What Is A Fish Finder?

Best Fish Finders

Simply put, a fish finder is a device that is used to tell the water depth, temperature, and to also locate fish and their habitat. Different fish finders come with different features. Some have SONAR, while others have down scan and side scan imaging to help you find fish. All of this is in real-time as well.

The fish finder works by using a transducer. This helps show you exactly what is beneath you. You’ll find that some fish finders come with Bluetooth and wifi. A great freshwater fish finder will have an echomap, with high resolution. This helps you find the best fishing spots. 

Some fish finders are even castable now. They have clearvu, with chirp technology, with a cone angle. The depth finder works well and they have clear images. Compatibility is only with smartphones though. They can be used on the shore or a fishing boat, and surprisingly have great durability. 

The size of the fish finder will depend on what you prefer as well as the size of the boat you are on. Something that is small and lightweight will be ideal for something like a canoe or even a kayak.

Benefits Of Using A Fish Finder

Best Fish Finders

There are no downsides to using a fish finder. It will only help you when out on the water. Below, we’re going to go over a few reasons why it will help you. Check them out and see which ones you like the best!

Water Depth

Knowing the water depth is crucial in ice fishing and saltwater fishing. For ice fishing, you need a solid flasher. Anything with high quality and high frequency will work. Look for something in the 50-200 KHZ range. Fish like to hold at different water depths based on the temperature of the water. So knowing where you are can make a huge difference when you’re on the lookout for fish. 

Water Temperature

The water temperature is just as important as the water depth. The temperature of the water will determine exactly where the fish are and you can use this to target in on where they are going to be and how they are going to be reacting.


Having the ability to see structure underneath the water is going to put you further ahead than anglers who are just fishing using their yes. Yes, you can find laydowns and structure just by paddling around a lake. However, a whole new world opens up when you can actually see beneath the water.


It’s in the name after all. A fish finder is meant to locate fish and that’s what they all are going to do. Some may show different pictures on the screen of what may be fish but they all will guide you in the right direction. Also, if you’re in shallow water then a higher pixel count will help you see much more clearly. Sonar technology utilizing sound waves will also help.

Considerations Before Buying A Fish Finder

Below, we’re going to go over a few things you should think about before purchasing a fish finder. Think about what features you need exactly and then check out the list below. Find the one that is going to work the best for you!


Fish finders or fishing electronics can become expensive very quickly. So, think about what your budget may be, and then try and stick to it. Items can get into the thousands or tens of thousands very very quickly.


Just like prices, there are many different sizes for fish finders. The more expensive ones are going to be larger. However, that is not always true so don’t make that the rule when searching for fish finders.

Larger ones are ideal for larger boats because there is no weight limit in the same sense that a kayak has a weight limit. So, when you’re on a kayak using a fish finder you may need something very small and lightweight that has a four-inch display screen. Instead of a large 12-inch screen. Smaller fish finders are great portable fish finders as well. Some even have preloaded maps in them that allow for split-screen. 

Many of the fish finders with preloaded maps and Navionics allow for MicroSD cards. These hold extra maps. All you need to do is use the card slot. 


Fish Finder Imaging

There are a couple of different types of imaging out there for fish finders. Each has its own pros and cons so check them out below and see which one is going to work the best for you and your style of fishing.

Down Imaging

Downvision is going to give an image of what is directly beneath your boat. You’ll see the limbs hanging off of trees, or a fish sitting right on top of a stump waiting for suspecting prey. Or you could even see a bait ball hanging out beneath your boat. Down imaging is great for when you are in deep water and would like to jig.

Side Imaging

This is just like down imaging except it will show you what is on the sides of the boat. Making it perfect if you want a more stealthy approach to those spooky fish. The images appear exactly the same as down imaging. It will show you what is within a certain distance of where you are located.


This is the original imaging for fish finders. SONAR shows you blobs that are occurring beneath your boat. These Blobs could be structure, game fish, or sportfish. Luckily most of these products come with a guide so you can tell which is which. Also, after a little while of using these, you will be able to tell which is which without much effort.

Mount Type

You’ll also find that many different fish finders come with different mount types. Most are going to either be fixed or replaceable. The fixed mounts are great for use on larger boats, and the replaceable mounts are ideal for use on smaller boats such as jon boats, kayaks, or capes. This allows you to take it off and keep it locked up inside and safe.
