The SR3 provides superior breathing performance, in which only a few regulators in the world achieve. Less than 0.65 joules/liter of WOB at 50 msw(165fsw) &625. l/m RMV. The SR3 is the ONLY Flow Through Piston Regulator that is both environmentally sealed and Internally Dry while still providing a Depth Compensation mechanism. Which is no easy task to accomplish. Sherwood’s Three Pin Link (3PL) transfers the environmental pressure to the piston and provides consistent flow at any depth.
