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.

Switched from luxury brands and never looked back!
Size: 19 Ounce (Pack of 1)
I used to spend way too much on high end body moisturizers thinking the price meant better results. Tried CeraVe on a whim and realized I was paying for packaging and fragrance this whole time. This does more for my skin than anything I used before. I use it daily all over my body after showering and my skin stays soft the entire day. No irritation ever. The formula is so gentle that I forget I'm even wearing anything. No fragrance, no stinging, no breakouts. Just clean hydration. If you have sensitive skin and you're nervous about trying something new, this is about as safe as it gets. The 19 oz tub lasts a long time even with daily full body use. Ceramides and hyaluronic acid at this price point is honestly ridiculous value. Save your money on the luxury stuff and just get this.

So Far, Really Good for Dry and Sensitive Skin
Size: 8 Ounce, Size: 8 Ounce
I’ve only been using this moisturizer for about 2 weeks, but so far I really like it. It keeps my skin feeling hydrated throughout the day without feeling greasy or heavy. The texture is smooth, absorbs nicely, and doesn’t irritate my skin at all. I also noticed my skin feels softer and less dry since I started using it. It’s simple, gentle, and works well for everyday use, especially if you have sensitive skin. So far I haven’t experienced any breakouts or strong fragrance issues, which I appreciate. Too early to say long-term results, but my first impression has been very positive and I would buy it again.

Gentle but effective
Size: 4 Fl Oz
I’ve used quite a few exfoliating products over the years, but I keep coming back to this one because blackheads seem determined to make themselves at home in my pores. No matter how consistent I am with the rest of my skincare routine, they always find a way to show up, especially around my nose and chin. What I like most about this exfoliant is that it works without feeling harsh. It has a lightweight liquid texture that applies easily and absorbs quickly. Unlike physical scrubs that can leave my skin feeling irritated or over-exfoliated, this provides gentle chemical exfoliation with none of the rough scrubbing. My skin feels smoother after use, and I don’t get the tight, stripped feeling that some acne-focused products can cause. After using it regularly, I notice fewer clogged pores and a visible reduction in blackheads. My pores also look less noticeable, and my skin texture appears more even overall. It helps keep congestion under control before it turns into larger blemishes, which is a big reason why it has remained a staple in my routine. For me, this is one of those rare products that manages to be both effective and gentle at the same time. If blackheads and clogged pores are an ongoing battle, this has been one of the most reliable products I’ve found for keeping them under control while still being comfortable enough for regular use. Summary: This exfoliant has earned a permanent spot in my skincare routine. It helps reduce blackheads, keeps my pores looking clearer, and improves overall skin texture without irritating my skin. For anyone dealing with persistent pore congestion, it’s easy to see why this product has such a loyal following.

If you actually understand how to use it, it's amazing.
Size: 4 Fl Oz
My skin type: - Very Dry, easily dehydrated - Oily nose - Prone to stubborn acne and closed comedones - Redness on chin and cheeks (not rosacea) I already use a nightly Tretinoin cream (.04% concentration) to help with my acne and premature signs of aging but decided with my derm that incorporating a BHA would be a good idea to help with my seriously stubborn closed comedones and some irritating textural issues. It was between this and the Cerave SA lotion and I ultimately decided on this due to the higher concentration of salicylic acid. It's moisturizing, and feels sticky for the first 5-10 minutes after application but seems to sinks in to something of a satin finish on me and I can no longer feel it on my skin. You just have to be a little patient. My skin feels well hydrated and plump after it settles and looks really smooth and my pores aren't as obvious. It sits just fine under makeup for me but I'm not a new user to chemical exfoliants so I don't have lots of dead skin pilling up or sloughing off when I use it, my skin is, for the most part, already very smooth outside the acne and CCs. Occasionally I'll apply it further down my neck/decolletage than usual and WOW do I old skin just ball up and peel right away - it's so gross but also satisfying. So those that don't exfoliate often or are new to BHA/AHAs will likely have issues with foundation until their skin adjusts (but it will adjust). My advice in those cases is to either use this at night for the first few weeks or just accept going barefaced for a little while if you can. I'd strongly suggest not applying this product over anything that you feel does not dry down fully, the times I've attempted to use it after serums or heavier products it takes forever to sink in and sometimes never fully does. I save all my serums and essences for after this has absorbed and it's far easier to work with it as a result. My steps go like this most days: ACWell Licorice toner --- PC 2% BHA --- 10% Niacinamide serum --- TO Matryxil serum --- Secret Key Black Snail cream or Syn-ake cream w/ 3 drops Stratia Fortify oil --- Sunscreen. It works fairly quickly IMO, on my neck where I typically don't apply my Tret at night I noticed the peeling and balling of dead skin on day one and on my face where I have a patch of really awful CCs I noticed them getting smaller and smoother by around day 3-4. I'm going on about 8 days now and they're barely visible unless I'm right up in the mirror and feel as if they're almost gone when I touch my fingers to that area. I do have some slight peeling of the skin around my mouth and nose but it's not terrible (likely because I already exfoliate the heck out of my skin with the tret). Some tips and things keep in mind: 1) DO NOT RINSE IT OFF. I don't understand some of the top reviews advising people to do that, it says on the bottle not to rinse and nearly all chemical exfoliators are meant to be left on until the next cleansing specifically so they can do their job. If you rinse it off you're either going to prevent it from properly exfoliating or end up irritating the hell out of your skin. If you have oily skin and feel this might be heavy on you than you can probably just use this on bare skin and then sunscreen if you use in the AM or a lightweight lotion/cream and be done with it, but you need to leave it on your skin. 2) You have got to use sunscreen while you're using this product! Any BHA or AHA exfoliant causes increased sun sensitivity and you have to address that in your routine. You should already use sunscreen daily but it becomes a must when you incorporate a chemical exfoliator or you risk sun damage. 3) Less is more! Don't slop this on your face or soak a cotton pad in it, a little goes a long way and you'll be kicking yourself if you apply way too much and have to wait 20+ minutes for it to sink in. Use a shake or two and add more if needed but go easy. 4) Expect some irritation initially. Chemical exfoliants can be harsh and rough even on sturdy skin and you have to give yourself time to adjust. Over-exfoliation is a possibility but sometimes just introducing a BHA or AHA into your routine can cause some sensitivity. Don't panic and just be gentle to your skin. Use ceramides (like Cerave Skin Renewing cream) or fatty oils to soothe your face if needed and try to stay away from any harsh products or acids like Vitamin C right after applying this to avoid really burning your face.
