Garmin GPSMAP® 492 GPS Receiver

The Garmin GPSMAP 492C gives you the cartography you need to venture offshore. These versatile units come ready to launch with preloaded marine map detail utilizing the new BlueChart g2 technology. Coverage is for U.S. coastal areas, including Alaska and Hawaii. Features include integrated mapping, 2D or 3D map perspective, tide and current data, improved IALA symbols, navaids, marinas, boat ramps, roads, and more. Both units accept preprogrammed data cards for loading additional map coverage of inland lakes or BlueChart detail for other regions. And the GPSMAP 498C's built-in 500-watt (RMS) sounder features Ultrascroll for high-speed screen updates, with the proprietary Garmin CANet bus enabling sounder display information to be shared with, and controlled from, another chartplotter on your boat.
