The SR2 offers superior breathing performance which only few regulators achieve; less than 0.65 joules/liter of WOB* at 50 msw (165 fsw), & 62.5 l/min RMV*.

The SR2 is the ONLY Flow Through Piston Regulator that is both environmentally sealed and internally dry, and still o ers a depth compensation mechanism. This is no easy task to achieve. Sherwood’s patented Three Pin Link (3PL) transfers the environmental pressure to the piston and provides consistent flow at any depth.
