    What is a fish Finder and how does it work

    A fish finder can be described as a tracking device used to locate fish in the water. Fish finders operate on the Sound Navigation and Ranging (SONAR) system. This system of operation is of significant importance in any activities related to fishing. Also referred to as sounders, the fish finder play a significant role in helping one to locate the right spot when fishing. The best fish finder should constitute two different parts that are the main unit and a transducer. The main unit has a display and is retained on the deck of the boat while the transducer is mounted on the hull. The display unit functions to identify the location of the fish using either an LCD or CRT screens. Other features constituting of a best fish finder include the GPS, radar, and electronic compasses.


    How a fish Finder works


    SONAR system


    According to ,The SONAR system functions to reflect back the signals send by the waves to the transmitter, which is then recorded and used to send a signal back to the screen. However, the difference of what kind of materials are signaled is determined by a different reflection of waves coming from fishes that does not much the waves triggered by the reflection of related objects like corals, and stones. These echoes differ in size and are subjected to form only when fishes are identified in the water, while different symbols forms indicate the presence of other materials. 


    Display Screen


    According to 11must, The display screen work to give a notification of the presence of fish in the water. Once a fish is detected, the screen displays a symbol that appears in the form of a fish. The display, however, changes with cruises experienced by the boat in places where the fish are identified. Such changes are witnessed by the fish symbol becoming arches on the screen. However, an angler can be used to identify the different objects in the water when the fish symbol feature is disabled.




    According to, The transducer functions to send out the sonar waves when the fishing device is turned on. These waves bump into materials present in the water and the nearby surroundings, then bounce back to the transducer that sends back the waves to the transmitter; a component in the main unit. The transmitter them measures the newly received sonar waves, and react by sending the measurements into the main unit through a single wire, which then displays the readings on the screen. The readings can either be displayed as spikes or fish icons on the screen. Spikes can only be witnessed when the screen shows flat areas and spikes (representing fish and other related objects) on the graph.


    Temperature sensitivity


    The sensitivity of the best fish finder; temperature and pressure sensitivity, play a significant role in locating the exact location of the fish. The device uses the temperature gauge to track the movements of a fish in order to switch possible locations in the course of fishing. As a result, it becomes possible to be alerted via the screen at times that the quantity of fishes is high. However, commercial fishermen prefer to use low-frequency, mostly between 50 to 200 kHz, while common people use a variety of frequencies to track the results.

    Wrapping it up, operating a fish finder is, however, not a walk in the park as it requires much attention than the common fishing devices. Using the best fish finder can, however, help you in choosing the most appropriate location to go fishing. Indeed, the using this kind of a fishing device can help you develop a liking for fishing, turning the activity into an amazing adventure.
