The Poseidon Xstream Duration Regulator is the Reg of choice for demanding divers using air, nitrox, trimix or oxygen. Outstanding performance and certified to 200 meters / 656 feet. The Poseidon Xstream Duration Regulator 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.
  • 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 into the valve.

Comes stock as a DIN Reg, but you can add a Poseidon Din Adapter if you want to use it on standard yoke tank valves.
