What is a Fish Finder?


Fish Finder is an instrument that lets you locate fish underwater with precision.


Fish finders work on the Sonar principle. In this technique, sound waves originating from beneath the surface of the water are detected and translated into location data. Fish finder utilize the active sonar principle. First, high-frequency sound waves are generated by the device which are fed into the waterbody. Then they hit fish and other things along the way and generate echo. This gets captured and recorded by the sonar units as fish location, density, and movement.


The data is then interpreted by a visualization device to display in the fish finder screen. As the fishes make their movement, the visualization scrolls across and create dynamic and ongoing 2D images of what’s underneath the surface.


The distance and location is calculated by measuring the time it takes by the sound wave to hit back the sonar detection device (also known as transducer) once it is emitted. Based on other factors like signal strength, the detector can determine other characteristics of the object, or fish in this case.


The other type of Sonar is passive sonar. In passive sonar principle, there’s no emission of sound waves and relies solely on listening to the sound waves generating underneath.

When Fish finders initially came to the market, their capabilities were very limited and could only perform a handful of operations like determining large-scale structure of the lake/pond, water depth, and sometimes inaccurate fish location.


Fast forward to 2019 and you will get supercharged fish finders with capabilities that provide a wealth of supplemental data to make your fishing activity a grand success. Among the many features, the GPS capability is a stand out feature for many fishing enthusiasts.


When you purchase a GPS-enabled fish finder, you locate not only the fish location, but also save the location for future fishing action. GPS stands for Global Positioning System. With the technology, you can pinpoint your own location accurately and navigate it whenever the need arises. This makes is easier for fishermen to track back to the location where they found success and angle at that location one more time. Thus it saves both time and effort.

Sonar Power and Frequency


The more powerful the fish finder, the clearer and accurate readings you will get. Power output is measured in watts and is symbolized by “W”. When more power is delivered, signals are send to far out enough and deeper into the water. The waves will have more energy when they hit the fish and reflect back, resulting in a clearer image.


Also check for frequency in which the device operates. The device sends out sound waves of a certain frequency. Lower frequency is better when you’re dealing with great depth, while higher frequency is considered better for shallow water. The best Fish finder GPS combos are able to send out multiple frequencies, and hence are for multi-purpose.




A good display will do justification to high power and multiple frequency. The screen should have high resolution and large enough to be handled easily at an arm’s distance. The more advanced fish finder units have split-screen mode which enables you to visualize two different data (like fish data and GPS information) simultaneously. Furthermore, you have the option of choosing between a touchscreen display and normal TFT/LED display.

But the best fish finder GPS combos have packed lots of capabilities packed into relative smaller size. So it might make sense to purchase premium ones for better portability experience.




Lastly, don’t forget the budget range in which you are looking for a Fish finder. They can range from $100 to $500 and upwards depending upon brand and features. However, you shouldn’t go for the cheapest option available. If you regularly go to fishing and want to make a long term investment, then it is better to purchase fish finder GPS combos that are in the upper-middle range.
