Garmin GPSMAP 178c-02

The GPSMAP(R) 178C Sounder is a new-generation fully integrated chartplotter and powerful sonar, offering the same brilliant sunlight-readable color LCD, powerful features, and simple interface as the GPSMAP 172C-all in a compact, value-priced console that leaves fish nowhere to hide. It comes standard with a built-in worldwide marine basemap and accepts MapSource(R) BlueChart(R) offshore marine cartography-featuring detailed depth contours, inter-tidal zones, wrecks, navaids, and many other points of interest. For small-water anglers, the GPSMAP 178C Sounder is compatible with MapSource Recreational Lakes with Fishing Hot Spots-featuring fishing areas, boat ramps, marinas, and hazards for hundreds of popular U.S. and Canadian lakes. Pre-programmed data cards can be easily inserted into the slot on the front of the unit.
