How to choose the right echo sounders for winter fishing

Echos for winter fishing have recently become a mandatory attribute of this type of recreation. With the help of this device, you can easily determine the depth of the pond and the presence of fish in it, and you can very accurately know the size of the fish and the place where it is. The principle by which the fishponders work for winter fishing is not new and is based on the reflection of the signal that is sent and then received by the indicated device. All the results that the echo sounder receives during its operation are processed by the processor and then displayed on the screen.

All echo sounders for winter fishing work on the same principle, only there is a difference in the number of generated beams. The number of beams determines the level of sonar capture. At each model this angle is different, but on average it is from 20 to 24 degrees. The central beam is the most high-frequency, so it most clearly conveys the information received.

Dual-beam echo sounders for winter fishing have a capture angle of up to 60 degrees. The high-frequency beam is inside the low-frequency beam and allows a sharper image, while the low-frequency beam produces a blurry image, but covers a large area. The presence of the second ray makes it possible to obtain a three-dimensional image. The disadvantage is that it is projected onto a flat screen, and therefore inexperienced users may misunderstand the information provided. The greater the depth to be examined, the greater the difference between the information fed to the screen and the actual location of the fish in the pond. This is explained by the fact that the distances studied increase and the screen size remains constant.

Some echo sounders for winter fishing have such an option as determining the distance to the fish, but they are also imperfect as long as they determine the distance, they can not accurately indicate the direction in which the fish is located.

With the acquisition of experience, you can more accurately and correctly perceive the information displayed on the screen. If a fish symbol is displayed on the display, then it is harder to determine where it is located, and when the arc image function is turned on, this task is greatly facilitated.

The sounder needs to be set up correctly for operation. If you set a very high sensitivity of the device, it can show fish even where it does not exist, because it starts to perceive very small objects and even air bubbles or take turbid water at the bottom of the reservoir. The most correct is not to disrupt the exposed performance of the device. If you still decide to adjust it, then remember the factory settings, as, perhaps, you will have to return to them. All other echo sounder settings can be adjusted to your requirements.

An important characteristic is the number of pixels. The more of them, the clearer the image on the display. The presence of a color display practically does not affect the performance of the device. If you use a conventional screen, it is better to choose one that has more shades of gray. It is on the saturation of gray color that you can determine the density of the bottom, the more saturated it is, the harder the bottom.

If you plan to go for winter fishing on a large body of water, it is best to have an echo sounder with a built-in navigator. It will be safer with him.

The receipt of a picture is also affected by the way you position the sensor in water. The best sounder for winter fishing is one that has a special float, which allows it to be held at the right angle. Such devices are equipped with echo sounders Fisherman, Humminbird and many others.

Thus, for a good winter fishing, it is enough to purchase a high-quality echo sounder. And for greater comfort, you need an umbrella for winter fishing, and then without a catch you just will not stay.
