The M68C is a high-performance, affordable unit with remarkable fishfinding and plotting capabilities on a 3.5" diagonal, 256-color, active matrix TFT display. The simplified keypad is backlit for night and low-light operations. The M68C uses an advanced, internal GPS/WAAS receiver antenna that positions you on a built-in, high-detail hydrographic map. This mapping of lakes, rivers, and U.S. coastal waters comes complete with navaids. As a fishfinder the 100-watt RMS, low-profile transom-mount 50/200 kHz transducer generates an accurate return down to 600'. The transducer has a built-in surface temp sensor and will operate at speeds up to 70 mph. The M68C uses a full color digital LCD flasher display with COLORLINE to separate fish and structure from the bottom returns. The space-saving case design offers an adjustable tilt, quick-mount/release, and fast connect/disconnect cable. 5.8"H x 4.3"W x 2.5"D. One-year warranty.
