the bottom is drawn up to the thickness of the balls in shades of black and gray colors.

Tools

The Tools function has several tool sets—Depth Line, Flasher, Simulator, and Noise Reject—to help recognize underwater objects.

The Depth Line tool is used to determine the depth to an object or view. Represents a horizontal line lined with arrow buttons. The position of the line on the depth axis of the digital form is displayed in the information window on the screen.

Activating the "Flasher" tool creates images on a vertical smoothie. This tool allows you to more clearly display the details of the water surface of the bottom on the screen.

The Noise Reject function allows you to remove unwanted interruptions from the screen. The noise reduction mode can be set automatically or manually. Remember that at high levels of strangulation, some small objects may be lost.

You can use the Simulator tool to learn the sounder and get started working with it.

Alarm about the detection of fish (Alarm)

The sounder can give sound signals when fish are detected. The alarm can be set to detect fish of different sizes (small, medium, large in different variants). The alarm will operate independently of the enhanced Fish Symbols function.

This sounder can also generate alarm signals when the depth changes, which is less than a predetermined value, or when it is overextended.

Image on the sonar screen

For the sounder robot, it is very important to understand that we can actually read on the screen and not read much more than we can date. To get in touch with everyone, we can guess where we started our acquaintance with echolocation - the method of its promotion and reception.

As briefly stated in the section “Devices and characteristics of echo sounders,” the echo sounder produces sound noises near the bottom. The area that is covered by the vibrations is mentally described by a cone with the apex of the vibration and lies in the size of the depths and waters. Small picture 5 shows the intersection of cones with flatnesses at different depths for transformations with a frequency of 50 kHz and a cone cut of 20°, and a frequency of 200 kHz and a cone cut of 10°. If such transformations are applied, the surfaces of the coating at a depth of 9 m will appear to have a similar diameter of 6 and 1.8 m.

For the fisherman, it is very important to understand that, in accordance with the principle of action, the sounder only vibrates one coordinate - depth, and therefore we cannot give a spacious picture of the expanse of water in the cone of vibration ( Small. 14 ). It is impossible to tell whether there are fish or seaweed between the cones, but it is only possible to tell that they are located in the same depth. It is especially important to remember this when vikoristannі transformations with wide diagrams of directness.

Small 14.

Designed for bottom type with echo sounder

The sounder can recognize the type of bottom underneath it - hard ground, shallow water, algae. Hard rocks are better at beating sound needles, lower soft mules and sand. The ball of a hard bottom will appear on the screen as a wide, dark, soft bottom.

To improve the recognition of strong and weak signals in echo sounders, the main White Line function is “White Line” (a number of vikorists use the term “gray line”). When this function is enabled, the bottom is displayed in shades of black and gray colors. For example, a mule on the bottom gives a weak beating signal, which is displayed on the screen with a thin gray border, and images of a hard bottom are displayed with a wide gray border.

The “White Line” function allows you to determine the structure of the balls of the rocks to create the bottom. Obtaining information about the equal thickness of these balls, you can more accurately determine their structure.

Viznachennaya ribe fish finder

When the switch is correctly installed and the sounder is properly adjusted, the fish will be displayed on the screen in the form of arcs. Such images appear through the change of the riser until the fish passes through the vibration cone within an hour. When moving the boundary of the cone, stand in front of it until the rotation is at its maximum.

As you approach the cone axis, the view changes and appears on the screen. As the axis passes, the edges become larger, resulting in an image of an arc appearing on the screen that is collapsing.

The size and curvature of the arc lie below the width of the diagrams of the straightness of the transformation. The wider the cone is, the more pronounced the arc is.

When the fish enters the cone, the image will be thin due to the loosening of the tension at the edges. When it is close to the center, the thickness of the arc will increase and in the center of the diagram it will become greatest. When the fish leaves the zone of propagation, the picture changes in the reverse order - it changes.

If the fish passes along the edge of the cone, then the arc may not form, otherwise it will be small. The presence of the Fish Symbols function in sonars allows you to display received signals as symbols - “fish” of different sizes. This function can be used only after an hour of operation of the sounder in automatic mode. When the function is turned on, Fish Symbols no longer displays symbols and does not display the same other icons.

A number of models of echo sounders may be able to connect environmental sensors. And here the stench can be detected as fish under the ship, and on both sides of the boat.

Fishing sounder

The fisher is looking for fish, and this is its main purpose. However, most literate fishermen know that fish are not distributed evenly across the water, but are collected in places that are indicated by the bottom topography, sudden changes in depth and also by temperature changes between the balls. drive Of interest may be cramps, stones, yams, and growth. Otherwise, it seems, the fish is searching, where it is deeper, and where it is more beautiful to spend the night, lurk, masquerade, and yearn. Therefore, the first depth of the echo sounder is the value of the water and the depth of the bottom topography.

The results of depth measurement on the sonar screen are displayed in two ways - in a graphic form (displaying the bottom topography on the depth scale) and in a digital form on the screen. It is important to note that when using robotic sounder at extremely shallow depths, problems with vibrations may arise, primarily due to the presence of any “dead zone” in the echo sounder, as well as the presence of strong object detection and plots of the bottom, What is the posture of a cone of prominence, filled with barrel pellets and diagras? Such errors are especially noticeable in echo sounders, which do not allow for automatic power regulation.

Image of the bottom topography

When you change the depth along the right edge of the screen, a dot appears at the same time as the depth value you adjusted. To ensure the possibility of monitoring the relief, this point is saved on the screen and the right hand is moved to the left one step, and a new point takes its place, which resembles the depth of the depth. Then the onset of pain is detected - this is how the skin of the onset is remembered at intervals of an hour, equal to the period of passage of the probing ultrasonic pulses. The result appears on the screen as a line that shows the bottom topography. It is especially important to note that the drawn line reflects the relief on the road that the vessel has already passed, which should be taken into account when choosing a fishing position.

It is also important that the exact depth below the vessel is displayed on the scale on the right side of the screen. This value is repeated on the screen and in digital form.

If the ship is intact, then the depth under it does not change and, therefore, the line will be straight and horizontal ( Small. 15 ).

When the vessel is floating over an uneven bottom, the depth icon in the right corner of the screen changes its position until the depth under the sounder sensor changes. With a changed depth of the skin, the point of expansion will be higher than the anterior one, with greater depth - lower than the anterior one. As a result, a line appears on the screen that repeats the bottom topography according to the vessel’s depth.

For fishing, the greatest interest is in the various heterogeneities of the bottom topography, since fish are most often caught on them. These may include “mows” that are washed by the current from the inner side at the turn of the river, as well as sharp transitions on the outer banks that are under the influence of the current. With such sharp transitions, fishing is at fault, because there may be a lot of fish on them.

On the lakes of Karelia and the White Sea there are often underwater rocks of various sizes - small “men and corgis”, and large pebble or rocky “banks” - a favorite place for the great fish. It’s no wonder that professional fishing at sea is carried out mainly in cans. The author of these series somehow had the opportunity to catch a bucket of cod on the bare shells of the White Sea in the company of two friends for 20 hulls.

Another item for fishing is tse yami, in which there is a large fish hut.

In the meantime, any sudden changes in water allow fish to be caught and allowed to follow their findings in these plots. In the meantime, I’ll search with the sounder’s vicors to find the plots that appear against the important topography of the bottom. On small plots it is necessary to make traps with tai yami, on deep plots - combs, scythes, luds, tumbles, on cut plots - plain maidans.

Another important indicator that allows you to determine the prospects of this or any other plot for fishing is the structure of the bottom. The structure of the bottom refers to the types of soils the bottom is formed from - clay, sand, sand, rocks and pebbles. Using a sounder, it is impossible to accurately recognize the type of soil; you can only separate it based on its thickness. On the sounder screen, hard soil (clay, stone) is displayed in a light tone, and soft soil is shown in a dark tone. Based on the evidence of mule and growth, one can judge what kind of fish can be on this market.

Of great interest for fishing are the cramps and sunken trees of trees, from which fish can be found with a high degree of reliability. The smells are noticeable due to the thickness of the soil and are therefore clearly visible on the sounder screen ( Small. 16 ). Such objects must be completely memorized in the memory of the GPS receiver, so that their re-detection can be done in a rich way, either by cutting or rolling. There is also concern about other apparently small-sized objects - pits, pits, etc.

Variety of fish

Previously, it was understood that on the sonar screen the fish is displayed in the form of arcs. This is done through those that when the fish passes through the cone, it is forced to stand in front of it until it changes, it changes at first, and then increases again. As the fragments in the world move away from the axis of directness, the transformative energy produced changes, then when a fish passes through the zone that will tip over, the strength of the arc changes - initially it will increase , then changes again. The size of the arc lies, first of all, according to the width of the cone and the width of the cone - the wider the cone, the longer the arc ( Small. 17 ), and guide the fish to the vessel. The greater the strength, the weaker and paler the arc. Therefore, when you hear a fish from a boat on the move, showing faint arcs on the screen, you will turn around and walk through the place at low speed.

The shape of the arc can be infused with the characteristic patterns of fish, allowing, obviously, with some certainty, to indicate the type of fish, although not all fishing evidence matches this point of view. It is possible that some theoretical and experimental work was carried out on the recognition of fish species from various fisheries for commercial fishing, but such materials were not collected. The same thing is revealed and recognized by a professional and an amateur fisherman of all kinds.

Small17 . The principle of the creation of the arc

In some models of fish finders with a color screen (for example, in Garmin fish finders), the signals are displayed in different colors depending on the level of their intensity. The darkest colors indicate the strongest signals, the orange colors indicate the strongest signals, the yellow colors indicate the middle signals, the green colors indicate weak signals, and the blue colors indicate the weakest signals. In monochrome versions of the same sounders, the signals that are received are indicated by shades of gray color - the stronger the signals, the darker the icon, and so on.

Usual evidence in the press materials from the identification of fish and the results of the experimentation of core echo sounders, such assumptions can be made.

Many people see the pike as being displaced at one end of the same arc, the catfish as the same arc. Several types of fish are displayed on the sonar screen in the form of many thin arcs - for example, pike perch and fish. However, in the absence of any experimental data, the reliability of these estimates is low.

Since it is impossible to unambiguously identify fish, then to increase the reliability of the assessment it is necessary to immediately draw an arc with the relief and structure of the bottom, characteristic of the habitat of these and other species of fish. Such a robot will require a great deal of work with a depth sounder, an understanding of the characteristic features, the pattern and pattern of different fish.

To facilitate identification and recognition for fishing with little evidence, most amateur echo sounders have a function of displaying the detected fish in the form of symbols - “fish” of different sizes. The smells are formed by analyzing the algorithms for the strength of signals generated from underwater objects. Most fish finders have three gradations of sizes - small, medium and large, which are indicated by corresponding symbols.

However, it should be noted that by turning on the automatic recognition mode, you can receive reliable information about the size of the fish from the fish finder - the machine, the wine and the machine, vibrates according to the level of intensity of the signal and symbols for setting dimensions. The level of intensity of the detected signals depends on the importance of factors - the stage of water obstruction, the presence of plankton in it, the presence of algae, temperature changes, which the sounder does not fail when analyzing signals, so when they are struggling. In addition, the device does not distinguish all the subtle nuances of the received signals, which are easily recognized by the human eye, so you can assign symbols to fish, driftwood, and algae that drift near the water.

Symbols in monochrome echo sounders are barred in black colors. In double fish finders, the symbols of fish, taken with a narrow band, will be filled, and those taken with a wide band will be marked as contours ( Small. 18 ).

Another problem with automatic recognition lies in the impossibility of assigning the size of fish, which is indicated by the largest symbol - either a kilogram perch or several tens of kilograms can be assigned.

To identify large specimens of fish, some modern echo sounders have a real scanning function. Devices equipped with this function display an image of the fish on the screen, proportional to its actual size. Using the glybin scale, you can easily determine the size of the fish.

To complete our discussion on the topic of automatic recognition of traces, it should be noted that the closest device for which is still the human eye and brain - it is not without reason that professional fish finders display on the screen less than the display of real signals.

Scaling

Scaling is a very effective method of keeping an eye on the fish. The importance of scaling lies in the larger (stretched) surrounding views along the depth of the plots at several times, perhaps twice and even more times. For this operation, fish finders have the “ZOOM” function. The picture with a different scale can be viewed on the full screen, as well as in the split-screen mode, when on one half of the screen there will be a full-scale image, and on the other half, the area will be doubled or quadrupled image ( Small. 19 ), which is very handy for looking at the place - covered with vegetation, cramps, pits.

Small 19.

In fish finders there is another useful function that can also be added to automatic recognition - the “Alarm” function, which allows you to give sound signals when something is too far away from the installation of signals. Such actions can be:

- an image of a fish of small size appears on the screen;

- when entering an area with too little clay, or too much;

Exit from a given range of depths (“Drift”).

For a better display of the triggered signals, some models of fish finders have a pause function (“Pause mode”). In this mode, the cursor arrow is activated, which allows you to move around the picture that is closed, and indicate road points (such as before connecting the GPS receiver), as well as the depth and coordinates of the marks marked by the cursor in the view broken signals. The pause function eases the sound of objects such as fire, stones, and cramps, which may appear brown when choosing a fishing spot.

While the display is in pause mode, the unit continues to update depth displays; new data cannot be shown on the screen until this mode is turned off.
