Designed for boats less than 30 ft long, the Compact Reactor 40 hydraulic autopilot provides relief from manually holding the wheel to maintain course, especially when cruising at moderate to high speeds. 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 chart plotter required), add a GHC 20 marine autopilot control unit, or add both GHC 20 and the Shadow Drive™ attachment. The autopilot is easy to install with flexible mounting options and quick, easy commissioning. Choose a corepack with our patented Shadow Drive technology, and simply turn the wheel to take control of the helm, hold a constant course to re-engage. It integrates with compatible Garmin electronics to control the autopilot from the chart plotter display. And it can be engaged to follow an Auto Guidance path (requires LakeVu g3 maps or BlueChart® g3 charts).
