Imagine gliding across the water, your boat humming softly as the sun rises, and suddenly, the screen lights up with razor-sharp images of fish schools darting around submerged structures. That's the power of the Humminbird HELIX 8 CHIRP MEGA SI+ GPS G4N CHO at your fingertips. This control head only unit delivers pro-level performance without the transducer, giving you the freedom to customize your setup for any fishing style—from trolling deep reservoirs to chasing bass in shallow bays.
At the heart of this fish finder lies MEGA Side Imaging+ and MEGA Down Imaging+, pushing the boundaries of what's visible beneath the surface. Side Imaging+ scans up to 200 feet on each side of your boat with 20% more detail and 60% greater range than standard MEGA Imaging. Spot hidden cribs, drop-offs, or weed edges that hold trophy fish, all in stunning real-time motion with MEGA Live.
Down Imaging+ dives straight below, revealing fish and structure down to 200 feet with incredible precision. Forget fuzzy returns—see individual baitfish separating from predators, helping you decide exactly where to drop your line.
Dual Spectrum CHIRP gives you two sonar modes in one: Wide Mode sweeps massive coverage for locating fish fast, while Narrow Mode pinpoints the finest details on structure and bottom composition. Powered by advanced Low-Q CHIRP technology, it paints vivid fish arches and reveals bottom hardness, so you know if that mark is a rock pile or a muddy flat loaded with walleye.
Precision GPS tracks your position down to the inch, marking hotspots with up to 2,750 waypoints. The Humminbird Basemap covers over 10,000 freshwater lakes and U.S. coastal areas, highlighting contours, hazards, marinas, and depth markers for confident navigation.
Take it further with AutoChart Live—map contours, hardness, and vegetation in real-time as you motor around. Store eight hours onboard or expand with Micro SD cards. Pair with premium charts for scrollable lake lists and highlighted depths that turn any water into your personal fishing atlas.
This CHO model shines in networked setups. Ethernet lets you daisy-chain multiple units or add radar and i-Pilot Link for trolling motors. Bluetooth connects to shallow water anchors and downriggers for wireless control, plus smartphone notifications and updates via the FishSmart app. NMEA 2000 pulls in boat data, weather, and more, while Wi-Fi enables seamless sharing.
Perfect for Minn Kota owners—plug into built-in MEGA Imaging trolling motors or add MEGA 360 for 360-degree views. Share sonar across your fleet for tournament-winning intel without extra heads.
The CHO design means no bundled transducer, so you select exactly what fits your boat and water type. Existing Humminbird owners can network in effortlessly. Keypad controls keep operations simple even with gloves on or in rough seas—soft keys and intuitive menus get you to views fast.
Waterproof build, 8-inch high-res LCD (1024x600), and compact dimensions (12" x 7" x 4.13") make mounting a breeze with the included gimbal bracket and power cable.
CHO stands for Control Head Only, meaning it arrives without a transducer. This lets you choose the perfect transducer for your boat, like those with Minn Kota built-in MEGA Imaging or add-ons such as MEGA 360.
MEGA Side Imaging+ extends up to 200 feet on either side of your boat, delivering 20% more detail and 60% more range than standard MEGA Side Imaging for spotting distant structure.
