The new Garmin GPSMAP 740 & 740S GPS Touchscreen Chartplotters feature a brilliant 7" WVGA color display. Both the 740 & 740S come with a worldwide basemap as well as preloaded map data for all U.S. coastal areas, including Alaska and Hawaii, plus Explorer Charts for the Bahamas.

Both models feature an internal, high-sensitivity GPS receiver for superior satellite tracking and quicker acquisition times.
