Navigate the Lake
The GPSMAP 531s comes ready to go with preloaded U.S. Inland Lake map data. For areas outside the U.S., the GPSMAP 531s has a worldwide basemap with satellite images in place of more traditional maps. The GPSMAP 531s 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.
With the optional Inland Lakes Vision SD card, you can add a whole new dimension of exceptional features to your chartplotter.
