With so many electronics at hand specifically designed for fishing, it can be quite difficult to learn everything there is to know about how to use them. Let’s focus on fish finders for now, and on what the small dots appearing on your screen tell you.
In order to get better and more accurate information from your fish finder, pro anglers recommend shutting off the factory set filters, so that you limit the number of false positives that these can read within quite a short time. This means, of course, that you must know more what how to read your fish finder screen, but it is not as difficult as it may seem at first glance.
When you stumble upon of a school of fish, you will notice that they move in certain patterns. The dots on your screen can give you a lot of information on what kind of fish is out there, whether you can catch them or not, and other details. School formations are but a few, but they are a good source of info so you can learn right away whether you should pursue the fish or not.
There is a real treasure of information waiting for you on the screen of your fish finder. For instance, once you start detecting schools of fish, note down the depth at which they were found. This will give you a clear idea about the depth at which all the schools of fish will be in the area, so you will get more chances to hunt down the fish you want. This offers you the best opportunity to narrow down your search so you can really return home with some fish caught by you.
