Description
Choose your kit: GHC 50 + Shadow Drive (the autopilot switches to standby when you take the wheel), GHC 50 only, or the Starter Pack without control unit – for boats that already have a Garmin chartplotter or GHC control.
Garmin Compact Reactor™ 40 Hydraulic Autopilot with Shadow Drive™ and GHC™ 50
The Garmin Compact Reactor™ 40 is a reliable, compact hydraulic autopilot system for smaller boats (under approx. 7–9 m) that keeps your course comfortably and safely.
Key features:
- Solid-state 9-axis AHRS (attitude/heading reference system) – accurate heading, low power consumption and flexible mounting.
- Shadow Drive™ technology – take the wheel at any time and the autopilot disengages; release it and the autopilot resumes holding the new heading.
- Strong, stable course keeping in waves and wind for smooth progress.
- Easy set-up and calibration, so you can get out on the water quickly.
- Multiple control options: control the autopilot from the GHC 50, a compatible chartplotter or other supported Garmin devices.
