Exact replacement Second Stage that comes in the MK19/25 EVO A700 system. For divers who just need the Second Stage alone, without the need of the full system.

The Scubapro A700 2nd Stage features a full metal housing that is designed to offer excellent cold-water performance as the metal construction allows the cold to be transferred to the surrounding water far quicker and more efficiently than normal plastic housings.

It also allows the diver to independently adjust the Venturi and inhalation resistance. The Venturi control adjusts the flow of air within the housing, directly it toward the mouthpiece for optimal flow or toward the diaphragm to aid in closing the valve.
