Scubapro S-Tek Pro System, Stainless Steel Backplate, Donut Wing 40 lb/18kg

A technical backplate-and-wing harness system with a stainless steel backplate and a 40 lb donut wing, built for single-tank technical configurations.

Wing / backplate

Modular harness and wing, the standard technical-diving setup. Expect to configure backplate, wing, and harness separately rather than buying a fixed jacket.

"Lift capacity" is the manufacturer-rated buoyancy the wing/bladder can provide at the surface. Match it to your exposure suit, tank, and weighting, not the biggest number available.

Pros
  • Stainless steel backplate adds ballast at the shoulders, which can reduce the amount of separate trim weight needed
  • 1000D Cordura outer shell with a 500D Cordura inner bladder is built for abrasion resistance in technical diving
  • Five D-rings across the shoulders, waist, and crotch strap give ample attachment points for stage bottles and reels
Cons
  • The stainless steel backplate is heavier to travel with than the aluminum-backplate version Scubapro also offers in this line
  • No integrated weight system, so divers need a separate weight belt or the backplate's trim-weight mounting points
Diver community sentiment
Mostly positive

A long-running Scubaboard thread on Scubapro's redesigned S-Tek line generally welcomes the changes, divers like the reworked stainless backplate, the Ergo nut hardware, and that components stay cross-compatible with older S-Tek and STA gear. The most common gripe is the stock webbing, which several posters describe as too soft or limp compared to the stiffer webbing used by DIR-style competitors, with some buying aftermarket webbing as a fix.

Scubaboard: S-Tek line impressions

Summarized from public forum discussion (Scubaboard, Reddit, and similar), not a survey we ran ourselves. See the linked threads for the original conversations.

The S-Tek Pro System pairs a 3D-formed stainless steel backplate with a 40 lb/18kg donut wing and a TEK LOC harness, aimed at technical divers running single-tank configurations. It’s built from a 1000D Cordura outer shell over a 500D Cordura inner bladder, with five D-rings, an argon-bottle mounting point, and a built-in carry handle on the backplate. It’s positioned as a technical alternative to recreational jacket and back-inflation BCDs, without an integrated weight system of its own.
