Diving Regulator SR2 - Atlantis

The Sherwood SR2 Atlantis is a contemporary, high-performance diving regulator built with cutting-edge materials and engineered to deliver superior breathing performance at depth. Designed for divers who demand reliability and comfort, the SR2 combines a truly pneumatically balanced first stage with an ergonomic, weightless-in-water second stage for an effortless dive experience.

First Stage

The SR2 first stage uses a unique two-piece flow-thru-piston design that makes it one of the only truly pneumatically balanced first stages available. A Sealed Dry Spring Chamber (SDSC) protects internal components from the marine environment, extending service life. The marine-grade chrome plated brass body offers excellent corrosion resistance, while the generous port configuration provides flexible hose routing for any setup.

Second Stage

The second stage features a pneumatically balanced design with a SMART demand lever and floating crown that relieves load on the seat, significantly extending seat life particularly during storage. An improved flexible purge cover, single-adjustment point, and a control knob optimised for easy location and operation make the SR2 straightforward to use even in challenging conditions. The ergonomic shape and near-weightless feel in water keep fatigue to a minimum on longer dives.
