View Satellite-enhanced Worldwide Basemap with the Garmin GPSMAP 421S

The Garmin GPSMAP 421S basemap contains worldwide satellite images in place of traditional maps. The Garmin GPSMAP 421S also comes standard with a high-sensitivity GPS receiver for superior satellite tracking and quicker acquisition times. In addition, the Garmin GPSMAP 421S can receive U.S. graphical weather data via optional GXM 51 satellite receiver/antenna. And with an SD card slot, it’s easy to add additional maps without connecting to a computer.

Add Sonar with the Garmin GPSMAP 421S

Where applicable, the sounder version, Garmin GPSMAP 421S, comes with a powerful dual-frequency transducer that clearly illustrates depth contours, fish targets and structures whether you’re fishing in freshwater or off the coast. The GPSMAP 421 and Garmin GPSMAP 421S are also NMEA 2000-certified for easy connectivity with sensors, instruments and future marine offerings.
