Fishfinder with 5" colour screen. Combines CHIRP Sonar with DownScan Imaging which produces a near photographic image of fish-holding structures beneath the boat. CHIRP sonar's increased sensitivity, better sonar resolution and interference suppression provide for a clearer image of both bait and game fish. Multi-window display. Easily selectable frequency settings. Advanced Signal Processing (ASP) for reducing the amount of manual adjustments. TrackBack allows for viewing recorded sonar history.
