Master the underwater world like never before with the Humminbird® HELIX 7 CHIRP MEGA DI GPS G3 GPS Fishfinder/Chartplotter. This robust Humminbird fish finder sports a spacious, vivid 7" display for easy viewing of the powerhouse array of technologies. MEGA Down Imaging brings unprecedented underwater clarity down to 125' below your boat. Dual Spectrum CHIRP provides long, well-defined fish arches and a clear view of fish-holding structure and the bottom. Powered by the proprietary, Low Q CHIRP transducer, Dual Spectrum CHIRP 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. Share this information to any other Humminbird unit onboard that is connected via an Ethernet network. The Humminbird HELIX 7 CHIRP MEGA DI GPS G3 GPS Fishfinder/Chartplotter includes the transducer, mounting hardware, power cable, and gimbal mounting bracket.
