  • Company Profile


The GPSMAP 421s 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 421s also accepts BlueChart g2 Vision cards for added features and functionality such as high-resolution satellite imagery, 3D views and Auto Guidance technology and a powerful dual-frequency fish finder that clearly illustrates depth contours, fish targets and structures whether you?re fishing in freshwater or off the coast.

View Satellite-enhanced Worldwide Basemap

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