Buying Guide: Consideration Before Purchasing a Fish Finder

A fish finder is a Bluetooth, wireless, or GPS device that is used to find fish underwater.

Not only can it tell you the depth and water temperature, but it also has a sonar system that emits an electromagnetic signal to search for fish below.

You can find one of these fish finders in any price range from under $100 to several thousand dollars.

We’ve created a list of important factors to consider when purchasing a fish finder under $100. Here, are some things you should know before buying a fish finder.


Depending on what model you buy, the price will range from under $100 to higher. So you must know what you are getting into.

Generally, you should expect to pay a few hundred dollars for the device and one or two transducers, depending on the model.


Fishfinders are typically designed to be worn on a harness or around the neck. Generally, there are three different sizes of transducers: small, medium, and large.

Small transducers are just under 3.5 inches in length, medium transducers range from 4.5 to 8 inches and large ones measure 8 to 13 inches.

With all of the features that these transducers offer, it is important to make sure that you get the right size for your needs.

Battery Life:

Buying a fish finder with long battery life is preferable. A long-lasting battery is important so that you don’t have to change batteries every couple of days.

This will also prevent you from having to come back to the fish tank when your battery has run out.


A good fish finder will have a lot of features. These features include; live video, sonar detection, depth finder, target imaging, and more.

You can also browse various online fish finder reviews to make your buying decision easier.


Most fish finders have a warranty. Some might have a year warranty and others have a 2-5 year warranty. Make sure you research this policy thoroughly.

Typically, a warranty is a great option for your next fish finder purchase, as it gives you peace of mind when it comes to purchasing.

In case something should go wrong with the fish finder, it has a warranty to support you.

Auto Setting:

If you don’t know how to set a fish finder, you’ll be hard-pressed to fish with this device.

Having a large database to choose from can help you when selecting the settings that are best for you.

For example, you could choose the auto setting that allows you to start fishing by just pointing the device toward the current’s depth.

You may want to adjust this according to the fish you are targeting.

Which is better: handheld or waterproof fish finders?

A handheld fish finder is easy to use and less expensive to purchase, but they are generally not waterproof.

A waterproof fish finder is more difficult to use because it has to be connected to a long power cord, or batteries that need replacement often.

They are also more expensive since they have the battery case built-in and have a complete line of fish finders, including Depth Finders, Sonar Fishfinders, and Vibrating Seat Depth Finders.

Just like with many other products today, handheld and waterproof fish finders both have their advantages and disadvantages.

The main difference between the two is that a waterproof fish finder will have a display screen that can be easily removed from its housing for underwater viewing whereas a handheld unit will usually just be a conventional fish finder.

This can be good for durability, but it also makes the device heavier and less durable than waterproof models.

What Features Do You Want To A Fish Finder?

First, think about what features are important to you. For example, if you are a novice angler, you probably want to start with a device that only has an on/off switch for underwater functioning.

With most devices, a button on the side of the unit can be used to toggle between day and night mode.

Or, if you are an experienced angler, you can use the keyhole touch panel to control the functions.

There are several types of fish finders available. These include depth finders, sonar units, and vibrating seat depth finders.

To summarise, you should choose a good fish finder that fulfills your needs on your budget. It should be durable and reliable to last for years.

Do fish finders on kayaks work?

Yes, they work! Fish finders use sonar to send out a sound pulse and then track the return signal to identify objects under the water. They come in both portable and mounted versions and can be helpful in finding fish, mapping the bottom of a lake or river, and locating obstacles underwater.


Buying the best fish finder on a budget is a great way to get some fresh, local seafood, especially if you are an avid outdoorsman.

No matter the price, every fish finder can be beneficial. It’s important to do some research and shop around to find the best fish finder.
