Garmin GPSMAP 521 Chartplotter

Overview Garmin GPSMAP 521 Chartplotter

Garmin GPSMAP 521 Chartplotter is aimed at boaters who need a compact, dedicated navigation display with a simple operating layout. The 5-inch QVGA screen and improved high-speed digital design help keep chart viewing clear and responsive during normal route work.

The unit includes a satellite-enhanced worldwide basemap, a high-sensitivity internal GPS receiver and NMEA 2000 certification for broader system compatibility. It also supports optional GXM 51 services and BlueChart g2 Vision chart expansion for users who need more weather data or more detailed mapping.
