Garmin Reactor 40 Mechanical Retrofit Corepack with GHC50

The Garmin Reactor 40 Mechanical Retrofit Corepack with GHC50 redefines autopilot performance for powerboats and sailboats alike. Engineered to work with a wide variety of steering systems, this solid-state, 9-axis AHRS corepack lets you mount the unit nearly anywhere—even in challenging sea conditions—while delivering precise course control and energy efficiency. Calibration is fast and easy, so you can get on the water and stay on course with minimal setup.

Overview

• Advanced navigation intelligence: Solid-state 9-axis AHRS provides reliable attitude data, enabling accurate autopilot responses in pitching or rolling seas.
• Broad steering compatibility: Works with direct or cable-actuated steering systems and supports class A, class B compact, or class B drives (drives sold separately). All Garmin linear drives include built-in rudder feedback sensing.
• Powerful autopilot features: Heading hold, wind hold, step turns, and tack/jibe modes keep you on your intended route with minimal input.
• Efficient and flexible: Mount Reactor 40 nearly anywhere, in any orientation, with reduced power consumption and minimized heading error.
• Shadow Drive ready (hydraulic installations): Optional Shadow Drive automatically disengages the autopilot when you turn the wheel, giving you full manual control when you want it.
• Remote and onboard control: Control your autopilot from anywhere on the boat using Garmin devices, including the Reactor autopilot remote and select quatix marine smartwatches (requires compatible chartplotter or GHC 50 instrument).

GHC50 Autopilot Instrument

Pair the Reactor 40 with the GHC50 autopilot instrument to add a dedicated, touchscreen helm display. The GHC50 enhances your autopilot experience by sharing data and settings with Garmin MFDs and other installed Garmin devices, making helm management intuitive and centralized.

Integrations and Control

• Wind and route features: When paired with a wind sensor (sold separately), enjoy wind hold and tack/jibe modes, plus follow route and Auto Guidance+ features for planning assistance.
• Auto Guidance+: Planning-oriented routing assistance (note: Auto Guidance is for planning and does not replace safe navigation operations).
• Shared data ecosystem: GHC50 enables data and settings sharing with Garmin chartplotters, MFDs, and other compatible devices for a cohesive navigation experience.
• Rudder feedback options: For enhanced performance, add the GRF 10 rudder feedback sensor (requires GHC50 or compatible chartplotter).

Performance and Reliability

With its robust 9-axis attitude sensing, Reactor 40 keeps your course even when the seas are rough. The system is designed for quick commissioning and calibration, minimizing downtime and maximizing time on the water.
