MEGA Down Imaging – NEW to Helix 7
Get unprecedented underwater clarity with coverage down to 125' below your boat. MEGA Down Imaging unlocks new details with up to 3X more output than standard Down Imaging sonar.
Dual Spectrum CHIRP
Know what's below your boat thanks to long, well defined fish arches and a clear view of fish-holding structure and the bottom. Powered by the Low Q CHIRP transducer, Dual Spectrum offers two ways to search – wide mode for maximum coverage and narrow mode for maximum detail.
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, and even watch lure presentations – all at the push of a button.
Humminbird Basemap Built In
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 more. Includes charts of more than 10,000 lakes, plus coastal coverage for the U.S.
Create real-time maps of your fishing spots. Map depth contours, bottom hardness, and vegetation as you drive your boat, with eight hours of built-in recording time.
High-speed Ethernet allows you to build a powerful, professional-grade fishing system. Easily connect multiple fishfinders or upgrade to add-on technologies like Minn Kota i-Pilot Link, 360 Imaging, and CHIRP Radar.
Enable features like wireless software updates from the Humminbird FishSmart App and also keep your phone out of the water and in your pocket by displaying notifications on your Humminbird.
