Garmin Compact Reactor 40 Hydraulic Autopilot with GHC 50 Instrument Pack

Garmin Compact Reactor 40 Hydraulic Autopilot with GHC 50 Instrument Pack

Garmin Compact Reactor 40 Hydraulic Autopilot with GHC 50 Instrument Pack are the perfect solution for single-engine outboard vessels. Whether you are navigating a busy estuary or cruising along the coast, this system provides the relief you need from manually holding the wheel, allowing you to focus on the journey, your fishing lines, or simply enjoying the view.

This comprehensive pack includes the GHC 50 Autopilot Instrument, featuring a bright, edge-to-edge glass touchscreen that integrates seamlessly with your helm. With its advanced 9-axis AHRS (Attitude Heading Reference System), the Reactor 40 reacts to the sea conditions to keep you on course—even when the boat is pitching and rolling in choppy British waters.

Why Choose the Compact Reactor 40?

• • Tailored for Smaller Boats: Specifically engineered for hydraulically steered powerboats under 25 feet in length.
  • Intuitive Control: The GHC 50’s high-resolution 5-inch display makes navigation a breeze with its premium interface and easy-to-use touch controls.
  • Simple Setup: We know you’d rather be on the water than at the dock; that’s why Garmin has made commissioning and calibration remarkably quick and straightforward.
  • Unrivalled Stability: The solid-state 9-axis AHRS allows the sensor to be mounted almost anywhere on the boat and in any orientation, while significantly reducing power consumption and heading errors

Garmin Compact Reactor 40 Hydraulic Autopilot with GHC 50 Instrument Pack FAQs

Is the Compact Reactor 40 suitable for my boat?

This specific "Compact" model is designed primarily for single-engine outboard boats under 25 feet (approx. 7.6 metres) in length. It is an entry-level, cost-effective solution for boats with hydraulic steering. If your boat is larger, has twin engines, or a high-performance hull, please speak to our workshop team, as you may require the standard Reactor 40 with a larger pump.

What makes the GHC 50 instrument different from previous models?

The GHC 50 is Garmin’s latest premium 5-inch touchscreen display. It features a bright, edge-to-edge glass WVGA display that is incredibly easy to read, even in direct sunlight. It doesn’t just look the part—it’s designed to match the sleek aesthetic of the modern GPSMAP x3 and 8600 series chartplotters.

Does this pack include the hydraulic pump?

Yes, this specific pack (010-02794-07) includes the 1.0-litre pump, the Reactor 40 CCU (Course Computer Unit), the GHC 50 display, and the ECU (Electronic Control Unit). It is a comprehensive corepack for a standard hydraulic installation.

What is Shadow Drive™ technology, and do I need it?

Shadow Drive is a fantastic safety feature that automatically disengages the autopilot the moment you turn the helm manually. This allows you to make quick manoeuvres without having to press any buttons to take control.

Note: Some packs include the Shadow Drive sensor as standard, while for others it is an optional add-on. We highly recommend it for busy UK coastal waters.

Can I control the autopilot from my Garmin smartwatch?

Absolutely. Because the system features ANT+ connectivity, you can pair it with compatible Garmin devices like the quatix® marine smartwatch or the Garmin Autopilot Remote. This gives you the freedom to adjust your heading or engage patterns from anywhere on the boat—perfect for when you're busy on deck.

How difficult is the calibration process?

One of the best things about the Reactor 40 series is the 9-axis AHRS (Attitude Heading Reference System). This advanced technology means the unit can be mounted almost anywhere in any orientation. The commissioning and calibration process is remarkably quick and user-friendly compared to older systems, getting you out of the marina and onto the water faster.

Will this work with my existing Garmin Chartplotter?

Yes, it integrates seamlessly. Via the NMEA 2000 network, you can share data and settings across your Garmin MFDs. If you have a compatible chartplotter, you can even gain advanced features like "Auto Guidance+" to follow a path that avoids known hazards and shallow water.

Do I need professional installation?

While the Compact Reactor 40 is designed for "simple" installation, hydraulic systems require "bleeding" and precise plumbing. As an authorised Garmin dealer with a full-service boatyard in Brightlingsea, our engineers can handle the entire fit-out for you, ensuring your warranty is protected and the system is perfectly tuned for your hull.

Can it handle rough North Sea conditions?

Yes. The 9-axis AHRS is specifically designed to react to sea conditions. Even when your boat is pitching and rolling in a swell, the autopilot works to keep you on a steady course, reducing the "snaking" often found in lesser systems and saving you fuel in the process.
