Our Most Responsive Autopilot System on the Water

  • Minimal commissioning and calibration
  • Patented Shadow Drive technology keeps you in control even when autopilot is engaged

With a complete package designed for powerboats and sailing boats Garmin brings an advanced marine technology to the boating public that was once only available for commercial boats. The Reactor 40 autopilot series is simply the most responsive autopilot system we have ever offered.

Reactor 40 autopilots are very versatile. Both powerboat and sailing features are available in all corepacks including heading hold wind hold tack/jibe step turns and more; simply pick the autopilot that's compatible with your existing steering system.

The Reactor 40 hydraulic autopilot corepack is ideal for all types of hydraulically steered powerboats inboards outboards stern drives and diesels or hydraulically steered sailing boats. This robust unit gives powerboat users an easy-to-use autopilot system to rely upon for navigation. With its solid-state 9-axis AHRS Reactor 40 mounts nearly anywhere in any orientation and requires minimal commissioning. Our patented Shadow Drive technology gives boaters the security of knowing they maintain control even when relying upon the autopilot.

Solid-state 9-axis AHRS
With its advanced solid-state 9-axis AHRS you can mount Reactor 40 nearly anywhere in any orientation. In addition this new system greatly minimises heading error course deviation rudder movement and power consumption while providing a comfortable ride for all on board.

Reacts to Sea Conditions
This amazing autopilot actually reacts to the sea to hold your course. Even when the boat is pitching and rolling you can remain confident that the Reactor 40 autopilot will keep you on your desired course.

Minimal Commissioning and Calibration
All autopilots require commissioning and calibration all of them. We know you just want to get on the water so we made this process as fast and easy as possible. That's the power of simple.

Full Integration with Garmin Chartplotters
Combined with a compatible Garmin networked chartplotter you can have full control of Reactor 40 from wherever you are on the boat. In addition to holding its course in virtually all weather and wind conditions the system can smoothly perform a variety of preprogrammed trolling and search procedures. Plus with a compatible Garmin networked chartplotter and optional BlueChart g3 Vision charts (sold separately) you gain industry-leading coverage clarity and detail with updated coastal charts that feature integrated Garmin and Navionics content.

Stay in Control with Shadow Drive Technology
The Reactor 40 autopilot features patented Shadow Drive technology. This gives you the security of knowing you maintain control even when the autopilot is engaged. The Shadow Drive system automatically disengages the autopilot if the helm is turned giving you the freedom to manoeuvre the boat. The autopilot automatically re-engages when you hold a steady course.

Connect to Networked Devices
The Reactor 40 autopilot is operated using up to 3 GHC helm control units. GHC communicates with the autopilot system via your NMEA 2000 network so autopilot heading data can be shared easily with other devices. This enables MARPA and chart overlay when connected to a Garmin chartplotter. An optional handheld wireless remote control is also available; however for the highest level of convenience control your Reactor autopilot using a compatible quatix or quatix 5 marine multisport smartwatch.

Charming Coloring Book — Fun for All Ages
Format: Paperback
This coloring book has quickly become a favorite in our house! The illustrations are adorable and relaxing, making it just as enjoyable for adults as it is for kids. My daughter and I have spent hours coloring together, and it’s been a great way to unwind after school or on quiet weekend afternoons. What I love most is how versatile it feels — the designs range from simple and playful to more detailed, so everyone finds pages that match their mood and skill level. It’s also a fun way to keep little hands engaged without screens. Whether you’re looking for a creative activity to share with your kids or a gentle, artistic escape for yourself, this coloring book delivers plenty of charm and enjoyment. The only reason giving 4 stars is because of the price. Although the book is great, I do not think it is worth almost $10.

Excellent Price & Function!
Size: No Size, Style: 4V Screwdriver_Twist 2.0 2pc Set
An excellent power screwdriver for assembly work where high torque is not needed. I haven't stripped any screw threads yet. The battery lockout feature is nice especially if it's bumping around in a tool box. It feels good and the switch works good too. The battery indicator LEDs work good too. The adjustable angle on the end works good too. Watching it turn through the clear windows is a neat function too. It works better than the Ryobi screwdriver it replaced. The torque is good without having too much torque for lighter work. It looks nice and feels of really good quality. The battery life appears to be good as well. I would buy it again when needed. Excellent price!
