Go beyond the limits of recreational diving with SCUBAPRO's S-Tek technical diving gear system, which re-invents the classic back plate and wing system (BPW) with a clever design focused on adjustability, reliability, and comfort. Built tough and loaded with features, this S-Tek Pro System includes a 3D-formed stainless steel backplate with harness and a donut wing with 30/40/60-pound lift.
Offering a revolutionary design that will make your time at depth more comfortable and enjoyable, the back plate features adjustable TEK LOC shoulders to ensure a snug fit while the donut wing delivers reliable buoyancy control regardless of diving position thanks to its rounded profile.
Comfortable and Convenient Back Plate
The 3D-formed back plate features a softened organic shape, curved central profile, and fully radiused edges for greater comfort.
The S-Tek Pro Harness includes recessed Wing-Nut Sockets that are compatible with standard 8mm and 10mm Wing Nuts or the included S-Tek Ergo Nuts, which are designed to be used with cold, wet, or gloved hands.
Durable Donut Wing
Delivering industry-leading abrasion resistance that's great for cave diving, the S-Tek Donut Wing's outer shell is made from durable, performance-oriented 1000D Cordura fabric, while the inner bladder is made from 500D Cordura.
Additionally, the wing's rounded profile reduces air trapping, helping ensure smooth, controlled air migration.
Smooth, Balanced Tek BPI
The S-Tek Donut Wing includes the Tek BPI (Balanced Power Inflator) with a K-style layout, providing an extremely robust, lightweight design for smooth, balanced air control during inflation and deflation.
It features an easy-to-control balanced inflation button, a rotating soft mouthpiece for comfortable oral inflation, and an ergonomic design.
