Cressi XS2/AC2 Piston Regulator Features

What's in the box: First and Second Stage Regulators and Low Pressure Hose

The XS2/AC2 Regulator is an exceptionally dependable non-balanced Flow-by-Pistondesigned 1st stage Regulator that is a great choice as a new divers rig, or for use as a stage bottle regulator system. The Second-Stage housing is made of durable non-corrosive hi-tech polymers, and has a dependable downstream demand valve mechanism. The flow of air is channeled to the mouthpiece by injection, creating a venturi effect enhancing the performance. The 2nd stage comes with a flow deviator that acts on the Venturi effect, with dive/pre-dive function.
