The Humminbird Helix 7 GPS CHIRP MSI G4N brings together MEGA Side Imaging, MEGA Down Imaging, Dual Spectrum CHIRP Sonar, AutoChart Live, an internal GPS, and Humminbird Basemap in a single unit. A high-definition 7-inch display renders multiple pre-loaded split-screen views with clarity, while Ethernet networking, Bluetooth, NMEA 2000, and One-Boat Network compatibility give you full control of your electronics from one place. Softkey controls let you navigate the menu system reliably in any conditions, and the included XNT 9 HW MSI 150 T transducer means you can get on the water without additional purchases.

CHIRP Digital Sonar processing sharpens both Side Imaging and Down Imaging returns, filtering noise so fish and structure appear with greater definition to the sides and directly beneath your boat. Dual Spectrum CHIRP 2D sonar operates in Wide Mode for broad coverage or Narrow Mode for pinpoint detail, powered by Humminbird's Low-Q CHIRP transducer. The built-in basemap covers more than 10,000 lakes plus continental U.S. coastal areas, including buoys, day markers, hazards, marinas, contours, and depth markers. Optional LakeMaster, CoastMaster, and Navionics charts expand coverage further. AutoChart Live lets you build real-time depth contour, bottom hardness, and vegetation maps as you move across the water, with eight hours of built-in recording time and compatibility with AutoChart Zero Line SD cards for virtually unlimited mapping capacity.
