Atomic ST1 Second Stage Only, 32" (81.3cm) Hose, Gray
Product OverviewThe ST1 Second-Stage is a balanced linear flow design for extremely easy breathing at all depths and dive conditions. The ST1 Second-Stage is built to last with a titanium demand valve body, lever and sealing orifice. The diaphragm is made from high quality silicone rubber. This pneumatically balanced poppet second stage has Atomics patented seat saving dynamic orifice which unlike most second stage orifices is a floating valve design which reduces wear on the second stage poppet seat when the regulator is not pressurized adding Life to this important seal.
The ST1 Second-Stage Regulator is equipped with Atomics patented automatic flow control (AFC). This unique diaphragm activated vain automatically controls the flow and venturi-effect of the second stage for optimum breathing resistance at all depths. The second stage does have a rapid adjustment knob for rare special situations. If you have ever experience the pulling effect" of the regulator second stage when you turn your head underwater, those days are gone with Atomics Comfort Swivel. Perhaps one of the most admired features of Atomic Second Stages is the patented comfort swivel which allows 30° rotational movement without binding or kinking. The Regulator comes equipped with a 3/8" Threaded 32" (81.3cm) Low Pressure Hose. The Regulator weighs 13.16 oz. (373 g) with hose.
