The Garmin Reactor 40 Mechanical Retrofit Corepack with GHC 50 is an autopilot system built to retrofit boats that use mechanical steering. It suits both powerboat and sailboat setups and pairs the Reactor 40 core components with the GHC 50 control head.

• Compatible with a range of steering systems, broadening the types of boats it can be fitted to
• Heading hold — keeps the boat tracking a set compass heading without constant manual correction
• Wind hold — steers relative to the wind angle for sailing
• Step turns for adjusting course in measured increments
• Tack and jibe modes to assist sailors through those maneuvers
• GHC 50 control head for operating and monitoring the autopilot

Offered by Mirage Fish Finder, this corepack brings autopilot control to mechanically steered powerboats and sailboats with support for heading and wind-based steering modes.
