4” Color Chartplotter with Pre-Loaded Inland Lake Charts!.
The Garmin GPSMAP 431 makes navigating inland lakes a cinch by incorporating a 4" color display with pre-loaded inland lakes and high speed processors for fast map redraws. The Garmin GPSMAP 431 packs detail of over 14,000 lakes into this compact unit. Pre-loaded to every Garmin 431 is detail of inland lakes showing depth contours, boat ramps, mile markers, hazards and marinas. The GPSMAP 431’s 4” QVGA display is crisp and clear, and viewable in any lighting situation. The Garmin 431s’ built in high-sensitivity antenna is perfect for almost any boat and eliminates the need for the optional GA-29 Remote Antenna in most applications. The GPSMAP 431 is great on a small boat with limited space.
The Garmin GPSMAP 431 is also compatible with the G2 Vision data cards. The BlueChart G2 data features detailed coastlines, navaids, port plans, depth contours, wrecks, and restricted areas, as well as tide and current data. This data can be further enhanced in the GPSMAP 431 with the addition of a BlueChart G2 vision chart. The G2 vision charts will add high-resolution photomapping detail, real picture aerial images of ports, harbors, marinas, waterways, points of interest and other navigation landmarks.
The GPSMAP 431 also features audible alarms for anchor drag, arrival to a waypoint or destination, 10 proximity waypoints, off-course, and clock as well as low battery voltage. The Garmin 431 also has loads of memory for waypoints and tracks; storing up to 3,000 waypoints with name and graphical symbol and 10,000 track log points with room to save 15 tracks with 750 points each. If you want to save routes, the 431 can store 50 of them all reversible with up to 300 per route.
When connected with a DSC capable VHF radio, the GPSMAP 431 can graphically display the positioning data received from the radio. Other features include built in tide and celestial data, back up of user data on a data card, and a Housing that is waterproof to IPX-7 standards.Size: 5.7"W x 5.0"H x 2.7"D. One-Year Warranty
