Navigate the Lake
The GPSMAP 431 comes ready to go with preloaded U.S. Inland Lake map data. For areas outside the U.S., the GPSMAP 431 has a worldwide basemap with satellite images in place of more traditional maps. The GPSMAP 431 also comes standard with a high-sensitivity GPS receiver for superior satellite tracking and quicker acquisition times. And with an SD card slot, it’s easy to add additional maps without connecting to a computer.
Add Sonar
Where applicable, the sounder version, GPSMAP 431s, comes with a powerful dual-beam transducer that clearly illustrates depth contours, fish targets and structure whether you’re fishing in freshwater or off the coast. The GPSMAP 431 and GPSMAP 431s are also NMEA 0183-certified for easy connectivity with sensors, instruments and future marine offerings.
