XStream is the preferred regulator by the US Navy, US Coastguard and NYPD.
The most reliable 1st stage in the world. A patented ruby ball seal is automatically positioned by the floating seat which balances any upstream pressure equally with the pressure adjustment spring, maintaining the benefits of having a perfect ball as the sealing element without the risks that follow with incorrect sealing pressures. This makes the Xstream Range self-balancing, giving the same high performance, irrespective of the pressure in the cylinder.
Added to this the range has a built in anti freeze protection in its construction. The TDA (Thermo Dynamic Antifreeze) ensures that the through-flowing water keeps the ice away, entirely without fluids or extra diaphragms.
Poseidon’s deepest diving regulator, tested and approved down to 200 m / 656 ft with extremely light breathing.
A side purge prevents current-induced free flow and diverts bubbles away from view.
A unique design allows use from both left and right while keeping the regulator exceptionally small.
