Tips for Choosing the Best Fish Finder for Trolling Motor

best fish finder

A fish finder is a useful device that allows you to see fish underwater and surrounding structures and objects.

After detection, all of these are displayed on the fish finder’s screen. While buying a fish finder, you must consider some important factors. Our buyers’ guide mentions some of those factors that will help you make a decision:

Transducer Mount

The transducer is the main component of a fish finder. It is responsible for converting energy signals from one form to another.

This case converts electrical signals and sends out sound waves, which come back as echoes and convert back. These waves carry information about the depth, location, fish, objects, contours, etc.

The transducer mount attaches it to the trolling motor. Some require additional parts for attachment, while some fish finders already include a transducer mount.

It is best to go for the latter type of fish finder if you wish to avoid unnecessary hassle and save time.

Battery

When a fish finder is low on power, it can give inaccurate readings, and you will end up not catching any fish at all. Make sure to go through the battery requirements of the fish finder.

Some do not need an external power source and run on batteries, while some require external power. In this case, try to keep the power source of your fish finder separate from the source for your trolling motor.

Waterproof Feature

When you go fishing, water splashes will inevitably come into the boat, the trolling motor, and the fish finder.

A good fish finder is waterproof. If it is not, then it will not run properly the instant it makes contact with water. Hence, it would help if you had a fish finder resistant to water and can function even after getting wet.

Screen Display

While the above features are important, the display screen of the fish finder is equally crucial. The screen size should be appropriate, but the display quality is even more important than the size.

It should show clear, crisp, bright, and vibrant images. The screen should be visible even under bright sunlight; otherwise, you will not be able to go fishing during the daytime.

A colored screen is preferable since it will have more pixel colors that will contribute to a clear picture that displays what the sonar detects.

Navigational Capabilities

Low-budget fish finders usually do not include navigational features. Although you do not need a high-functioning GPS to catch a fish, it certainly helps you keep track of your previously visited locations.

Thus, you can completely enjoy the trip without worrying about where you came from or where the previous fishing location was.

Best Fish Finder for Trolling Motor FAQs

Let’s address some frequently asked questions that you may have in your mind as well:

✅ Should I buy a fish finder with a colored screen or with a black-and-white screen?

Color screens are more preferable since it is easier to make out the details when you have different colors on the screen. The information relayed by your transducer will be easy to understand and read. Colored screens are also easier to read in sunlight.

✅ How do fish finders work?

Fish finders make use of sonar technology. Sonar works by emitting high-frequency sound waves into the water. When these waves come across any object, they bounce off and return. These waves are then processed by converting them into electrical signals. The data is visually displayed on the fish finder’s screen, and you can see everything on the screen. As you move across the water, the environment also changes, and you keep getting new visuals based on the information received by the sonar.

✅ Do I need the GPS feature in my fish finder?

No, it is not a necessary feature. However, it is useful as it helps keep track of coordinates while fishing, so you do not have to worry about doing that yourself.

Conclusion

Whether you are a novice or a professional fisher, it is easy to get confused by the plethora of fish finders available. Each model has its own unique features, price range, and capabilities. Therefore, you should choose the one that suits your needs the best.

The Garmin Striker 4 is our top pick. It is available at a reasonable price and with good features. It uses CHIRP sonar technology and has built-in mapping features.
