Product Description
humminbird The Humminbird 581i HD DI Fishfinder Chartplotter Combo offers best-in-class HD screen resolution with timber, rocks, and even fish taking shape on a 5" crystal-clear monochrome display. Down Imaging Sonar with DualBeam PLUS with Switchfire creates detailed images with high-frequency sound waves emitted in ultra-thin slices. The sonar returns from these waves produce a "snapshot" of what's below your boat and are sensitive enough to track a jig down to 70' and separate fish as close as 2.5" apart. Internal GPS and built-in UniMap let you pinpoint your location, and an SD card slot allows for upgrading to LakeMaster or Navionics cartography. The 581i HD DI Fishfinder Chartplotter feature the convenient Tilt and Swivel Disconnect Mounting System. Measures 7.25"W x 7"H x 4"D.
