HELIX® 7 CHIRP MEGA DI Fishfinder/GPS Combo G3 with Navionics+ & Transom Mount Transducer

The HELIX 7 CHIRP MEGA DI GPS G3 NAV+ fish finder features MEGA Down Imaging, Dual Spectrum CHIRP Sonar, AutoChart Live, GPS and Humminbird Basemap built-in. The 7", ultra-wide display gives you ample room to view the many pre-loaded split screen view options. This unit is preloaded with Navionics+ chart data for the U.S. and Canada, including over 21,000 lakes. 


  • Includes Navionics+ (U.S. and Canada) map information pre-loaded on the unit for out-of-the-box coverage of over 21,000 lakes and waterbodies.
  • HELIX 7- MEGA Down Imaging: Get unprecedented underwater clarity with coverage down to 125 feet below your boat. You'll unlock new details with up to 3X more output than standard Down Imaging sonar.
  • Dual Spectrum CHIRP: Before you cast, know what's down there thanks to long, well-defined fish arches, and a clear view of fish-holding structure and the bottom. Powered by our proprietary, Low Q CHIRP transducer, Dual Spectrum offers two ways to search: wide mode for maximum coverage and narrow mode for maximum detail.
  • SwitchFire Sonar: Take command of how your sonar returns appear. With two 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.
  • Humminbird Basemap Built-in: Our enhanced standard basemap provides you with 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: Create 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, with eight hours of built-in recording time.
  • LakeMaster Compatible: Upgrade to the unrivaled accuracy and detail of Humminbird LakeMaster maps. From easy-to-read contours, to highlighted depth ranges, to scrollable lake lists, you'll have all the tools you need to make every moment count
