A Comprehensive Guide To Fish Finders

A Comprehensive Guide To Fish Finders

Most anglers have probably heard of fish finders by now, and there are typically two camps of fishers: those who use them and those who don’t. However, where do you stand if you don’t even know what a fish finder is? Don’t worry though, because we have you covered with our complete fish finder guide.

What Is A Fish Finder?

In the simplest terms, a fish finder is a device that is used to locate fish around you when you are fishing, and they work using sonar, much like submarines. Sonar is a form of echolocation, which is a type of navigation that consists of sending out a sound wave and detecting it when it bounces back.

Depending on the amount of time between the emission of the sound wave and the receipt of the echo, sonar can determine how far away a target is from you. Sonar can even tell you how large a target or object is, so you can imagine how useful it would be for fish finders, but there are many different types.

Types Of Fish Finders

You will find two primary fish finder varieties: the portable fish finder and the boat-mounted fish finder, so let’s take a look at the differences.

Mounted Fish Finder

A mounted model can range from a kayak fish finder all the way up to a transom-mounted model that is used on a full-sized fishing boat. Most of the time, these fish finders are much more powerful, being able to see to a greater depth, but they are also larger and more expensive.

Of course, this is not always the case, as fish finders can be mounted on very small boats and skiffs as well, so you may be able to find a mounted model that isn’t quite so pricey. In the end, however, these products tend to sacrifice a little bit of versatility in exchange for sheer power.

Portable Fish Finder

The portable variety is also referred to as a handheld fish finder, and it is exactly what it sounds like. These fish finders can be used in a wide range of different situations, making them the best choice for anglers that practice more than a single discipline.

While you can use a handheld fish finder on your boat, you will also be able to go ice fishing with one, as it is a crucial piece of equipment in that discipline. While these models tend to be a little more affordable, you will find some portable fish finders that are quite powerful and equally expensive.

Can It Be Harmful To Fish?

We've also been asked whether or not a GPS fish finder can be harmful to fish, and you won't have to worry about hurting the residents of the water. You would need a much more powerful sonar to have a chance of hurting fish with the power of the sound waves, so there isn't much of an issue.
