The GPSMAP 431s 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 basemap preloaded with U.S. Garmin Lakes and an easy-to-use interface designed to help you navigate the open waters with ease.

And with an SD card slot, it’s easy to add additional maps without connecting to a computer.
