Minimizes heading error, course deviation, rudder movement and power consumption, while providing a comfortable ride
Minimal commissioning and calibration
Designed for boats less than 30 feet long, the GHP Compact Reactor Hydraulic Autopilot provides relief from manually holding the wheel to maintain course, especially when cruising at moderate to high speeds¹. Sit back at the helm, and enjoy your time on the water as the solid-state 9-axis AHRS technology delivers a comfortable ride.
Offered in 3 different corepacks, this autopilot lets you configure your autopilot setup depending on the features you need and how much you want to spend. Buy the starter pack (compatible chartplotter required)², add a GHC™ 20 marine autopilot control unit, or add both a GHC 20 and Shadow Drive.
Easy-to-install with flexible mounting options and quick, easy commissioning. Choose corepack with Garmin patented Shadow Drive and simply turn the wheel to take control of the helm; hold a constant course to re-engage. Integrates with compatible Garmin electronics to control the autopilot from the chartplotter display. Can be engaged to follow an Auto Guidance path³ (requires LakeVü HD Ultra maps or BlueChart® g2 Vision® HD charts).
Solid-state 9-axis Attitude Heading Reference System
With its advanced solid-state 9-axis AHRS, the GHP Compact Reactor provides you more flexible mounting options. In addition, this new system greatly minimizes heading error, course deviation, rudder movement and power consumption, while providing a comfortable ride for all onboard.
Reacts to Conditions
This amazing autopilot actually reacts to the sea to hold your course. Even when the boat is pitching and rolling, you can remain confident that the GHP Compact Reactor autopilot will keep you on your desired course.
Minimal Commissioning and Calibration
All autopilots require commissioning and calibration to work properly. We know you just want to get on the water, so we made this process as fast and easy as possible. That’s the power of simple.
Full Integration with Garmin Electronics
Combined with compatible Garmin networked electronics, you can have full control of the GHP Compact Reactor from wherever you are on the boat. In addition to holding its course in virtually all weather and wind conditions, the system can smoothly perform a variety of pre-programmed trolling and search procedures. Plus, with BlueChart g2 Vision HD charts (sold separately), you gain optional features like Auto Guidance, which automatically steers GPS paths.
Stay in Control with Shadow Drive Technology
Included patented Shadow Drive technology gives you the security of knowing you maintain control even when the autopilot is engaged. The Shadow Drive system automatically disengages the autopilot if the helm is turned, giving you the freedom to maneuver the boat. The autopilot automatically re-engages when you hold a steady course.
Connect to Networked Devices
The GHP Compact Reactor Autopilot can be operated using the included GHC 20 helm control unit. In fact, you can connect up to 3 GHC helm control units. You can also operate it directly from your compatible Garmin chartplotter¹ screen. The GHC communicates with the autopilot system via your NMEA 2000® network, so autopilot-heading data can be shared easily with other devices. This enables MARPA and chart overlay when connected to a Garmin radar and chartplotter. An optional handheld wireless remote control is also available.
¹Not recommended for fishing, or applications that require holding heading while trolling or at low speeds. For applications that require precise heading control while trolling or at low speeds, our higher-performance GHP Reactor models are recommended. ²Requires a Garmin echoMAP™ CHIRP 5x, 7x or 9x chartplotter/sonar combo or GPSMAP® 7400, 7600, 8000, 8200, 8400, 8500 or 8600 series chartplotter ³Auto Guidance is for planning purposes only and does not replace safe navigation operations.
