How to Choose the Best Fish Finder: The Ultimate Buying Guide

Patience is a virtue that every angler needs to catch fish successfully. You need to cast and wait. At times your patience may be tested as you sit for hours wondering where all the fish is or what’s happening beneath your boat. But this doesn’t have to be the case when you bring a fish finder along. Just like the name, this is a device that scans the area around you and lets you find the fish. More to that, it can also help you know the depth of the water and if there are any obstructions such as rocks beneath you.

Fish Finder Terminology

There are two common words that you will come across when looking for an ideal fish finder for your fishing excursions. They are;

SONAR – This is an acronym for Sound Navigation and Ranging, which is a technology that scans the water and picks up a sound echo which is then transmitted to the device. The technology is so effective that deep sea fishing fully relies on SONAR to find schools of fish.

CHIRP – This stands for Compressed High-Intensity Radiated Pulse which sends high pulse energy into the water column and uses frequencies to track the bottom of the water with better accuracy and at a faster speed.

Basic Parts of a Fish Finder

A fish finder is made up of two basic parts;

Transducer – This is considered the heart of a fish finder since it’s the one that sends out sound energy and receives the echoes which then interprets what’s happening in the water. Transducers come in different mounting styles where you can get the thru-hull which goes through a hole in the hull or the transom mount that goes at the back of the hull.

Display – Once the signal has been interpreted; it shows on the fish finder’s display. Fish finders have different display features depending on the manufacturer. The display can be colored or black and white, touch or use of buttons, have a backlight for night visibility and many more features.

Factors to Consider When Buying a Fish Finder

The following features are important considerations when shopping for a fish finder;

  • Cone and beam angles – The size of the cone formed by a transducer is important in the performance of a fish finder. The wider the cone beam, the larger the area covered by the device. However, as the beam gets wider, the sensitivity to the depth of water reduces. The degree of the cone angle may range between 9 to 90 degrees. For advanced angling, a device with a dual or triple beam is better for more details.
  • Display – You will come across a colored or black and white display. It’ important to ensure that the graphics on display are easy to read and interpret. Some of the devices have complicated set up software, which some find a headache to use. If you are into night fishing, ensure that your fish finder has a backlight for better visibility.
  • Frequencies – You will find that most transducers work with different frequencies, which greatly influences the cone angle. When fishing in shallow water, higher frequencies ranging between 192 and 200 KHz are preferred while 50KHz will be fine for deep water fishing.
  • Charging – Most of the fish finders are either battery powered or charged using USB. You have to ensure that the device will provide you with adequate power to take you for an extended period when out fishing.
  • Other features – Other important considerations are the ease of mounting or using the device. Some operated best when handheld while others need to mounted. There are those that come with WIFI connectivity for easy recording and pairing with other devices.


A fish finder is the ideal companion when out in the water and will help you relax and enjoy the experience rather than spend hours guessing where the to find the fish. We hope that this review has provided valuable information on the best fish finders available in the market that will turn you into a celebrated angler in your home.
