The hydraulic Compact Reactor 40 automatic guidance system designed for boats under 9 meters in length (sub 30-footers) releases you from holding the wheel to maintain the correct direction in reasonable or high speeds. Focus on enjoying your time on the water as the 9-axis Solid-state AHRS technology ensures an enjoyable sailing experience.
The automatic guidance system is available in three different basic configurations, where you can choose the desired features based on requirements and cost. Purchase the starter kit (requires a compatible chart plotter) and add the GHC™ 20 automatic guidance control unit and/or the Shadow Drive™.
The automatic guidance system is easy to install, has flexible mounting options, and be commissioned quickly and easily. Choose the basic kit and the patented Shadow Drive and take the wheel simply by turning it. You can re-engage the automatic guidance system by holding a direction. The system integrates with compatible Garmin devices so that the automatic guidance can be controlled via the screen of a chart plotter. In addition, it can also be set to follow an automatic guidance route (requires the use of BlueChart® g2 Vision® HD charts).
Solid-state 9-axis AHRS
With its advanced solid-state 9-axis AHRS, Compact Reactor 40 provides you with more flexible mounting options. In addition, this new system greatly minimizes heading errors, course deviation, rudder movement and power consumption while providing a comfortable ride for all on board.
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 Compact Reactor 40 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 our compatible networked electronics, you can have full control of Compact Reactor 40 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 preprogrammed trolling and search procedures. Plus, with BlueChart g2 Vision HD charts (sold separately), you gain optional features such as Auto Guidance³, which automatically steers GPS paths.
Stay in Control with Optional Shadow Drive Technology. The Compact Reactor 40 autopilot supports optional patented Shadow Drive technology. This 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.
Compact Reactor 40 can be operated directly from your compatible Garmin chartplotter¹ screen or by using up to 3 GHC helm control units. 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 chart plotter. An optional handheld wireless remote control is also available.
