Poseidon Xstream DEEP MK3

Poseidon Xstream DEEP MK3

The objective; design the most reliable HP valve in the world. Every engineer knows the benfits of using balls in valve arrangements, since they will never be misplaced and will always end up in their perfect position. Unfortunately, varying upstream pressures will either push the ball too forcefullly into the seat or leave it unsecurely loose, giving unbalanced characteristics.

By inventing the oating seat (which automatically repositions the ball) the increased upstream pressure is balanced equally with increased and counter-acting compression forces from the pressure adjustment spring, maintaining the benefits of having a perfect ball as the sealing element. The Xstream regulator is also self-balancing, which gives the same high performance irrespective of the pressure in the cylinder. When the seat is moved upwards by the high pressure, the design causes the upper pressure spring to compress and thus exactly self-balance the powers of pressure.

Xstream also 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.

Product information

The benchmark for high performance regulators. Whether you dive with air, trimix or oxygen, the Xstream range outperforms all other regulators. First regulator certified to 200 m / 656 ft.

Thanks to its durability, reliability, high performance and excellent breathability in any environment, the Xstream is the regulator of choice for the US Navy, US Coast Guard, NYPD and anyone who prioritizes a safe, successful and serene dive.
