Humminbird HELIX 15 CHIRP MEGA SI+ GPS G4N CHO Display Only

The Humminbird HELIX 15 CHIRP MEGA SI+ GPS G4N CHO is a 15.4-inch control-head-only unit for anglers who already have a compatible transducer or are planning a custom Humminbird installation. MEGA Side Imaging+, MEGA Down Imaging+, Dual Spectrum CHIRP, internal Precision GPS, and AutoChart Live provide advanced charting and sonar functions, while NMEA 2000, Ethernet, Bluetooth, and WiFi support a connected system.

Who Is This For?

This control head suits large fishing boats, tournament rigs, multi-display helms, and owners replacing a Humminbird display while retaining or separately selecting the transducer. Its size is useful when sonar and chart information must remain visible at the same time.

It is not ideal for small boats or buyers who want a complete ready-to-install bundle. The transducer is not included, and the 15.4-inch display requires substantial dash space.

Warranty & Support

Humminbird provides a 2-year limited warranty. The supplied specifications do not state warranty exclusions or service procedures.

The HELIX 15 SI+ CHO is the control-head alternative to the bundled HELIX 15 SI+ G4N, offering the same 15.4-inch display class and network features without including a transducer. That makes it suitable for a planned replacement or custom transducer installation, but it shifts compatibility and additional hardware selection to the buyer. Choose it when you need a very large Humminbird display and already have a sonar plan.
