In designing the new Alpha Trim Devices, we set out to create one trim device that can do it all for back-mounted tank/s. Alpha works in warm or cold water diving enviroments and fits all hard, soft or travel backplates, Alpha is truly the only single or double tank back-mounted trim device that you will ever need. To accomplish this we drew on everything we had learned designing the groundbreaking Z and Z+ side-mount systems as well as the Delta trim devices. What emerged was a versatile trim device that will accommodate almost any type of back-mount single tank , double tank , technical, trimix, rebreather, cave, or wreck diving that you do. The key to it all was a very low profile, streamlined trim device that contours to the body. The Alpha Single, with upto 37lbs/17kgs of lift, or Alpha Doubles, with upto 60lbs / 28kgs of lift, has a much lower profile than traditional wings. This streamlining produced a trim device that simply will not “taco” or wrap up and around the side of a tank, producing drag. Neither will the Alpha Trim Device allow gas to roll around the bladder (referred to as “air shifting”) which produces instability in the divers trim. In designing the Z and Z+ side-mount systems we learned quite a bit about how the positioning of lift effects a divers trim. In previous wing designs, the emphasis was on placing the majority of the lift near the shoulders to achieve proper horizontal trim. The Alpha Trim Device puts the majority of the lift lower on the body, exactly where the diver needs it. This naturally places the diver in a flat, feet up position. Introducing the Alpha Back-mount Diving Trim Device. One trim device for all back-mount tank/s diving enviroments. Features and Benefits

The Alpha Single Tank Trim Device - Now Shipping
Secondly, we wanted to create the majority of lift where the diver actually needs it to keep their feet up and their body in that flat, horizontal trim we call the prone position. This was paramount when we designed the Z-Trim Devices. Thirdly, we wanted to have an aircell big enough to create enough lift for cold water divers and yet be streamlined enough for warm water divers. In other words, you only need to purchase one size wing for all your single tank diving. The Alpha Single Tank Trim device has 0lbs/0kgs up to 38lbs/17kgs of lift. Keep in mind when the Alpha Trim Device is empty it will NOT "Flap" around or taco around the tank. It remains snug and streamlined around your body, reducing drag and creating easy movement through the water. Fourth, we wanted to ensure that the inflate and deflate ability of the device functioned excellently while in the horizontal position. We spend the majority of our diving time underwater in the flat and horizontal prone position so the deflate mechanism should be positioned to accommodate that and not force the diver to go feet down or vertical to deflate using the LP hose. In the Alpha series we decided to mount the LP inflate and deflate in the traditional manner, with the OPV on the left rear of the wing and LP inflator/Deflater mount to the top of the wing.

The Alpha Double Tank Trim Device - Now Shipping
Designing the new Alpha Trim Devices we ported over all the technology and knowledge we learned when designing the Z-System Side Mount System. We first had to ensure that we created a very low profile and streamlined "buoyancy wing" that would contour to your body - much like the Z-Trim side mount trim devices do. This would reduce drag and reduce the amount of air "shift" from side to side in the wing or trim device, which ultimately causes instability.
