The
GPSMAP® 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® BlueChart®
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.
