One piece of must-have gear is the ICE HELIX 7 CHIRP GPS G2. It's an easy-to-use fish-finding machine, delivering the biggest and brightest screen of any ice fishing combo unit to date. Included is Humminbird's new Basemap and CHIRP SONAR. A high-speed LCD digital read-out shows your exact depth, as well as a latency-free digital flasher and customizable graph view with up to 8-times zoom. Precision GPS helps you find and return to productive spots, while optional Humminbird LakeMaster charts provide more detail than any other map on ice.
