Product Information
The SCUBAPRO X-TEK Donut Wing Double Tank Configuration, 40 lb / 18 kg Lift, is a technical back-inflate BCD wing built for doubles diving, with a rugged 1680D Ballistic nylon outer shell, a 420D nylon inner bladder and a SCUBAPRO Balanced Power Inflator (BPI).

This wing is built for technical and back plate divers who want dependable control and stability at depth in any diving position, whether swimming horizontal, working a line, or hovering to deploy a stage.

Frequently Asked Questions
How should a scuba BCD fit?
A BCD should fit snugly enough that it does not ride up toward your ears when inflated, while still letting you breathe fully. Fasten the waist and cummerbund first, then adjust the shoulder straps so the tank sits close to your back and the shoulders cannot slide off. With the BCD fully inflated at the surface you should still be able to take a deep, comfortable breath; if it squeezes your chest, loosen it or move up a size.
How do I rinse and care for a BCD after diving?
Rinse the outside in fresh water and also flush the inside of the bladder, because salt water gets in through the inflator and dump valves. Fill the bladder roughly a third full of fresh water through the oral inflator, slosh it around, then drain it out through the inflator and each dump valve. Hang it to dry out of direct sunlight and store it partially inflated so the bladder walls do not stick together.
Should I use integrated weights or a weight belt?
Integrated weight pockets carry the lead in the BCD itself, which many divers find more comfortable and easier on the hips, while a weight belt keeps the weight independent of your BCD. Either way, you must be able to release your ditchable weight quickly with one hand, and your buddy should know how your system releases. Non-ditchable trim pockets are useful for balance but should never hold weight you might need to drop.
How do I pack a BCD for travel?
Make sure the BCD is completely dry inside and out before packing so it does not mildew in transit. Remove all weights, deflate it fully, and fold or roll it around softer items such as a wetsuit to cushion the inflator and valves. Avoid hard creases in the air cell, and unpack and air it out as soon as you arrive.
When does a BCD need to be serviced?
Follow the service interval in the manufacturer's manual, which is commonly an annual inspection alongside the rest of your life-support gear. Have the inflator, dump valves, and bladder checked any time the inflator sticks, free-flows, feels rough, or the BCD holds air poorly. Between services, confirm that it inflates and deflates properly as part of every pre-dive check.
What is the difference between a jacket-style and a back-inflate BCD?
A jacket-style BCD holds air in panels that wrap around your sides as well as your back, while a back-inflate BCD keeps the entire air cell behind you. Jacket styles tend to feel very stable and upright at the surface, and back-inflate styles keep the chest clear and are often preferred for horizontal trim underwater. Neither is objectively better, so treat it as a fit and preference decision and try both if you can.
Will my BCD fit any scuba tank?
Most recreational BCDs use an adjustable cam band sized for common single-cylinder diameters, so standard aluminum and steel tanks generally work. Re-check the band tension after the first wetting, because webbing can relax slightly and let the tank shift. If you dive doubles or unusual cylinder diameters, confirm compatibility with the manufacturer before assuming it will hold.
Can the SCUBAPRO X-TEK Donut Wing be used with a single tank instead of doubles?
This listing is the double tank configuration of the X-TEK Donut Wing. Contact us to confirm single-tank use before ordering.
Does the X-TEK Donut Wing have integrated weight pockets?
No. The Weight Integrated spec is listed as N/A, so this wing has no built-in weight pockets and pairs with a separate harness and back plate.
Is 40 lb / 18 kg enough lift for doubles diving?
This specific wing is rated at 40 lb (18 kg) of lift, which is the capacity published for this listing. The X-TEK Donut Wing line has been offered in more than one lift capacity, so confirm your gas and gear load against this 40 lb rating, or call us to talk through your doubles configuration.
