Offering access to premium technologies that have previously been reserved for Humminbird’s larger units, the Humminbird Helix 7 CHIRP G3 Sonar gives angler the ability to use MEGA Side Imaging (select models), MEGA Down Imaging (Select models), 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.
MEGA Side Imaging (select models) – See the world below like never before with crystal clear viewing out to 125-feet on either side of your boat. You’ll unlock new detail with up to 3X more output than standard Side Imaging sonar.
MEGA Down Imaging (select models) – Get unprecedented underwater clarity with coverage down to 125-feet below your boat. You’ll unlock new detail with up to 3X more output than standard Down Imaging sonar.
Navionics+ (Select Models) – Map information pre-loaded on the unit for out-of-the-box coverage of over 21,000 lakes and water bodies.
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 Humminbird’s 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 presentation – all at the push of a button.
Humminbird Basemap Built–in – Humminbird’s 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..
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 you boat, with eight hours of built-in recording time.
Ethernet Networking (Select Models ) – High-speed Ethernet allows you to build a powerful, professional-grade fishing system. Easily connect multiple fish finders, or upgrade to add-on technologies, like Minn Kota i-Pilot Link, 360 Imaging, and CHIRP radar.
Bluetooth (Select Models) – 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. Additionally, you can take control of your most-used features with an optional Bluetooth remote (RC2).
