Humminbird HELIX 7 Chartplotter CHIRP MEGA DI G4N Control Head Only

Overview

Built for anglers upgrading an existing Humminbird Ethernet network or connecting to a Minn Kota trolling motor with built-in MEGA Down Imaging. If you're already networked or adding a second screen to your boat, this control head pairs with the sonar tech already deployed on your motor or primary unit.

This is the display and brains without the transducer. You get a 7-inch high-definition screen, Dual Spectrum CHIRP sonar access, MEGA Down Imaging capability, internal GPS, and full networking support — all the tools to read what's below and navigate with confidence. It's purpose-built for serious anglers who want to expand their sonar without duplicating hardware.

Key Features

• MEGA Down Imaging — produces photographic-quality images of structure below your boat down to 125 feet — you'll see the difference between a brush pile and a school of suspended fish at a glance, with up to 3X more detail than standard imaging.
• Dual Spectrum CHIRP Sonar — highly detailed fish arches and clear views of structure and bottom composition — Wide Mode gives maximum coverage; Narrow Mode locks in on fine detail when you need precision.
• 7-Inch High-Definition Display — 1024 x 600 pixel matrix gives you crisp, readable sonar in direct sunlight and splits eight different pre-loaded screen view options without losing clarity.
• Internal GPS and Humminbird Basemap — built-in navigation with contours, depth markers, and points of interest across 10,000+ lakes and U.S. coastal coverage — fish and navigate with total confidence.
• AutoChart Live — create real-time depth and bottom-hardness maps of your fishing water as you run your boat; comes with eight hours of recording built-in, expandable with optional SD cards.
• Ethernet Networking — plug into your existing Humminbird or Minn Kota network for high-speed data sharing across multiple screens, radar, and compatible shallow water anchors.
• Bluetooth Connectivity — wireless control of compatible Talon and Raptor anchors, plus wireless software updates and smartphone notifications direct to your screen.
• NMEA 2000 Support — connect to external NMEA networks for real-time boat performance, weather, and water condition data all on one display.
• Keypad Control — softkey-operated menu system keeps you operating reliably in rough conditions without touchscreen distractions.
