Preloaded and ready for the water
The unit boasts built-in, highly-detailed BlueChart cartography of the coastal United States, including Alaska and Hawaii. This data provides detailed coastlines, shaded depth contours, navaids, port plans, wrecks, restricted areas, and more. Boaters can also purchase pre-programmed data cards of other BlueChart regions, like Canada or the Bahamas, or charts of inland U.S. lakes.
The unit has been updated with a new look and feel that makes marine navigation even easier. Building on Garmin’s popular and proven GPSMAP 182C, the GPSMAP 198C Sounder has a new and brighter display that makes charts incredibly easy to view — even in direct sunlight. The unit also features an updated faceplate.
Designed for easy installation in your boat’s open cockpit or overhead boxes, Garmin’s GPSMAP 198C Sounder helps you chart a clear path to your fishing or boating destination.
In addition to the features mentioned above, the GPSMAP 198C Sounder also has a dual-frequency (50/200 kHz) sonar that outputs 500 watts of power (RMS), or 4,000 watts (peak-to-peak)—for a clear and accurate picture of bottom depth, density, thermoclines, and fish targets.
