Help make your next ice fishing adventure more successful with the ICE 688ci Combination GPS/Sonar Fishfinder from Humminbird. Get all the information you need to find fish using this fishfinder's internal GPS antenna, built-in cartography, and advanced sonar. A 5" color screen with LED backlight allows you to display mapping or depth information. In addition to the display unit, this fishfinder comes complete with a tilt and swivel mount, an ice transducer and float, battery and charger, and a carrying bracket and bag to haul it all out on the hard water.

This combo features a peak to peak power output of 4000W so you can read bottom in up to 1500'. The transducer utilizes two coverage angles of 20° & 60° at -10db, so you can adjust coverage from narrow to wide, based on angling conditions. SwitchFire technology allows you to choose between clear and max modes, so you can select the level of sonar returns displayed. Dynamic zoom provides 2 times magnification on the view of a depth range of your choosing so you can key in on certain areas. Ice target line allows you to select the exact depth of any point on the flasher readout so you can know exactly where the fish are.

Mark your most productive holes and easily return to them using the unit's internal GPS antenna and chart plotting capabilities. The built-in Unimap cartography covers the contiguous US coastline, as well as inland lakes and rivers on maps with 30-meters per-pixel resolution. This unit features a 32GB SD card slot, which allows you to save screenshots, sonar recordings, and waypoints for future reference.
