What Is a Fish Finder?

A fish finder is a device that will allow you to see the bottom or the sides of the body of water you’re in. It’ll also allow you to see what is in the middle of the water column.

This will help you detect game fish, bait fish, drops offs, humps, ledges, brush, and lay downs. Any area where a fish might be sitting and waiting you’ll be able to see as well.

Types of Fish Finders for Under $500

There are several different types of fish finders for under $500. However, it can be daunting when you’re looking at the list, especially if you’re not familiar with the vocabulary.

So, below I’ll go over the different types in detail. This way you can have a better understanding of what you need for fishing and what you should be looking for.


Mountable fish finders are great if you want something stable, but you also want to remove it after a day of fishing. Mountable fish finders can be used on many different types of vessels.

These come with brackets that you can mount anywhere on your boat. The bracket will keep it stable during your day out, and then you can remove it and keep it inside your home or in your truck where it’s safe.


A fixed fish finder is similar to a mountable fish finder. They both come with brackets that will keep your fish finder stable in rough conditions.

However, you’ll find that you won’t be able to remove it once you’ve attached it to your boat. These are great for larger boats that are kept secure.


Portable fish finders are ideal for anglers who are shore fishing or want to use them in kayaks, canoes, or other small vessels. This is because they’re usually smaller and easier to move around, making these the best kayak fish finders.

These are also great for ice fishing. Typically they don’t come with all of the bells and whistles that some of the fixed and mountable products do. They still work very well and will help you catch more fish.


Handhelds are great for shore fishing and other smaller vessels. These can easily fit into either your pocket or inside of a tackle box. They’re perfect for someone who wants to lighten their load.

These can be used for larger boats, although this doesn’t make too much sense. If you have a larger boat and you’re fishing in big water, then a larger fixed fish finder will serve you better.


These are the new guys on the fish finder scene. Everyone having a smartphone in their pocket has given rise to the castable fish finder. They could also be the best fish finders for a kayak.

Many of these are a bobber that you cast out and work similarly to the one in your boat, except the screen is accessed through an app on your phone.

When to Use a Fish Finder

Anytime you find yourself out on the water, you can use a fish finder. It doesn’t matter if you plan on fishing from a skiff, a jon boat, the shore, or an inner tube. There’s a fish finder for you.

No longer do you have to purchase a bass boat in order to utilize a fish finder. Anyone can use one these days, and this will lead to more success on the water.

Do You Really Need a Fish Finder?

You don’t need a fish finder in order to go out and have success. You can use your eyes to locate lay downs or any other structure you can notice from the shore or a boat.

That being said, using a fish finder will significantly improve the amount of fish you catch. It will open up whole new spots of the water that you didn’t even know were there.

Features of the Best Fish Finders for Under $500

Below, I’ll go over some of the best features of a $500 fish finder. Check them out and see which one will be the best for you and your style of fishing.

A Diagram Showing Important Features To Look For In Fish Finders

GPS Integrated

GPS integration is a great feature to have in a fish finder. This usually means that the device is equipped with a waypoint marking feature, which makes it easier to find your previously successful spots.

Also, having GPS means that you can navigate waterways more efficiently. This is ideal if you’re fishing on a new body of water for the first time.

Side Scan vs Down Scan

Side scan will give you an image of what’s located on the side of your boat. This is ideal for narrow waterways that may have a lot of structure on the sides.

Down scan gives you an image of what’s beneath your boat. This is great for fishing in deeper water, such as lakes or the ocean. Down scan is great for jigging beneath your boat.

Mounting Type

The mount type all depends on what’s either best for you or for the boat that you have. A fixed mount is ideal for larger vessels that may be in some chop. Fixed is sturdier and usually has a larger screen.

Mountable and removable is great for smaller boats. This way you can take off the fish finder at the end of the day and either bring it inside or lock it up in your car where it’s safe.

Cone Angle

The degree of the cone angle will tell you exactly how much of the bottom of the water column the device will show you on the screen.

It looks like an upside-down ice cream cone and sends down a signal to the bottom of the river or lake. The signal it receives back shows you what’s on the bottom as well as the water column.

Vessel Specific Fish Finders for Under $500

Most fish finders under $500 are on the smaller side, making them great for smaller boats, such as jon boats, kayaks, or canoes.

Since the screens are smaller, you won’t be able to see them as well as on larger boats. So, you could mount it on a big bass boat, but you’d need to be close up to see what’s on the screen.


This is the heart of your fish finder. It’s what sends and receives the signals that it then puts on the screen. A good transducer will make all of the difference in your fish finder.

These can sometimes be tricky to mount onto your boat. This is true if you have something smaller, such as a kayak or a canoe, where it can be difficult to find spots to mount it.


The display is very important. It needs to have just the correct amount of brightness so that the sun doesn’t overpower the screen on a really sunny day.

Also, it needs to be large enough that you can see it without having the squint or move too close. Ideally, a larger screen is great for larger boats, and smaller screens are best for small boats.


Most frequencies are between 50 kHz and 200 kHz. However, you will find that most of the frequencies out there are set to 50 kHz.

You can find some that are larger than 200 kHz. However, those are typically reserved for commercial fishermen in deep water.
