7 Inch vs 9 Inch Fish Finder Specs
Display Size
The Garmin Striker Vivid 7sv features a 7-inch display, offering a compact footprint for smaller boats or tight console spaces. The Lowrance Eagle 9 TripleShot HD provides a larger 9-inch IPS screen.

The 7-inch model remains sufficient for basic sonar and GPS needs without taking up much dash space.
Sonar Technology
