If your hobby is fishing, then you will be able to appreciate such a device as an echo sounder. Echo sounders are an indispensable tool for a fisherman. The sonar display shows the bottom map and the fish that are in the water column. Echo sounders can also "memorize" the most fishy places if the owner wishes.

Instructions
Step 1
The choice of an echo sounder is a responsible occupation. The future catch will depend on the qualities of the echo sounder. The first step in the selection is to determine the power of the device.
The higher the transmitter power, the better the signal will be transmitted even from great depths and in poor water conditions. True, the amount of power also affects the price of the echo sounder.
Step 2
Then you need to designate for yourself which converter the device will be with. The main characteristics of the transducer are the frequency at which it operates, the angle (cone) of radiation and the shape of the emitter.
The angle (cone) of radiation depends on the design of the emitter and can vary within a fairly wide range.
If air enters the echo signal field during operation of the echo sounder, this can significantly degrade the operation of the device. This is the case with echo sounders that have a flat emitting surface. But if the emitter has a well streamlined shape (for example, spherical), then the echo sounder will work stably even at high speeds.
Step 3
Now we are determined with the echo sounder receiver.
The receiver with high sensitivity allows receiving echoes from a wider cone than specified. But it should be borne in mind that the higher the sensitivity of the echo sounder, the more noise and interference on the screen. Therefore, it is best to choose a device with the ability to adjust the receiver sensitivity.
Step 4
The sounder screen size is easiest to determine if you know the intended fishing vessel. If fishing is planned from a small inflatable boat, then an echo sounder with a small screen will do. The large screen is convenient when on the boat and when navigating the boat. Also large screen echo sounders have more customizable features.
Step 5
The final step is either to choose a model on the Internet, order delivery and wait for the purchase, or go to a specialized store and buy a device directly from the echo sounder department.
