Ideal Entry-level Autopilot System

  • Includes Compact Reactor 40 CCU ECU pump and other autopilot components needed to add to your compatible chartplotter
  • Recommended only for single-engine outboard boats less than 30 foot long1
  • Solid-state 9-axis Attitude Heading Reference System (AHRS)
  • Minimises heading error course deviation rudder movement and power consumption while providing a comfortable ride
  • Minimal commissioning and calibration

Designed for boats less than 30-foot-long the Compact Reactor 40 hydraulic autopilot provides relief from manually holding the wheel to maintain course especially when cruising at moderate to high speeds. Sit back at the helm and enjoy your time on the water as the solid-state 9-axis AHRS technology delivers a comfortable ride.

Offered in 3 different corepacks this autopilot lets you configure your autopilot setup depending on the features you need and how much you want to spend. Buy the starter pack (compatible chartplotter required) add a GHC 20 marine autopilot control unit or add both GHC 20 and the Shadow Drive attachment.

The autopilot is easy to install with flexible mounting options and quick easy commissioning. Choose a corepack with our patented Shadow Drive technology and simply turn the wheel to take control of the helm; hold a constant course to re-engage. It integrates with compatible Garmin electronics to control the autopilot from the chartplotter display. And it can be engaged to follow an Auto Guidance path (requires BlueChart g3 charts).

Solid-state 9-axis AHRS
With its advanced solid-state 9-axis AHRS Compact Reactor 40 provides you with more flexible mounting options. 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 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 Electronics
Combined with our compatible networked electronics you can have full control of Compact 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 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 Compact Reactor 40 autopilot supports optional 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
Compact Reactor 40 can be operated directly from your compatible Garmin chartplotter screen or by 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 radar and chartplotter. An optional handheld wireless remote control is also available.

Okay for the price!!! Good Quality!!
Color: Green
{Dveracious Shopper:- Just so you know, My reviews won't have fancy videos and photos sometimes but I post honest reviews based on the usability of these products and I did pay my own money to buy these products, so its not a free product review. I use it before I review it as I am committed to provide honest feedback based on the product's usability} My daughter chose and she is using it on her I pad. I love the functionality of it However not a fan of the removable keyboard, even though some may like it. it protects the I pad and that's what we won't. Has pretty color options too. Fits great.

Good for the price
Color: Black
I used to have a Smart Keyboard. If you compare it to that (discontinued) or the Magic Keyboard, you’ll be unhappy. But I can’t imagine a better product at this price point. The good: • Case is substantial & protective. • When in use, the iPad stays upright (it rests in 1 of 2 grooves, so angle is mildly adjustable). • Keyboard is easy to install, & connects quickly when you turn it on (maybe 2 seconds) • Keys feel good when typing • Lights are fun (but you can turn them off, if you’re not into that). • It works great for casual use, & it’s so cheap (I paid $28). In comparison, the Magic Keyboard is $250. If you do a lot of typing though, you want to invest in getting something better. The meh: • The case is a bit fiddly to open & get set up, mainly bc the keyboard sits in the center flap when closed, but you have to move it down to the end in order to use it. • I type about 45 wpm, & it keeps up. There are occasional lags though. If you type fast, I think you’d be frustrated, when you have to stop & retype what it missed. • It turns off after a couple minutes, to save battery. Which is mildly annoying when I resume typing, & have to retype my sentence bc it needed to wake up. It only takes like 2 seconds, not a huge deal. But bc of this, I def wouldn’t recommend using during lectures or meetings where you have to keep up. For my casual use (maybe a couple hours per week), it works great. • You have to remember to turn it on & off, to conserve battery. You have to remember to charge it, & to do that you may need 2 charging cords for your iPad. The Magic Keyboard, in comparison, is powered by your iPad. You don’t even need to think about it.

Good purchase ! I recommend this one
Color: Purple
⭐️⭐️⭐️⭐️⭐️ Stylish, Functional, and Surprisingly Durable — A Great iPad Companion I’ve been using this purple case with a built-in keyboard for my 9th generation iPad, and I’m genuinely impressed with its overall quality. It hits the mark in several key areas: 🔹 Design & Aesthetics: The color is I purchased was a light purple—elegant without being overly flashy. It adds a pop of personality to my setup, which I appreciate. The stitching and build look well-finished, giving it a premium feel. 🔹 Keyboard Functionality: The attached keyboard connects easy and holds a strong charge. The keys are surprisingly responsive for a compact layout, and the typing experience is smooth and tactile—not mushy like some others I’ve tried. Great for emails, journaling, or casual work on the go. 🔹 Protection & Durability: The case feels sturdy without being bulky. It offers solid protection, especially around the corners, and the iPad feels secure when clipped in. After tossing it into bags and using it daily, it still looks and feels great—no odd flex or signs of wearing down fast 🔹 Touch & Comfort: The material has a soft-touch finish that feels great in the hand. It’s not slippery, and it doesn’t attract fingerprints easily. It also makes it comfortable to use the iPad in different positions—typing, drawing, or watching shows. 🔹 Extras & Usability: I like that the case doubles as a stand and supports multiple angles. The magnetic closure is a nice touch, keeping everything secure when closed. Overall, this case+keyboard combo offers a lot of value. It’s functional, stylish, and reliable—exactly what I was hoping for. If you’re looking for a practical upgrade that doesn’t sacrifice style or quality, I’d say this one’s worth a look.

Pretty Color & Lighting
Color: Pink
I found myself needing a keyboard case for my iPad pro (10.5 inch). I stumbled across this one with great reviews. Once I opened the box it arrived in, it lived up to its reviews. The case feels smooth and appears to have great quality. The keys on the keyboard sound like a typewriter which I love. I was unaware that the keyboard lit up but to my surprise the lighting was extremely bright even in the daylight. The weight of the both the keyboard, iPad, and case all together feels as heavy as a FiveStar notebook. Connecting the keyboard to the iPad was the easiest part because once you pop your iPad in the case and turn on the keyboard and press the connect button you head to the bluetooth settings of your iPad to pair them. Performance wise sometimes the keyboard snoozes after a few minutes of not being used and takes a second to start typing again. Besides that it works great when you’re constantly typing. Overall I love the color of the case and it’s definitely a money spent well.
