How to use a fish finder for ice fishing?

Posted by Tutie on


Whether you are an avid fisherman or simply a hobby angler, fishing during the winter can be really tricky. With ice covering all over your favorite fishing spots, it becomes a real challenge to determine where to fish and where to not. Thanks to the science and technology that someone thought of inventing fish finders for helping us in such difficult situations. Fish finders are instruments that detect the location of fish and schools underwater, with the help of reflected pulses of sound energy, just like sonar (but they are not sonar) and help us perform easy ice fishing.

However, this machine is a bit fiddly to use in itself. It requires a sound knowledge and understanding of this instrument in order to use it rewardingly. Hence in this short article, I have laid out a few quick guidance tips to start with one such unit, for all you beginners. Read on.


The Arrangement

Setting up a fish finder for ice fishing is the first milestone after you have bought it and there are three steps in this –

  • Mounting the transducer: Mounting of the transducer depends on the type of the transducer you have. The most common one is Transom mount transducer. To mount a transom unit, you need to first find out the center of the boat where you want to affix the fish finder and then the transducer will go a little at the right.
  • Optimization: Set up the depth, range, and sensitivity of the instrument according to your location and requirements.
  • Additional settings: After optimization, modify the surface clarity, activate the noise canceling feature and adjust the color-line of the display according to your comfort and ease of monitoring.


After you have successfully installed your fish finder, you are ready to start reading it. Wait! Don’t you know how to read it? Chill, it’s easy; here is how to do it:

If your fish finder uses FishId, then you can simply identify a fish by looking at the icon that is set for a fish. This technique is useful for beginners and is easy but it is also a pretty less in accuracy because sometimes rocks and plants are also misinterpreted as fish.


If FishId is not available with your unit, then your fish finder will use arches to resemble fish. Each arch is one fish down there and the bigger the arch the bigger the fish.

So that’s it with fish finders. These tips are for beginning everything. You will learn more as you start using it.
