The XS Scuba Extra Air system is a redundant back-up air system for increased dive safety. A must have for solo divers or others who must be self-reliant underwater.
The Extra Air system comes with an optional-sized pony cylinder with a 230 bar combination DIN/Yoke valve. For the first stage, XS Scuba chose the compact DIN first stage installed with a Mini Tec pressure gauge. The second stage includes the XS Scuba Alt Air Octo connected to a yellow double-braided Miflex hose. All of this is mounted on a stainless steel pony mount bracket with a cam buckle strap with an anodized aluminum DIN inlet cap to seal out water and dirt.
System is Nitrox-ready with Viton o-rings.
