Fish Finders Buyer’s Guide

There’s a lot of technical terms being thrown around in these reviews, so it may benefit you to brush up on some of the features to look for when purchasing the best fish finder for your needs. Here’s a quick breakdown of some terms you’ll often see and how they relate to your fish finder experience.

Transducers And Sonar Frequency: There are several types of transducers used within fish finders, but all of them operate under the same principles. Higher frequency sonar signals eliminate more interference from the screen and produce clearer images, while lower frequency signals penetrate deep water more effectively. Most experts recommend using at least a 200kHz signal for waters up to 200 feet deep, and a 50 to 80 kHz signal for waters deeper than 200 feet.

Power: Power, which is measured in watts, is a big factor to consider with fish finders. Because fish finders decipher sonar signals they receive from the transducer, models with more power display readings faster and penetrate deeper water. Models with lower power are better suited for shallow water.

Screen Resolution: The images on your fish finder’s LCD screen get sharper or wider based on how many pixels it has. More vertical pixels improve the resolution at lower depths, while the amount of horizontal pixels determines how long a fish stays onscreen before swimming out of view. The amount of pixels per square inch on your display also improves an image’s overall detail and gives you a better look at what’s below you.

Keep these terms in mind when comparing prices and features to find the Best Fish Finder!
