Venture offshore with the GPSMAP 498 Sounder and its counterpart, the GPSMAP 492. With a powerful built-in sounder and preloaded coastal maps for the U.S., the 498C is ready to handle any offshore fishing adventure.
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, coastal roads and more. 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 498 can also accept preloaded data cards for additional map coverage.
Catch Some Fish
The 498 comes with a built-in 500-watt (RMS) sounder with enough power to track fish deep underwater, yet precise enough to perform well in shallow water as well. The sounder features Ultrascroll® for high-speed screen updates and can show both the sonar and map on the screen at the same time. And, it can even connect to another chartplotter with Garmin's proprietary CANet® connection.
