FISHFINDERS: What are they?


Fishfinders are echo-sounding systems, which are used to track down fishes in the oceans using active SONAR technology. These devices are basically used to locate the whereabouts of large groups of fishes as well as find out the floor of the ocean. It sends out SONAR rays into the water. As soon as the rays strike up a group of fish, they travel back to the fishfinder and images get displayed on the screen.

A modern fishfinder has a LCD or a CRT screen on which the images are displayed graphically. A fishfinder uses GPS technology, digital plotting of chart, electronic and compass displays, etc.

Fishfinders are portable devices, which makes it easy to operate by fishermen. These devices generally display an image of a fish on the screen to explain that it has detected the presence of fish. Many modern fishfinders are also capable of showing how many dead fish and how many live fish can be found in a particular area. The devices can be used to check the presence of rocks or seaweeds in the seabed. Using a special system of detection of finding the fingerprint using echo signals does this. This device is of great help to fishermen.
