A fishfinder is a device used by boatmen to locate fish in the water. Fishfinders work on the technology of the SONAR (Sound Navigation and Ranging) system. A fishfinder is a very important device in today’s fishing process and also for those looking forward to fishing as a leisure activity.

A fishfinder displays the location of a fish in a digital screen that can be either of a LCD or a CRT type. The technology of the fishfinder was first used in the 90s and has been constantly up-graded since. In today’s times, the fishfinders’ technology is developed to include even systems like the GPS, electronic compasses and radar, making the device even more reliable than even before.
