Description
Description
The SCUBAPRO S-TEK Pure Back Plate / Wing System provides a streamlined, DIR-aligned setup for technical divers who prefer twin-tank diving on scuba and underwater missions. This complete kit blends a Pure Harness with Back Plate and a Donut Wing (40 lb or 60 lb lift) to maintain stable buoyancy and precise trim in demanding dive conditions.
Key construction details focus on durability and predictable performance. The outer shell uses PU-coated 1000 Denier Cordura Nylon, paired with a 500 Denier Cordura inner bladder, while the back plate is stainless steel. The Donut Wing features a rounded profile designed to minimize air trapping, enhancing control during dives.
The harness and hardware are designed for easy handling in the field. The continuous webbing harness offers fixed-shoulder length or Extender mode for easier donning and doffing. Ergonomic features include EVO Angle webbing slots to reduce abrasion, a recessed Wing Nut Socket with S-Tek Ergo Nuts for gloves and wet conditions, and built-in carry handles. The system also includes dedicated mounting points for trim weights and argon tanks, a silicone epaulet on the left shoulder, and guide bands to keep the inflator hose in place. Additional attachment points provide versatile configuration for a complete diving gear setup.

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.
