What is a Fishfinder & How does it work?


In the deep ocean, there are few specific spots where a school of fishes crowds together because it’s the most nutrient-rich point in the ocean. These are called the Hotspots, where different species of fishes can be found converging in this spot.


A fish finder basically works on the principle of Ultrasonic reflection and SONAR (Sound Navigation and Ranging) system.


An Ultrasonic or sonar wave is transmitted into the sea, and a part of the signal is echoed back or reflected back to the device. So when a part of the signal gets reflected back, the device can give the exact location of the seabed, obstacles, water depth, distribution of fish school, and any underwater information can be obtained with the help of a fish finder.


This device is helpful in not only finding the hotspot locations of marine life and gives information about any obstacles like huge rock or underwater debris. The device can also calculate the density of the obstacle.

Display, working, and installation of a Fishfinder device


A fish finder has a display screen that displays the density of the fish school or coral reefs present underwater. If the density is high, then it displays a reddish color with a fish symbol on top, so you don’t get confused with what object it is; if the density is low, then you get a blue color on the screen with the exact location of fish school underwater.


Over decades, the Fishfinder has gone through constant upgrades that now even come with GPS, radar, and navigation systems.

Typically, the device consists of two parts.


  • Display screen An LCD screen that should be placed in the wheelhouse for easy access.


  • A transducer This device is mounted on the boat’s bottom to transmit and receive the signal.


            The installation of a transducer is a bit tacky because you either have to do it in the hull or through the hull. The positioning of this transducer plays a vital role in determining the location of any objects or fish. Since the entire performance of a fish finder relies on the transducer, it’s advised to call up a technical dealer who could help you with the transducer installation. Once it’s done, then you can get all the signals on your little LCD screen.
