Poseidon Xstream Black Regulator

A high-quality regulator is essential for divers exploring various environments. Factors like inhalation resistance, exhalation bubble distraction, noise, and leak tightness should remain consistent despite changing conditions such as cylinder pressure, depth, temperature, or water type. When a new regulator enters the market, it must pass the EN 250 test, representing a single environment. While manufacturers may test more situations, only years of real-world use can guarantee optimal performance in every scenario.

The Xstream Black regulator is perfect for divers who demand versatility and performance, catering to Air, Tri-Mix, 100% Oxygen, and Nitrox right out of the box. Certified to 656 ft (200 m), this durable regulator is preferred by the US Navy, US Coastguard, and NYPD. Its unique design prevents current-induced free flow and obstructive bubbles, while its compact size and symmetry allow for easy use on both sides.

The second stage features a high-flow design, delivering 76 SCFM (2,150 L/min) gas flow, with an upstream servo-valve and automatic Venturi assist. The first stage employs a balanced rolling diaphragm ball valve design, ensuring extreme leak tightness and EN 250 compliance even at low cylinder pressure.

The black chromed first stage houses a built-in Poseidon T.D.A, Thermo-Dynamic Anti-Freeze, providing maintenance-free protection against freezing. This feature allows a regulator to free-flow air in fresh water at 32 Degree F (0 Degree C) for 10 minutes without any adverse effects. The Xstream Black comes with a neck strap, a 27.6" (70cm) LP hose, and an owner's manual, ensuring a reliable diving experience in any environment.
