Frequently Asked Questions

A GPS tells you where you are. A chartplotter displays that position on an electronic chart and adds navigation features like waypoints and routes. Most modern units combine both.

Radar is essential for offshore and night navigation. For small lake boats it's usually overkill. Your boating style determines whether it's worth the investment.

Installation difficulty varies. A handheld GPS is plug-and-play. A full chartplotter with transducer and radar requires proper wiring and mounting. We cover installation in our guides.
