Garmin Reactor 40 Mechanical/Retrofit/Solenoid Corepack without GHC

COREPACK COMPATIBILITY

This corepack works with direct or cable-actuated steering systems to support heading hold, wind hold, step turns and tack/jibe modes.

SOLID-STATE 9-AXIS AHRS

With its advanced solid-state 9-axis AHRS, you can mount Reactor 40 nearly anywhere, in any orientation. It even reduces power consumption, minimizes heading error and more.

REACTS TO WATER CONDITIONS

Hold your course on the sea — this autopilot reacts to conditions, so you can remain confident even when you’re pitching or rolling.

SIMPLE CALIBRATION

All autopilots require commissioning and calibration. Reactor 40 makes it quick and easy.

SHADOW DRIVE™ TECHNOLOGY

Gain more freedom when maneuvering your boat. On hydraulic installations, this corepack allows for optional Shadow Drive technology to automatically disengage the autopilot when you turn the wheel.

THREE CLASS DRIVES

Choose between class A, class B compact or class B drive units for your steering system (sold separately). All Garmin linear drives include built-in rudder feedback sensing.

WIRELESS REMOTE CAPABILITIES

Control your autopilot from anywhere on your boat by using your compatible Garmin devices, including the Reactor autopilot remote, select quatix® marine smartwatches and more (requires a compatible Garmin chartplotter or GHC 50 autopilot instrument).

OPTIONAL GHC 50 BUNDLE

Combine the Reactor 40 corepack with the GHC 50 autopilot instrument to add a dedicated, touchscreen autopilot display to your helm. Plus, GHC 50 allows you to share data and settings with Garmin MFDs and other installed Garmin devices.

OPTIONAL GRF™ 10 SENSOR

For even more peace of mind, add the GRF 10 rudder feedback sensor to further enhance your autopilot’s performance (requires GHC 50 autopilot instrument or compatible Garmin chartplotter).

POWERBOAT AND SAILING FEATURES

When connected to your compatible Garmin chartplotter, all Reactor 40 corepacks offer powerboat and sailing features, including heading hold and step turns — plus wind hold and tack/jibe when paired with a wind sensor (sold separately). You can even gain additional benefits such as the follow route and Auto Guidance+™ features¹.
