Our Most Responsive Autopilot System on the Water

  • Solid-state 9-axis Attitude Heading Reference System (AHRS)
  • Minimizes heading error course deviation rudder movement and power consumption while providing a comfortable ride
  • Minimal commissioning and calibration
  • Patented Shadow Drive™ technology keeps you in control even when autopilot is engaged
  • Requires a compatible Garmin chartplotter

With a complete package designed for powerboats and sailboats 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 sailboats. 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 minimizes heading error course deviation rudder movement and power consumption while providing a comfortable ride for all on board.

Reacts to 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 BlueChart® g2 Vision® charts (sold separately) you gain optional features such as Auto Guidance2 which automatically steers GPS paths.

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 maneuver the boat. The autopilot automatically re-engages when you hold a steady course.

Amazing pillows!
Color: White, Size: Queen(Pack of 2)
These are fantastic pillows! A little background. I'm a side sleeper and toss and turn throughout the night. I've struggled with sleep issues for literally decades - insomnia, tossing and turning, waking up multiple times a night to use the bathroom, waking up way too early and not being able to get back to sleep. Every night it's a combo of those things or all of those things. I've also had some neck pain and stiffness for a couple of months. If you've ever dealt with that you know it will affect sleep which will then affect productivity and mood. It's a terrible spiraling and compounding thing to deal with, very stressful. I figured the contour pillow I had which once was actually helping was unfortunately the culprit. So I went on the hunt for another pillow. I ordered what I thought was the old Rejuvenite pillow (those were fabulous!) and got burned on a bait and switch. The pillow ended up being way too soft and gave me worse neck pain. Figuring I'd try to salvage what was a $115 pillow, I invested in a very thin pillow to put underneath. It was too high. Getting pretty frustrated, I ordered the cheaper Utopia pillows here on Amazon. Those actually were not terrible because they did take away my neck pain, but I was still tossing and turning at night and still feeling unrested in the morning. I decided I'd give it one last shot and luckily found these when they were discounted by a few bucks. They didn't have many reviews which was actually a great sign for me because it means the company lets their product speak for itself. I got these in several days and was thrilled to see upon opening the package that they were sealed and the directions do not require you to open the package and let them expand for 24 hours. You literally just take the edges and fluff 2-3 times and that's it! They are ready to go and they definitely do feel perfect after doing that. I was skeptical when I put them on my bed because they are soft and I worried they'd be too soft. I felt my head sink into the pillow a bit and then was surprised to feel at a certain point it just feels like the pillow is cradling your head with the right amount of support. I wouldn't describe it as firm, just soft but stable support. Really comfortable. But the real test was how it would perform during sleep. I'm so thrilled to report that I had an amazing night of sleep! No neck pain, no stiffness, zero tossing and turning, no insomnia, no waking up during the middle of the night, and no waking up early. I put my head down, fell asleep, and slept like a log for about 7.5 hours straight, which is literally unheard of in my world. I'm very lucky if I get 5 solid hours of sleep. I woke up and popped out of bed. My mood was great (still is later in the day) and I was not tired in the afternoon when I normally feel the fatigue kicking in. This is the first day for as long as I can remember that I do not feel that nagging tiredness behind my eyes and in my body that always seems to be a steady background actor in my life. I feel great and full of energy and I was able to tackle a bunch of tasks on my someday list. This is so promising I didn't want to wait to share. If you are on the fence and are dealing with similar issues to mine, I'd encourage you to just try these. What's also amazing is these come in a set. I'm only using one so I basically have another one to use if the first one ever fails. This is the best investment for sleep I've ever made! Update: Well, after a trial period I'm removing a star because my dreamy sleep was short lived. I started to wake up more frequently during the night with these and gave up midway through the night one night. I'm still using these for back support while I sit up or hang out in bed because they are still super comfortable that way and oddly these work well for naps. Hopefully, you have better luck than me!

Actually feels like a hotel stay
Color: White, Size: Queen(Pack of 2), Color: White, Size: Queen(Pack of 2)
I've been looking for that specific hotel feel without spending a fortune, and these Serta pillows nailed it. They are categorized as medium-firm, which I find perfect, they have that initial plush softness when you lay down, but they don't flatten out completely by morning. The 400-thread-count cotton cover feels high quality and breathable, so I haven't dealt with any overheating. I'm a side sleeper and my husband sleeps on his back, and we both find them super comfortable. If you want a pillow that balances support with that cloud like luxury these are a great pick.

Decent
Color: White, Size: Queen(Pack of 2)
They are only used as a backup pillow for my special pillows I use since I have pillows with holes in the middle for my earrings. I also use them for when I lean on my headboard to watch tv. I like them they are squishy. Kind of expensive I feel like but not terrible

I love these pillows
Color: White, Size: Queen(Pack of 2)
Very good pillows, comfortable and with that hotel style. They have medium firmness, so they work well for any sleeping position. They feel fresh, of good quality and do not crush easily. Excellent purchase.

Worth it, I have 2
Style: All Season, Size: King
Soft, good material, I like the thickness. Does not feel cheap.You do have to put it in a dryer on really low to fluff it up. Check it after 20 minutes. Pull it out fluff it up and put it back in the dryer. Do not use hot heat. I also put it in a linen duvet.
