A second stage regulator must translate natural breathing behavior into mechanical reality. A high quality second stage can significantly reduce stress and enhance diver safety by providing smooth, low-effort breathing response, resulting in ample yet controllable quantities of air.

The human breathing process is unique and individual, rather intuitive, and taken for granted at the surface. However, once underwater and dependent on a regulator, we suddenly realize how personal and unique breathing behaviors are and how important a regulator can be. The harsher the diving conditions, the higher the flexibility and response we demand from a second stage regulator. This is why at SCUBAPRO we have implemented diver adjustable functions on many of our regulators.
