Garmin Compact Reactor 40 With GHC 50 And Shadow Drive Product Description
Discover Effortless Steering with Advanced Hydraulic Autopilot Technology
Imagine gliding across open waters without constantly gripping the wheel, letting the boat hold its course through choppy waves or gentle swells. The Compact Reactor 40 hydraulic autopilot pack transforms this vision into reality for smaller vessels. Tailored for single-engine outboards under 25 feet, it delivers precise control at cruising speeds, freeing you to enjoy the journey, scan for fish, or simply relax with family.
Unlike traditional systems that demand perfect alignment and rigid setups, this pack leverages cutting-edge solid-state 9-axis AHRS technology. This means flexible installation almost anywhere on your boat—upright, tilted, or even inverted—while sipping less power and sharpening heading accuracy for smoother rides.
Standout Features That Set It Apart
- Reactive Sea Keeping: Automatically adjusts to pitching and rolling motions, maintaining your selected course even in unpredictable conditions.
- Shadow Drive Integration: Senses wheel turns and instantly disengages the autopilot, giving you intuitive manual override for docking or sudden maneuvers.
- Seamless Garmin Ecosystem Control: Pair with compatible chartplotters, the GHC 50 helm display, or even select marine smartwatches for helm-anywhere operation.
- Quick-Start Calibration: Skip the hassle of lengthy setup routines—commissioning is streamlined so you're on the water faster.
- Powerboat and Sailing Versatility: Supports heading hold, step turns, and with added sensors, wind hold plus tack/jibe for sailboats.
Engineered for hydraulic steering systems, it's ideal for moderate to high-speed cruising but steers clear of low-speed trolling or extreme rough-water demands—perfect for day trips and coastal adventures.
Easy Integration for Real-World Boating
Installation shines with its compact design and versatile mounting. The core computer unit fits snugly in tight spaces, and the included 1.0L pump mounts efficiently near the steering cylinder for optimal performance. Connect via NMEA 2000 for plug-and-play networking with your existing Garmin gear.
Once linked to a compatible chartplotter, unlock advanced capabilities like route following and automated guidance paths. The GHC 50 display provides a clear, intuitive interface right at the helm, showing heading, status, and controls at a glance. Shadow Drive adds that extra layer of safety, ensuring you're always in command.
Boaters rave about how it handles beam seas better than manual steering, reducing fatigue on long runs.
