Poseidon Xstream Deep Complete Kit

Poseidon Xstream: Pushing the Limits, Without Compromise.

The Poseidon Xstream is not just another diving regulator; it's a precision tool born for the most extreme conditions. Chosen time and time again by the US Navy, the Coast Guard, and tactical rescue teams, it is the first regulator ever officially certified for diving to a depth of 200 meters. Designed for technical and sport divers who refuse to compromise on their gear. Maximum performance, zero failures.

Poseidon's Advanced Engineering: Why the Xstream is in a League of Its Own

• Ruby Ball Seal and Servo Valve: Instead of conventional pressure seats that wear out over time, the first stage relies on a smart spherical valve that "always finds its natural place" to ensure an absolute hermetic seal and prevent leaks. The real magic happens in the second stage, which is equipped with a unique Servo Valve. This technology reduces inhalation effort to almost zero (a mere 0.07 Joules), delivering phenomenal ease of breathing that feels completely natural—even under heavy workloads and at any depth.
• Upstream Mechanism and Built-in Over Pressure Valve (OPV): The second stage operates using a unique Upstream technology, providing a massive gas flow rate of 2,150 liters/minute. Because such a mechanism could lock up in the event of a pressure failure, Poseidon equipped the first stage with an automatic Over Pressure Valve (OPV). The result: absolute safety and a guaranteed continuous air supply, even in the most severe extreme scenarios.
• Thermo-Dynamic Anti-freeze (TDA) System: Forget about high-maintenance environmental sealing. The TDA mechanism utilizes water flow to naturally prevent ice formation. This regulator simply does not freeze.
• Symmetrical Second Stage and Side Exhaust: A smart design that allows for both right- and left-handed operation without the need for tools. The side exhaust port prevents "free-flow" against strong currents or when using a DPV (scooter), and keeps bubbles completely out of your field of vision.

Technical Specifications:

• Certified Depth: 200 meters (strict NORSOK standard).
• Compatibility: Air, 40% Nitrox, and Trimix (Out of the box).
• Ports (First Stage): 5 LP ports and 2 HP ports for optimal routing, ideal for advanced setups.
• Cold Water Compatibility: EN250 standard approved.

Who is it for? The Xstream is not for those looking for shortcuts. It is designed for those who push the limits and demand absolute peace of mind from their equipment.
