SR¹ high performance regulator is NOW AVAILABLE. With superior breathing performance of less than 0.5 joules/liter, W.O.B. at 165 fsw, 62.5 RMV, the SR¹ is the most technologically advanced regulator Sherwood Scuba has produced in its storied 50 year history.

The SR¹ utilizes a pneumatically balanced second stage, with a two-piece flow-through first stage piston for precise optimum balance and intermediate pressure control. The first stage is environmentally sealed featuring a dry-sealed spring chamber, two high pressure ports, five low pressure ports on a 360 degree swivel and is compatible with a yoke or DIN attachment. The second stage contains a SMART demand lever and floating crown which reacts to depressurization and relieves the load on the seat, extending seat life while promoting consistent performance.

Importantly, the second stage employs a unique single adjustment point to simultaneously set opening effort and high flow performance with one motion--the need to make separate adjustments has therefore been eliminated. The size of the SR¹ control knob has also been optimized to enable easy location and operation, even for a diver wearing gloves.

The SR¹ packs its advanced technology into a compact case which employs contemporary styling and utilizes a multitude of cutting edge materials.
