Overview
Built for anglers who want a large, network-ready display at the helm, this control-head-only unit centers on sonar imaging, charting, and system integration. The 18.5" Full-HD touchscreen pairs with MEGA Imaging+ and Dual Spectrum CHIRP sonar, while included LakeMaster and CoastMaster VX Maps support navigation across a wide range of U.S. and Canadian waters. It also offers NMEA 2000, HDMI In/Out, WiFi, Bluetooth, and One-Boat Network compatibility for tying into other onboard equipment. Because this model does not include a transducer, it suits buyers who want to choose their own transducer or add a second display to an existing Humminbird setup.

Considerations & Trade-offs
- This is a control-head-only model, so you’ll need to choose and add a compatible transducer separately.
- The 18.5" Full-HD touchscreen offers a large information view, but it also takes up substantial helm space compared with smaller displays.
- Advanced networking and One-Boat Network integration are useful if your boat setup can support them; otherwise, some of the system’s capabilities may go unused.
- Included LakeMaster and CoastMaster VX Maps cover over 13,000 lakes, waterways, and coastal waters in the U.S. and Canada, so anglers outside those areas may need different chart coverage.
