The Xstream second stage has a well-proven construction with a number of newly developed characteristics. The inner volume, so called dead space, is small, which enables the build up of carbon dioxide to be minimized. At inhale and exhale the resistance is minimal, e.g. 0.07 Joule at inhale at 150 meters (app. 495 feet) depth. The exhalation diaphragm is protected by a cover that can be removed without using tools for easy access to the diaphragm. The diaphragm’s position on the second stage also prevents flowing water from finding its way in to the valve.
Xstream Deco is made especially for the deco-stop where you are guaranteed that you can use as high as 99.95% oxygen. To never be confused with other gas mixtures, e.g. nitrox, the color-coding is in distinctive white for oxygen on the Deco first and second stage. By that you are also certain that the first stage has the wheel mounted in the bottom to fit oxygen optimally. Besides this, Deco is O4-safe, i.e. Oxygen engineered, Oxygen compatible, Oxygen clean, Oxygen approved. The number of outlets is minimized to two for maximum safety. As standard, the second stage is equipped with neck straps. The regulator is delivered with an LP-hose offered in a range of lengths to choose from.
