Introduction to sounders

Echo sounder, also known as the sounder is an electronic device that detects the presence of fish and

These data are represented as an image on its screen.

Echo sounder is a useful accessory for fishing. It is now possible to find several models on the market.
obstacles and determines the depth of the water.



History and operation

Apparatus for the fisherman, the echo sounder was created by Carl Lowrance in the 50s. It is, however, that in the early 2000s it began to be used



This is a tool which is operable to provide a plurality of data to the fisherman as regards the survey area: it can be used for sensing the depth and nature of the water.

"It is therefore an effective tool because it can identify areas for fishing.

Sounder has a screen on which are displayed the necessary data. It propagates waves to detect objects and movements in the water and collect information.

In most cases, the issuance of these is at least 20 °. The tool also has a housing wherein are installed all electronic systems.

The four main types of existing sounders differ from each other by their display system. In France, only two of them can still be used: it is the LCD and video.

The different models are characterized by their coverage as well as the cone angle of their sensor. In most cases, those who are sold on the market have a 20 ° angle, but it is still possible to find more than 45 ° or more.

Models can also be differentiated by the options they offer as well as their design.



Why use it?

The echosounder is a useful tool for catching fish, and most importantly, have a good catch. Thanks to him, it is possible to identify and thus avoid obstacles in the survey area, as seagrass beds and slopes.

The sounder can give very precise. This device detects the presence of fish between waters, so it can better place the primers and the cane and take appropriate action.

"In short, it is used to improve fishing results.

Some models, sophisticated, provide very accurate and interesting. They detect the location of the lures and assembly within the water, in other words to allow fishing. They actually make the game more interesting fishing.

Pollsters upscale (such as Humminbird) provide interesting data that should however be able to use. It is especially necessary to understand the information that is to say, the images that appear on the screen.

Generally, a fish is symbolized by a rainbow, when the mode "Fish-Id" is not enabled. Fish size, moreover, is determined through the echoes they send.
