Venture offshore with the GPSMAP 492 and its counterpart, the GPSMAP 498 Sounder. With preloaded coastal maps for the U.S., the 492 is ready for action on the seas, right out of the box.
Chart Your Course
This rugged, waterproof chartplotter comes preloaded with BlueChart g2 data for the U.S. coast, including Alaska and Hawaii. This detailed map data includes 3D maps, tide and current data, improved IALA symbols, navaids, marinas, boat ramps and coastal roads. There's even a database of aerial photos, detailed roads and points of interest that you can reference for "real picture" views of harbors and marinas. The 492 can also accept preloaded data cards for additional map coverage.
Connect to Another Plotter
The 492 displays real-time tide and current information, so you can stay aware of changing conditions on the water. It also has Garmin's proprietary CANet® bus, so you can connect to another chartplotter or sounder on your boat to share information.
