Master the underwater world like never before with the Humminbird® Helix 12 CHIRP MEGA DI+ GPS G3N GPS Fishfinder/Chartplotter Control Head. This robust Humminbird fish finder sports a spacious, vivid 12.1" display for easy viewing of the powerhouse array of technologies. MEGA Down Imaging+ brings unprecedented underwater clarity down to 200' below your boat. Dual Spectrum CHIRP provides long, well-defined fish arches and a clear view of fish-holding structure and the bottom. Dual Spectrum CHIRP compatibility offers 2 ways to search: wide mode for maximum coverage and narrow mode for maximum detail. SwitchFire Sonar lets you take command of how your sonar returns appear: with 2 display modes, you can add or remove detail; account for water depth, temperature, and turbulence; even watch lure presentations, all at the push of a button. The built-in Humminbird Basemap provides you a clear view of underwater terrain and surrounding points of interest so you can fish and navigate with total confidence. Identify buoys, day markers, hazards, marinas, contours, depth markers, and much, much more. Includes charts of more than 10,000 lakes, plus coastal coverage for the U.S. AutoChart Live creates real-time maps of your fishing spots, with access to patented Humminbird LakeMaster® features. Map depth contours, bottom hardness, and vegetation as you drive your boat. NMEA 2000® Networking connects your HELIX to a NMEA 2000 backbone to gather a complete view of your vessel, including available information like engine gauges, fuel information, and NMEA 2000 connected accessories. Share this information to any other Humminbird unit onboard that is connected via an Ethernet network. Built-in Bluetooth connectivity enables wireless software updates from the Humminbird FishSmart App and also helps you keep your phone out of the water and in your pocket by displaying notifications directly on your Humminbird. Additionally, you can take control of your most-used features with an optional Bluetooth remote (RC2). The Humminbird Helix 12 CHIRP MEGA DI+ GPS G3N GPS Fishfinder/Chartplotter Control Head includes mounting hardware, power cable, and gimbal mounting bracket. Transducer not included.
