Designed for boats less than 30 ft long, the GHP Compact Reactor 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 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 chart plotter display. Can be engaged to follow an auto guidance path (requires LakeVu HD Ultra maps or BlueChart® g2 Vision® HD charts).
