An alternate way for a sport diver to configure their regulator instead of using a yellow octopus at the end of a long, yellow hose. The streamlined set prevents hoses from dangling and optimizes comfort.In the streamlined configuration, the hose on the primary regulator routes under the diver’s arm and attaches to the second stage with a 90° swivel adapter, optimizing comfort because the hose is no longer tugging on your mouth. The backup regulator, inserted into a regulator necklace, is tucked safely under the chin, allowing immediate access. In an emergency, the primary is donated while the backup is instantly available. The SPG is clipped to the waist D-ring using the snap.FEATURES Vortex DIN First Stage  Two Vortex Second Stages  40 in (102 cm) Miflex LP Hose - Black 22 in (56 cm) Miflex LP Hose – Black Vortex Spin-On Yoke – Black Large Highland Black Silicone Regulator Necklace 90º Right Angle Adapter Highland 2 in (5 cm) Brass and Glass SPG w/ PVD finish - Dual Scale  24 in (61 cm) Miflex HP Carbon Hose) Highland 4 in Swivel Bolt Snap 22 in (56 cm) Miflex QD Hose

For both Warm and Cold Water Conditions.  - R8 BALANCED DIAPHRAGM 1st STAGE • It has a high-flow, fast-acting valve system that is capable of delivering large amount of breathing gas in an instant, irrespective breathing demand, cylinder pressure or depth. It has not only passed the stringent CE test but the performance is comparable with the best available. • 4 intermediate pressure ports (located in the swivel turret) and 2 high pressure ports. • Available with YOKE or 300BAR DIN (G5/8) connector. • Anti-freeze models are available Separately. • Inter. pressure setting @ 9.5~10.0 bar (137~145psi) • Ventilation rate @ 206 bar (3000psi): 3820L / min. (135 cuft / min.)  - O60 BALANCED 2nd STAGE The O60 second stage is equipped with a metal balancing tube and an adjustment knob. They are able to meet heavy breathing demand with ease and in extremely cold water they also act as heat sink to prevent icing. • Ease of breathing is achieved by a purposely shaped housing interior, which is designed to create a pressure drop in the area just before the mouthpiece. This means air gets pulled towards the diver’s mouth directly after leaving the valve. • The volume of air leaving the valve can be fine-tuned by the adjustment knob on the side of the O60 at any time so the diver can choose to to breathe conservatively, or to open the valve up for more air in physical demanding situations. • The pre-dive / dive switch next to the adjustment knob prevents the valve from freeflowing while on the surface. • The second stage comes with our high-spec, large bore intermediate pressure hose (max. service pressure @ 34.5 BAR / 500psi) which flows sufficient breathing air even when the demand is heavy. • Cracking pressure setting @ 0.8 ~ 1.2 inch of water • Flow rate @ 206 bar (3000psi): 30+ cu ft / min • Max service intermediate pressure @ 10 bar (145psi)

The Octopus XS2 uses the same casing as the XS2 model, the only difference being the yellow front cover.The hose is also yellow and is longer (100 cm against the standard 76 cm).All the mechanics are identical to the XS2 model and consists of a downstream side valve system, with adjustable orifice, simple and extremely reliable.A flow of pilot air is channeled to the mouthpiece by injection, enhancing the performance. The upper part of the body has a flow deviator that acts on the Venturi effect, with dive/pre-dive function.Constantly reviewed over the years, this regulator has lots of admirers in the world due to the fact that it is extremely simple and strong, features that make it easy to use and result in low-cost maintenance.In any case, performance levels are high, although the calibration is regulated so that the inhalation effort is slightly greater than on the XS2, to prevent any free-flow possibility when it is used as a spare regulator.The air supply pressure can be adjusted between 9 and 10 bar, perfectly suited to all the Cressi first stages.
