GARMIN GPSMAP 178 Sounder
Discontinued

The GPSMAP 178 has GPS navigation, marine chartplotting, and sonar in one compact package. This combination chartplotter/sounder includes the same user-friendly interface as its colour counterpart, the GPSMAP 178C, but has a high-resolution monochrome display and a lower price. The GPSMAP 178 has a built-in worldwide marine basemap, state-of-the art processor with fast map redraw, and sunlight readable, 10-level grayscale display in a waterproof, space-saving console.

• Simple keypad with backlighting for easy operation
• One knob, adjustable tilt and swivel mount so you can quickly pop it in and out
• Front loading data cards for easy access

Users can enhance basemap detail on the GPSMAP 178 by simply plugging in data cards preprogrammed with BlueChart or Fishing Hot Spots detail or downloading data from optional MapSource CDs to an optional Garmin data card. BlueChart provides offshore marine coverage that includes shaded depth contours, navaids, shoreline, and more. For inland boating and fishing, the U.S. Recreational Lakes with Fishing Hot Spots CD & preprogrammed data cards are packed with inland lake maps, profiles, marinas, fishing areas and useful outdoor resources. The GPSMAP 178 is available with either a single or dual-frequency transducer making it the perfect companion for offshore or inland lake fishing. Boaters can choose dedicated full-screen map, full-screen sonar, split-screen map/sonar, compass, and navigational screens - with customizable digital data fields for each page.
