How to Choose a Marine GPS and Chartplotter
A practical framework for choosing marine navigation displays that fit your helm and boating style.
Start With Helm Space
Measure width, depth, and viewing angle before comparing screen sizes. A great unit that does not fit well becomes hard to use underway.
Match Features to Water Type
Inshore anglers may prioritize sonar and quick route setup, while offshore boaters often need radar and AIS integration.
Plan Network Growth
Choose a platform that can expand into radar, autopilot, and engine data without replacing the core display.
Frequently Asked Questions
Is 9 inches enough for navigation?
Yes for many small to mid-size helms, but split-screen workflows usually benefit from 10-12 inch displays.
