The Buying Guide - How To Buy A Fish Finder Under 400

In a market full of options, you're better off applying the latest buying tips to make a sound decision. Some of the extremely important factors to consider include:

Quality of the Display Screen

The kind of display screen you settle for can significantly affect your user experience. For that reason, you'd better off settling for a fish finder with a significantly big display screen. It should also be backlit for an easy time viewing it under the glare of the sunlight.

The Kind of Transducer Used

The transducer is the main device that a finder uses to capture Sonar wave signals. In other words, if you get one that's of high-quality, you'd be best placed to make a catch. Basically, the signal generated by the transducer is what is then converted into an image.

So, don't cut corners. We'd recommend going for a high-quality transducer which can help you make some highly-informed decisions.

What's The Frequency?

Normally, if the frequency is high, you get better chances of capturing more detailed shots. Ultimately, the kind of frequency you settle for should be determined by the depth of the water you're fishing.

If venturing into the deep waters, we'd recommend going for a 50 KHz frequency level. As for shallow water surfaces, a 200 KHz would suffice.

Which One Is The Best?

In our opinion, the best under 400 fish finder is the Humminbird Helix 5 GPS 410210-1Chirp G2 Fish Finder. It has a pretty well-made transducer, a high-level of frequency and a backlit screen. We generally, feel that it offers a better deal than everyone else that is.

Final Thoughts

It's high time you start approaching the deep waters with confidence. And as it turns out, it takes more than just the usual fishing gear to get things done. That's why you need to find the best fish finder for the money.
