If fishing is in your DNA, there's no such thing as "too early" or "too far." High expectations go with the territory. The Humminbird Helix 8 CHIRP MEGA DI G3N GPS/Fishfinder features an 8inch display, MEGA Down Imaging and Dual Spectrum CHIRP Sonar. Includes GPS mapping, built-in Bluetooth, Ethernet networking capabilities, AutoChart Live with depth, vegetation and bottom hardness mapping. Top it all off with Humminbird Basemap built-in.
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
Traditional sonar at it's absolute best. 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.
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.
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.
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.
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).
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.
Humminbird provides even more map options thanks to additional Navionics compatibility. Available maps regions include detailed cartography for saltwater and freshwater applications which make Navionics a great option for fishing, cruising or sailing.
