Experience confident, hands‑free steering with the Garmin Reactor 40 Corepack With GHC 50. This hydraulic autopilot is designed for powerboats and sailboats, delivering precise course keeping even as the sea throws a heading off course. Its solid‑state 9‑axis AHRS lets you mount Reactor 40 almost anywhere, in any orientation, while reducing power consumption and minimizing heading error for smoother, more efficient navigation.
Designed for real-world versatility, Reactor 40 responds to wave action and sea conditions so you stay on your intended track. Calibration is fast and easy, getting you on the water and steering with minimal setup. Control the autopilot from anywhere on the boat using a compatible Garmin chartplotter or the GHC 50 autopilot instrument, giving you freedom and convenience when maneuvering.
