So far the angler will think of everything in his passion to be more successful than the rival: all kinds of bait and bait, super-catching tackle, and now also an echo sounder. Fortunately, this device does not harm the fish.
What is an echo sounder
An echo sounder is a device that scans the water column using echolocation. The main task of the device was initially to determine the depth. A primitive lot is a weight on a long cord, on which knots are tied at certain distances. The beginning of the use of echolocation for this purpose showed that some of the emitted signals directed to the bottom are reflected from fish schools, as from any object in their path. This was immediately adopted by the fishing vessels. From the picture obtained on the display, you can estimate the size of the fish school and set the depth of its location. Today, not a single fishing vessel can do without an echo sounder, or sonar.
Angler's Portable Sonar
Soon, at first, of course, abroad, fishermen began to use echolocation for catching various fish, including in inland waters. At the moment, popular models with a 4-inch black-and-white screen can be purchased at a price of 5,500 rubles. The cone angle of the emitted beam of up to 60 degrees allows you to inspect the larger the bottom area, the deeper you are. And the available depths for echolocation are from 1 to 182 m without loss of image clarity on the display. The clarity of the picture is provided by a good frequency of 220 kHz, displaying the smallest details. At dusk and when fishing at night, you can turn on the screen backlight for a long time without damaging the battery. The echo sounder is powered by a 12-volt rechargeable battery.
Fishfinder fishing
Due to the fact that the sent locating signal is directed vertically downward, it is possible to fish with it in the warm season from a boat or footbridges protruding far into the water. In winter, the echo sounder is a great helper in ice fishing. It must be remembered that the echo sounder is not looking for fish. He can show its presence at a certain depth at a certain brief moment in time. But the main purpose of the device is still to determine the depth and study the bottom: relief, density of the bottom soil, the presence or absence of vegetation, foreign objects. Based on the picture on the display of the device, you choose a place for fishing. As an additional function, the echo sounder will give you the water temperature, which is essential for the potential biting intensity. When trolling from a boat, it will determine your movement speed.
