What is a Fish Finder?

A fish finder is a device used by anglers to locate either baitfish, sportfish, or structure in the water. This helps them increase their chances of landing a fish.

Fishfinders work by using SONAR. This relays a picture back up to a screen on the boat that the angler can use to determine if there are any fish or structure in the area that might attract fish.

Types of Fish Finders

There are several different types of fish finders. Many people have a preference for what they use in the boat. However, each has its own list of pros and cons.

Below, we’re going to go over the different types of fish finders. Look over the descriptions below and see which one is going to be the best for you and your fishing style.

Mountable

These are great if you want to put a fish finder on a boat. This could a drift boat, bass boat, pontoon, or even a kayak They will come with brackets that you can use to attach anywhere you wish.

These are great because they offer a secure way to keep watch of the fish finder. So, if you wind up hitting any chop or any bumps in the water you know that you’re fishfinder won’t go flying off the side of the boat.

Fixed

This is going to be similar to mountable. Or, it could even be the exact same thing. Often times mountable fish finders are considered fixed since they cannot be moved once you have installed them.

Again, these are great for when you want to have a spot on your boat that always gas a fish finder on it. Allowing you to easily glance over and see what may be beneath you.

Portable

A portable fish finder is ideal for someone who doesn’t have a boat. Instead, they have a small boat, kayak, or canoe. This allows you to easily grab and go.

Portable fish finders often have temporary brackets on them. This way you can mount them on your boat and then you can easily remove them when you are done for the day.

Handheld

These are typically used for ice fishing. Or it can be used went making out an inflatable raft or float tube. Something that does not have an area where you could mount a fish finder.

These are usually cheaper but can be a great asset for anglers who don’t have a boat with a mount but still want to be able to utilize a fish finder for their time out on the water.

Castable

These are relatively new in the fishing world. You can cast them out with a fly rod and reel and they work exactly like a fish fender would on a boat. Except you can pick exactly where you want to look.

These are great for shore anglers who want to know how deep an area is in front of them. Or for anglers who have kayaks and canoes who are floating a river. This allows them to see what is ahead of them before passing over.

When To Use a Fish Finder?

You can use a fish finder in just about any scenario you can think of. If fishing from the shore in a small bass pond then you can use the castable fish finder. This can only benefit you.

A fisherman fight against a pike. The man is sitting in the fishing inflatable boat. He also use a sonar fish finder to detect the fish underwater.

Ideally, the best time to use one is when you are fishing in deeper water where you cant see the bottom. This helps you find fish as well as structure. So deeper rivers, lakes, and saltwater are ideal for using a fish finder.

Do You Really Need a Fish Finder?

The short answer is no. You do not need a fish finder. That being said, it is only going t help you. There is a whole world beneath your boat and a fish finder will help you see it.

Whether it be baitfish, beds, structure, drop-offs, or a weed line. The fish finder will help you see all of these spots that the naked eye could miss but the fish are drawn to.

Features of the Best Fish Finders

Below, we’re going to cover some of the best features of each fish finder. Take a look and see which features are going to work best for you and how you prefer to fish.

GPS Integrated

This is great if you plan on fishing in a very large body of water. Whether it be a lake or the ocean, GPS integration is going to allow you to find spots that hold fish over and over again.

Fishing tackle set and fishfinder, echolot, sonar at the boat.

Also, the GPS will help when getting home too. This is ideal when fishing in a new body of water. Nothing worse than being tired at the end of the day and getting lost out on the water.

Cone Angle

Most people don’t know what a cone angle is on a fish finder. This is the area that the fish finder will cover on the bottom of the body of water. Usually, it’s measure by degrees, however, most people just refer to their cone angle as good, efficient, or effective.

What it looks like is an upside won ice cream cone of sound that gets shot out from the fish finder to the bottom of the water. Most are usually around 10-20 degrees.

Side Scan Vs. Down Scan

Down scan allows you to see what’s directly beneath the boat. This is ideal when fishing deep water so you can drop a lure off the side of the boat or guess what the depth of the water is in front of you.

Side-scan allows you to see an area that is off to the side of the boat. How far away from will depend on the maker of the fishfinder. Having both the side and down scan is ideal.

Mounting Type

There are a couple of different mount types for fish finders. There can be bracket mounts that will screw into the boat or onto a platform that will hold it in place. Making it a fixed mount.

Or there are types where a mount is screwed or drilled into the boat and then the fish finder is clicked into place. This is great for someone who wants to remove their finder when they the boat.

Vessel Specific Fish Finders

The removable fish finders are best used for drift boats, canoes, or kayaks. That way you can easily switch them out between different vessels and can take them out for safekeeping.

The fixed and mounted are best used on larger boats. Such as bass boats or pontoons, or any other type of boat that you plan on taking out to larger bodies of water.

Transducer

A transducer is going to send and receive signals for the fish finder. It is the heart of the echosounder system. Without it, the fish finder would not work and you’d be stuck with a blank screen.

Display

Displays will vary based on the size of the fish finder and the quality with which it is made. A well-made fish finder is going to have a much more clear display making it easier to see and read in low light or high light conditions.

A smaller screen or a cheaper fish finder will not be as clear. Leading to potential misreading or mistakes when reading the fish finder.

Frequency

The frequency on fish finders will usually range from 15hz to 200hz. However, you will find that the majority of the fish finders out there will either be using 50hz or 200hz.

There are some that even use 400hz. However, that is very rare. 15hz is best used to help locate large schools of fish or baitfish. The 200 Hz is used to find the exact location of the fish.
