The 440s has preloaded detailed maps that cover all U.S. coastal areas, including Alaska and Hawaii. For areas outside the U.S., the 440s has a worldwide basemap with 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 440s makes navigating your way through the water easy.
The GPSMAP 440s comes with a powerful dual frequency transducer that clearly paints depth contours, fish targets and structure. It's also CANet compatible, so you can share sounder data with another chartplotter on your boat.
