The GHC 10 is the dedicated control unit for the GHP 10 and GHP 12 autopilot systems.

Handle your Boat with Convenience and Safety

The simple, interactive interface of the GHC 10 gives boaters the confidence and security of controlling the heading of the boat at the press of a key. For example, each press of the steering soft key will change the commanded heading of the autopilot by 1 ?. And as a safeguard, a dedicated Standby key allows you to instantly place the autopilot in standby to keep it from re-engaging.

Connect to other Marine Units

The GHC 10 communicates with the GHP 10 and GHP 12 autopilot systems via a NMEA 2000 bus, so autopilot heading data easily can be shared with other devices.

The GHC 10 also has the capability of communicating to a chartplotter for GPS-enabled route guidance over NMEA 2000 or NMEA 0183.
