Fish finders vary from model to model. Some have basic features and others have many advanced ones. Many fish finders are for professional use and others are entry-level devices aimed at people who want to try the technology out.

The prices can vary to a great extent from device to device, and you should be well informed for spending on any of them.  We have done our research and outlined the best fish finder models with a range of features and prices.

Fish Finder Technology

You will need to spend some time if you want to learn how to use them in right way. To easily understand how a fish finder functions and you can know more about fish finder features, we have compiled this buying guide. With the information gathered, you will get to make the best choice.


The transducer is the main part of the fish locator. It transmits the sound waves and shows what is below the surface of the water. The sonar signal -the transducer sends into the water bounces off of the objects below the water surface and gets picked up by the transducer. The signal is translated in a picture.

Display (Size, Resolution, Color/Mono)

The display is all about pixels. The more pixels the device has, the better the resolution. It’s an important factor to consider. More pixels mean a higher price of the fish finder.

We suggest you to go for a minimum of 240(v) x 160(h) pixels of the screen. This screen will give a pretty blocky image. The models’ displays are available in various sizes. A larger screen will give you a clearer picture and better quality.


The fish finder’s power is an essential feature to consider to choose your preference. A fish finder with a higher wattage is more effective, it can display readings and more usable depth with better speed. For low depth water, you can use a unit with lesser wattage.

If you are planning to fish in deep waters, look for more powerful units.


Every fish finder has a different frequency, a major aspect of the transducer. The frequency has a direct relation to the angle of the cone. The transducers have frequencies of 50, 83, 192 or 200 kHz. Transducers with higher frequency will display more detail on the screen.

You can find models that offer dual, single and multiple frequencies.

Portable or Fixed

Fish finders come in different forms. We have a portable fish finder and self-sufficient or a fixed unit whereby you will need to mount onto your boat or canoe. Portable fish finders are more suitable for those who lease their boat or if you ice fish.

They usually come with a battery power supply and a carrying case. Most of the fish locators come with the transom mount for installation, the portable units come with the transducer already attached to the transom with the use of a suction cup.

A fixed unit is more suitable for more settled fishers and watercraft owners. They will be able to mount in any precise location on their boat. Based on your preference or needs, you can mount the transducer on the stern, hull and trolling engine.
