Buyer’s Guide — How to Choose a Marine Chartplotter

The biggest decision is screen size vs helm space. A 7‑inch unit is perfect for most cockpits, while 9–12 inch displays are ideal for offshore passagemaking.

Networking is essential — choose a chartplotter that integrates cleanly with your AIS, radar, autopilot, and depth instruments. Garmin works best with Garmin; Raymarine with Raymarine.

Finally, choose the chart type that suits your cruising grounds. BlueChart g3, Navionics, and C‑Map all have strengths depending on where you sail.

Which Chartplotter Should You Choose?

Choose GPSMAP 7x3 for most cruising boats.

Choose GPSMAP 9x3 for offshore sailing and larger helms.

Choose Axiom 9 if you use Raymarine.
