Product Description



A first stage from Apeks, this is a high performance 1st stage suitable for UK and technical diving.

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.
