The Humminbird HELIX 7 GPS CHIRP SI G4 brings together CHIRP Side Imaging, CHIRP Down Imaging, Dual Spectrum CHIRP Sonar, AutoChart Live, internal GPS, and Humminbird Basemap in a single unit built around a 7" high-definition 1024x600 display. Softkey controls make it straightforward to cycle through the many pre-loaded split-screen view options, while compatibility with LakeMaster, CoastMaster, and Navionics charts keeps your options open on any water.

Dual Spectrum CHIRP 2D sonar — powered by a Low-Q CHIRP transducer — lets you toggle between Wide Mode for broad coverage and Narrow Mode for fine detail. CHIRP Down Imaging cuts through noise to reveal structure directly beneath the hull, and CHIRP Side Imaging extends that clear picture out to 800 ft side-to-side. AutoChart Live lets you build real-time depth, bottom-hardness, and vegetation maps as you run, with eight hours of built-in recording and support for AutoChart Zero Line SD cards for virtually unlimited mapping capacity. The built-in Humminbird Basemap covers more than 10,000 lakes plus continental U.S. coastal waters, including buoys, day markers, hazards, marinas, contours, and depth markers.
