Features and specifications
Humminbird HELIX 10 CHIRP MEGA SI+ GPS G4N CHO Fish Finder Control Head
MEGA Side Imaging+, MEGA Down Imaging+, Dual Spectrum CHIRP, GPS & Ethernet Networking
The Humminbird CHIRP MEGA SI+ GPS G4N CHO is a professional-grade fish finder control head designed for anglers who want advanced sonar, GPS navigation, mapping, and network connectivity without purchasing an additional transducer. This Control Head Only (CHO) model is ideal for connecting to compatible built-in MEGA Imaging systems, accessory transducers such as MEGA 360 Imaging, or an existing Humminbird Ethernet network.
Featuring a large 10.1-inch display, the unit delivers detailed underwater imaging through MEGA Side Imaging+, MEGA Down Imaging+, and Dual Spectrum CHIRP sonar. Its internal GPS and enhanced Humminbird Basemap provide detailed navigation information, while AutoChart Live allows you to create real-time maps of your fishing areas.
High-speed Ethernet networking and One-Boat Network compatibility make the unit expandable into a larger fishing system, allowing compatible Humminbird, Minn Kota, and Cannon equipment to communicate and share information.
