About Poseidon XSTREAM Deep MK3 DIN Regulator, Black

This is the regulator of choice for any demanding divers that dive with AIR or TRIMIX with a maximum of 21% oxygen. Outstanding performance and certified to 656' (200 meters)! The XSTSTREAM Deep MK3 Second Stage is a High-Flow Design providing 76 Standard Cubic Feet per Minute (SCFM) Flow of Gas (2,150 liters per minute). The 2nd Stage Regulator uses an Upstream Servo-Valve Design with a Safety Valve Opening Pressure of 261 +/- 14 psi (18 +/- 1 bar) Relief Pressure. The Second Stage has a Durable PVC Housing with Metal Mechanism and Rubber Parts. The Regulator has an Automatic VENTURI Assist and Inhalation Control.

The First Stage is a Balanced Rolling Diaphragm Ball Valve Design producing Extreme Leak Tightness. Conventional designs are Sensitive to Wear, Misalignment, and Manufacturing Precision. A Ball Valve always finds its correct place. Combined with the 2nd stage, the enormous capacity of the 1st Stage make the regulator meet the EN 250 Breathing Performance Requirements even at as low as 232 psi (16 bars) Cylinder Pressure. This means that you gain an extra 493 psi (34 bars) of Gas compared to most other regulators! The 1st Stage construction requires Less O-Rings than any other Regulator. The Hose Routing is developed to be optimized for a Redundant System, using Two-Regulators. The HP Ports are Positioned to Accommodate the use of Gas Monitoring Computers e.g. First Stage Mounted HP Sender/Receive Unit.

The 1st Stage has a Built-In Poseidon T.D.A, Thermo-Dynamic Anti-Freeze, which requires no maintenance. It is always there, doing the job. It is Thermodynamically-Protecting the Parts which Must-Not-Freeze. It is identified by the Large-Slots in the Cover, allowing the Heat Energy of the Water to Reach-the-Spring. The Cold from the Inside is consequently insulated from the spring, via an Insulation Barrier and Insulating Diaphragm. It is constructed without compromise to any detail to prevent cold reaching the sensitive area. Using Poseidon T.D.A, a Regulator can Free-Flow Air in Fresh Water of 32ºF (0ºC) for at least 10 minutes and afterwards still be completely unaffected. The 1st Stage Regulator is manufactured from Chrome Plated Brass. Regulator System comes complete with a 27.6" (70 cm) LP Hose. The XSTSTREAM Deep Mk3 comes with a Neck Strap; Owner's Manual and is covered by a 24 month limited warranty.

Questions about this item:

pete b  I would like to upgrade to the xtream deep. I am a recreational diver but would still like this reg. Will it work well/deliver gas with ease at lesser depths? say 50 to 80 ft range? is there a counter drag for less depth....thinking before i buy. your advise.
Michael C  There is no such thing as a counter drag in scuba. This regulator is designed for technical deep diving and so will actually perform much better at deeper depths, than it will at shallower depths. We do have regulators that will perform better for the type of diving you are doing.
