The GPSMAP 168 Sounder packs a boatload of features in a sleek unit that won't eat up precious onboard space.

The GPSMAP 168 Sounder is a combination GPS receiver and chartplotter which includes a depth-finder. The unit also contains an impressive list of features including a powerful 12 parallel channel GPS receiver and tide prediction tables. Featuring a built-in worldwide basemap with U.S. highways, interstates, rivers, and lakes, the GPSMAP 168 Sounder also can download up to 2.5 MB of extra map data from Garmin's MapSource® line of CD-ROMs, including Recreational Lakes with Fishing Hot Spots and U.S. Waterways & Lights.

Physically, the unit resembles Garmin's popular Fishfinder 240. It measures about five by six inches in size and boasts a four-level gray FSTN LCD display with 240 x 240 pixels. Even in the dark the unit is easy to read, thanks to a backlit display.

Additionally, the GPSMAP 168 Sounder has a 150-watt depth-finder to make catching fish a whole lot easier. The unit features Garmin's exclusive See-Thru® technology which will help separate fish returns from thermoclines and structure. What's more, a graphic whiteline on the GPSMAP 168 Sounder provides a clear image of both bottom hardness and structure.
