Buying Guide: How to Choose Fish Finders

How to Choose a Fish Finder

Not Just for Pros
Modern fish finders are accessible, affordable, and genuinely useful. You don't need to read sonar like a Navy submarine operator.

### Key Technologies
CHIRP sonar: Sends multiple frequencies for clearer images. Worth the upgrade over traditional sonar.

Down Imaging/DownScan: Photo-like images of what's beneath you. Shows structure detail.

Side Imaging/SideScan: See structure and fish off to the sides of your boat.

### Screen Size Matters
3-4": Kayak and small boat basics
- 5-7": Sweet spot for most anglers
- 9"+: Tournament and serious use

### GPS: More Valuable Than You Think
Mark productive spots, navigate safely, track your path. Built-in GPS is worth the small premium.

Frequently Asked Questions About Fish Finders

Will a fish finder guarantee I catch more fish?

It guarantees you'll spend less time fishing dead water. Finding structure and baitfish puts you in the right place. You still need to present correctly.

Can I use a fish finder from shore?

Castable fish finders like Deeper work from shore. Traditional units need boat mounting. Some kayak anglers mount units on float tubes.

What's the difference between CHIRP and regular sonar?

CHIRP sends multiple frequencies simultaneously instead of one. Result: better target separation, clearer images, less noise. Worth the upgrade.
