The HELIX® 10 Mega SI won Best in Show at ICAST for the sixth consecutive Humminbird® electronics award. The Humminbird HELIX 10 Mega SI G2N GPS Fishfinder and Chartplotter improves on the award-winning formula. Its brilliant 10.1" screen with 1,500-nit brightness allows easy viewing even indirect sunlight. Patented Humminbird Side Imaging® range now extends to a full 400' either side of the boat for 800' of side-to-side coverage, revealing even more key structures and fish. Powerful CHIRP SONAR allows the unique selection of Low, Medium, and High frequency ranges, giving clean returns and exceptional target separation. Down Imaging® brings crystal-clear returns to depths of 250', and SwitchFire® SONAR with depths of 600' shows intricate details of bottom and structures. Side-by-side presentation of Down Imaging and SwitchFire SONAR delivers ideal vertical viewing for fishing, actively showing your lure and fish for perfect preparation. A built-in, high-sensitivity GPS receiver provides pinpoint location accuracy, with storage capacity for up to 2,500 waypoints, 45 routes, 50 tracks, and 20,000 track points. Dual card slots empower compatible cartographies like Humminbird LakeMaster®/PLUS, Humminbird SmartStrike™, Navionics+, HotMaps™ and Platinum+™, Humminbird AutoChart® and AutoChart PRO™. Ethernet connection gives access to expansion technologies like HD RADAR, NMEA 2000®, AIS, and 360 Imaging®.
