The Humminbird HELIX 7 CHIRP MEGA DI GPS G4N CHO is a control-head-only fish finder built around MEGA Down Imaging, Dual Spectrum CHIRP Sonar, AutoChart Live, an internal GPS, and Humminbird Basemap. Control head only — no transducer included. Choose a transducer to suit your install, or connect to a compatible Minn Kota trolling motor. The 7-inch high-definition display supports multiple pre-loaded split-screen view options, and all G4N networking features — Ethernet, Bluetooth, NMEA 2000, and Wi-Fi — are standard. Designed to connect to Built-in MEGA Down Imaging or Universal Sonar 2 on Minn Kota trolling motors, or to slot into an existing Humminbird Ethernet network, this unit delivers a full-featured sonar and mapping platform without redundancy.

Features:

• Control Head Only (CHO): No transducer included. Intended for use with Built-in MEGA Down Imaging or Universal Sonar 2 on compatible Minn Kota trolling motors, or for adding to an existing Humminbird Ethernet network.
• Keypad Control: Softkey controls and a user-friendly menu system provide reliable, button-based operation in any on-water condition.
• MEGA Down Imaging: Delivers underwater imaging down to 125 feet with up to 3X more detail than standard Down Imaging sonar.
• Dual Spectrum CHIRP Sonar: Powered by a Low-Q CHIRP transducer, this 2D sonar mode offers Wide Mode for broad coverage and Narrow Mode for fine detail, producing clear fish arches and defined bottom structure.
• Internal GPS and Humminbird Basemap: Built-in GPS pairs with a base map covering more than 10,000 lakes plus continental U.S. coastal areas, including buoys, day markers, hazards, marinas, depth contours, and points of interest.
• Premium Chart Compatible: Supports optional Humminbird LakeMaster® and CoastMaster™ charts, as well as compatible Navionics® charts.
• AutoChart Live: Generates real-time depth-contour, bottom-hardness, and vegetation maps as you navigate. Includes 8 hours of built-in recording time; compatible with AutoChart Zero Line SD cards for expanded capacity.
• One-Boat Network Compatible: Integrates with Humminbird and Minn Kota products to enable coordinated boat control and fish-finding features across a connected system.
• Ethernet Networking: High-speed Ethernet supports multi-unit fish finder networks and add-on technologies such as Minn Kota i-Pilot Link and Humminbird CHIRP Radar.
• Bluetooth: Wireless connectivity for compatible Talon and Raptor shallow water anchors, wireless software updates via the Humminbird FishSmart App, and smartphone notification display.
• NMEA 2000 Built-In: Connects to an accessory NMEA 2000 network to pull in boat performance, weather, and water condition data.
• Wi-Fi: Onboard Wi-Fi supports app connectivity and wireless functionality within the One-Boat Network ecosystem.
