An echo sounder is a highly strategic piece of equipment for an angler. This accessory gives him access to information that a few years ago was unthinkable. For this device to perform its function, you must choose it with great care.
The principle of an echo sounder
The term echo sounder is used to refer to a device whose purpose is to make a small map of a given underwater environment. In the context of fishing, it is mainly a question of sounding the bottom of the water, in order to have a more or less precise image of the area. The main interest lies in the ability to visualise the fish present in the water.
It can also be used to avoid running directly into obstacles when in a boat. Sometimes the seabed has elements such as rocks that can cut into and damage the boat. It is therefore up to you to make the best decision for this.
Technical details of an echo sounder
To use a fishfinder echo sounder, you will have to immerse the probe in the water. This is connected to a box that receives and processes the transmitted and received waves. The sounder can be wired to the box, or it can be connected to a wireless network.
Depending on the type of monitor you decide to use, you will get a 2D, 3D lateral or 3D vertical image. The range of the waves will depend on the power of your device. Other details that will affect the comfort of use, such as the overall autonomy.
Choose according to the type of environment
A fishfinder echo s ounder should be chosen according to whether you plan to go fishing in the sea or in fresh water. This changes a few details, including the general performance requirements. As the sea is a vast environment, it is essential to have waves that can go far.
Secondly, there are also details such as frequency that need to be addressed. This is very important, and the frequency range must match the environment. An echo sounder for sea fishing should be able to transmit 50kHz waves. For freshwater fishing, the range is from 83 kHz to 200 kHz.
Choosing according to your budget
This is an important detail, and depending on how much you can afford, it may be better to choose one echo sounder over another. Models such as the Lowrance Hook2 GPS fishfinder are one of the best value for money.
It will allow you to get the minimum acceptable performance without spending too much. Secondly, for sea fishing, it’s really best to go for models that are powerful enough. This may therefore require a small investment on your part. The use of these accessories in fresh water is less demanding.
