Our Most Responsive Autopilot System on the Water

• Solid-state 9-axis Attitude Heading Reference System (AHRS)
• Minimizes heading error, course deviation, rudder movement and power consumption while providing a comfortable ride
• Minimal commissioning and calibration

Reactor 40 for steer-by-wire provides robust autopilot capabilities for Yamaha Helm Master systems. With a complete package designed for powerboats and sailboats, Garmin brings an advanced marine technology to the boating public that was once only available for commercial boats. The Reactor 40 autopilot series is simply the most responsive autopilot system we have ever offered.

Reactor 40 autopilots are very versatile. Both powerboat and sailing features are available in all corepacks, including heading hold, wind hold, tack/jibe, step turns and more.

Solid-state 9-axis AHRS

With its advanced solid-state 9-axis AHRS, you can mount Reactor 40 nearly anywhere, in any orientation. In addition, this new system greatly minimizes heading error, 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 Reactor 40 autopilot will keep you on your desired course.

Minimal Commissioning and Calibration

All autopilots require commissioning and calibration — all of them. 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 Chartplotters

Combined with a compatible Garmin networked chartplotter, you can have full control of 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 a compatible Garmin networked chartplotter and BlueChart® g2 Vision® charts (sold separately), you gain optional features such as Auto Guidance¹, which automatically steers GPS paths.

Connect to Networked Devices

The Reactor 40 autopilot is operated 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 chartplotter. An optional handheld wireless remote control is also available; however, for the highest level of convenience, control the using a compatible quatix® 3 or quatix 5 marine multisport smartwatch.

¹Auto Guidance is for planning purposes only and does not replace safe navigation operations.

The GHC 20 autopilot helm controller is compatible with newer Garmin autopilots as well as legacy models on both power and sail vessels.

It's large, bright 4-inch color display is easy to read at a distance and 170 degree viewing angle. Glass-bonded anti-glare lens prevents fogging and increases contrast. Daylight readability is enhanced with a high-contrast color scheme. For enhanced night visibility, you have a choice of red/black, green/black or the normal night mode color scheme along with a dimmer control.

An optional handheld wireless remote control is available; however, for the highest level of convenience, control the GHC 20 using quatix, the world’s first marine GPS navigation watch featuring ANT® wireless technology. Power is supplied by the NMEA 2000® network. Included are 2 trim snap piece cover options which allow you to match the GHC 20 with the new GPSMAP® 500/700 series, GPSMAP 8000 Glass Helm series or legacy Garmin chartplotters.
