Garmin Reactor 40 Autopilot With SmartPump v2 And GHC20 is a hydraulic corepack that delivers precise, responsive steering for powerboats and sailboats. Its solid-state 9-axis AHRS lets you mount the system in virtually any orientation, while advanced control reduces heading error, course deviation, and unnecessary rudder movement for a smoother ride and lower power draw. Commissioning and calibration are fast and straightforward, so you can enjoy hands-free navigation sooner.
