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

The Humminbird HELIX 15 CHIRP MEGA DI+ GPS G4N CHO is a 15.4-inch control-head-only display for anglers who want a large Humminbird chartplotter and fishfinder platform without a bundled transducer. MEGA Down Imaging+, Dual Spectrum CHIRP, and a 1280 x 800 screen provide a large working area, while NMEA 2000, Ethernet, Bluetooth, and WiFi support broader system connections. Humminbird Basemap is preloaded for basic mapping.

Key Features

- 15.4-inch HD widescreen display – Provides a large chart and sonar workspace for a multi-panel fishing helm.
- 1280 x 800 resolution – Shows clear mapping and sonar information across the large display.
- MEGA Down Imaging+ and Dual Spectrum CHIRP – Supports detailed downward imaging and conventional fishfinding with a compatible transducer.
- NMEA 2000, Ethernet, Bluetooth, and WiFi – Provides confirmed wired and wireless options for a connected installation.
- Humminbird Basemap – Provides basic preloaded mapping without claiming detailed regional chart coverage.

Who Is This For?

This unit suits large fishing boats, multi-display helms, and Humminbird owners who already have a compatible transducer or want to select one for a particular hull installation. The large display is helpful when chart, sonar, and system data must be visible together.

It is not suitable for a small console or a buyer looking for a complete package with transducer included. The control head requires additional sonar hardware before its imaging functions can be used.

Compatibility

Confirmed interfaces include NMEA 2000, Ethernet, Bluetooth, WiFi, and Humminbird Basemap. The supplied information does not identify a specific compatible transducer, NMEA 0183, radar, autopilot, or third-party chartplotter. No named incompatible system was provided; verify Humminbird transducer and network requirements before installation.

The HELIX 15 DI+ CHO is the display-only alternative to the HELIX 15 SI+ CHO and the bundled HELIX 15 SI+ G4N. It retains the 15.4-inch 1280 x 800 screen and broad networking but focuses on MEGA Down Imaging+ rather than Side Imaging+. Choose it when downward imaging is sufficient and you want to select the transducer separately; choose the SI+ model if side-looking sonar is required.
