The GPSMAP 420s is a sleek, space-saving chartplotter that features an ultra-bright 4" QVGA display, built-in satellite-enhanced worldwide basemap, and simplified user operation. The 420s also has an SD card slot so you can add additional features with the optional BlueChart g2 Vision card. The 420s's basemap contains worldwide satellite images in place of more traditional maps, and its SD card slot makes it easy to add additional maps without connecting to a computer. With fewer keys and a simple, intuitive interface, the 420s makes navigating your way through the water easy. The GPSMAP 420s comes with a powerful dual frequency transducer that clearly paints depth contours, fish targets and structure whether you're fishing in fresh water or off the coast. The 420s is also CANet compatible, so you can share sounder data with another chartplotter on your boat. « less
