As the diver descends the demand for air increases. To maintain the supply the intermediate pressure increases relative to the water depth. In this dry sealed system hydrostatic pressure acting on the outer sealing diaphragm is transmitted to the primary diaphragm via the load transmitter. This first stage utilizes a unique over-tracking (over-balanced) diaphragm design where the intermediate pressure supplied to the second stage increases more than traditional balanced models as the diver descends to greater depths. The result is superior breathing performance regardless of depth.
First stage available in both DIN and A clamp versions.
The DS4 first stage regulator has the following features:

Dry sealed system for cold water
No turret
4 medium pressure ports 38 UNF
1 high pressure port 716 UNF
