Trade Show Special Purchase!! On Sale through November 23rd!

The Garmin GPSMAP 421 is a compact chartplotter that features an ultra-bright 4” QVGA color display along with an improved high-speed digital design for increased map drawing and panning speeds. It’s ready to go with a built-in, satellite-enhanced worldwide basemap and an easy-to-use interface designed to help you navigate the open waters with ease. The GPSMAP 421 also accepts BlueChart g2 Vision cards for added features and functionality such as high-resolution satellite imagery, 3D views and Auto Guidance technology.

View Satellite-enhanced Worldwide Basemap

The Garmin GPSMAP 421 basemap contains worldwide satellite images in place of traditional maps. The GPSMAP 421 also comes standard with a high-sensitivity GPS receiver for superior satellite tracking and quicker acquisition times. In addition, the GPSMAP 421 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

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 GPSMAP 421s are also NMEA 2000-certified for easy connectivity with sensors, instruments and future marine offerings.
