The XS Compact AC2 Regulator weighs 35 oz (994g) with hose and comes with an owner's manual. Large soft purge cover allows easy clearing of 2'nd stage and a comfortable silicone mouthpiece for breathing comfort. The 2'nd stage comes with a flow deviator that acts on the venturi effect, with dive/pre-dive adjustment function. The flow of air is channeled to the mouthpiece by injection, creating a venturi effect enhancing the performance. The R1 Harness System uses Traditional Squeeze-Style Buckles and Adjustable Straps on the Shoulders, Chest, and Waist for Precise Adjustment and Fit. The XS Compact Second-Stage housing is made of durable non-corrosive hi-tech polymers and has a dependable downstream demand valve mechanism. The R1 Diving Gear Package includes a Cressi R1 weight integrated BCD, Cressi AC2/Compact regulator, Cressi Compact Octopus, and the Cressi Leonardo Air/Nitrox Dive computer. A conical filter is used which has greater surface area for higher air flow characteristics through the 1'st stage regulator. This simple yet fail-safe design will deliver air even if there is a first stage failure.The 1'st stage has 1 high pressure (HP) 7/16' threaded port and 4 low pressure (LP) 3/8' threaded ports and is made from marine grade chromed brass for long life and durability. The XS Compact AC2 Regulator is an exceptionally dependable non-balanced flow-by-piston designed 1'st stage regulator that is a great choice as a new divers rig, or for use as a stage bottle regulator system.
