Fishing might be considered by many to be an old people’s sport, but there is nothing quite like the thrill of the catch. If you are a fishing afficionado, chances are that an older family member introduced you to it when you were younger, or you’re just taking it up now by initiative of someone else who is probably your senior. Regardless of how you got into fishing, it is very likely that your first experiences have been more traditional in the sense of not using any new technology to help you catch fish. Well, we are here to argue that it is 2019 and there is no reason to keep yourself from using technology that will greatly help you have a better experience catching fish.
In this guide, we will focus on one particular piece of gear that some anglers are reluctant to use still: the fish finder. Also known as a sounder, it is called that way because they use sonar to ecolocate fish in the water where you are fishing. There are many different types of fish finders, and a lot of features to go over, so let’s take a look at some key qualities of these devices.
Fish finders: a general overview
Think of a fish finder as a GPS for water bodies. Instead of showing you the road, it shows you the water bed under you and instead of cars or directions, it shows you where fish are if they are captured by the signal. Finders use sonar to locate the fish, which means that fish will only appear in your finder if they swim within range when you are standing still. On the other hand, if you are on a boat and moving, the finder will show you the water beneath in real time and whether there are fish in it or not.
Fish finders manage to do this thanks to a set of transducers that can operate at different frequencies. Most finders nowadays work with either high or low frequencies, and the relationship between frequency and water depth is inversely proportional. The highest frequencies capture everything in more detail and, therefore, are best for shallower depths. Lower frequencies can reach deeper and are best for open water fishing, since anglers care not for detail but for detection and accuracy when trying to find fish.
You follow the fish tracking itself through a color display that clearly interprets the signal and maps out the area where the fish are or may appear. Besides that, you should also know that most of these finders require an external power source, which can be mounted in a waterproof casing on your boat when you install the transducers as well. The ins and outs of transducers will be something you learn over time, but for now what you must know are the basics of these devices so you can try them and make the most of your fishing experience.
