BUYING GUIDE
Down Imaging vs Side Imaging
Down imaging shows what's directly below your boat — great for depth and fish detection. Side imaging scans left and right, revealing structure, cover, and fish over a much wider area. Side imaging costs more but is transformative for finding new spots.

Garmin STRIKER Vivid 7cv
A great example of this in practice — check current price on Amazon.
Screen Size for Fish Finders
A 7-inch screen is the sweet spot for most boats. Larger screens (9-12 inches) help with split-view sonar but take up more console space. Kayak anglers may prefer 5-inch or castable units.
