The Humminbird HELIX 7 CHIRP MEGA DI GPS G4N combines MEGA Down Imaging, Dual Spectrum CHIRP sonar, AutoChart Live, an internal GPS, and Humminbird Basemap on a sharp 7" high-definition display. Full networking support — Ethernet, Bluetooth, NMEA 2000, and Wi-Fi — plus One-Boat Network compatibility puts comprehensive boat and fish-finding control at your fingertips.

Features:

• Keypad Control: Softkey controls and a user-friendly menu system let you navigate pre-loaded split-screen views reliably in any conditions.
• MEGA Down Imaging: Delivers underwater clarity to 125 feet below the boat with up to 3× more detail than standard Down Imaging sonar.
• Dual Spectrum CHIRP Sonar: Powered by a proprietary Low-Q CHIRP transducer, this 2D sonar offers Wide Mode for maximum coverage and Narrow Mode for fine detail — giving you clear fish arches and bottom structure before you cast.
• Internal GPS and Humminbird Basemap: Pre-loaded base map covers more than 10,000 lakes plus continental U.S. coastal areas, displaying buoys, day markers, hazards, marinas, contours, and depth markers.
• Premium Chart Compatible: Supports optional Humminbird LakeMaster® and CoastMaster™ charts as well as compatible Navionics® charts for expanded coverage.
• AutoChart Live: Maps depth contours, bottom hardness, and vegetation in real time as you navigate. Includes 8 hours of built-in recording and is compatible with AutoChart Zero Line SD cards for virtually unlimited mapping capacity.
• One-Boat Network Compatible: Seamlessly integrates with Humminbird and Minn Kota products — including Minn Kota i-Pilot Link — to expand boat control and fish-finding capabilities.
• Ethernet Networking: High-speed Ethernet connects multiple fish finders or add-on technologies such as Minn Kota i-Pilot Link and Humminbird CHIRP Radar.
• Bluetooth: Enables wireless control of compatible Talon and Raptor shallow-water anchors, wireless software updates via the Humminbird FishSmart App, and smartphone notification display.
• NMEA 2000 Networking: Built-in NMEA 2000 connectivity integrates boat performance, weather, and water condition data directly on the control head.
• In the Box: Control head, transom-mount transducer, power cable, gimbal mounting bracket, and mounting hardware.
