The regulator of choice for the most formidable of divers. The Xstream works with air, nitrox, trimix or 100% oxygen. Certified for use down to 200 m / 656 ft, this regulator never quits, giving it the honored place as the US Navy's, US Coastguard's and the NYPD's preferred regulator. There is no other way to put it - the Xstream has earned its name.

Suitable for air, nitrox 40% and trimix. Certiﬁed down to 200 m / 656 ft.
THE BENCHMARK FOR HIGH PERFORMANCE
The Xstream features technology like non other. Taking advantage of a side purge, current-induced free flow is prevented while at the same time diverting bubbles that would otherwise obstruct the divers view. The regulator's small size keeps it out of the way while its symmetry allows use from both the left and right side.
The objective; design the most reliable first 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.
the worlds toughest
Poseidon Xstream first stage has a built in anti-freeze protection in its construction. TDA (Thermo Dynamic Antifreeze) ensures that the through-flowing water keeps the ice away, entirely without fluids or extra diaphragms. No extra environmental sealing required.
Poseidon is one of few manufactures with mouthpiece regulators approved for cold water service by US Navy.
All regulators are EN250 (cold water) approved.
