SR1 Hi Performance Regulator

The SR¹ utilizes a pneumatically balanced second stage, with a two-piece flow-through first stage piston for precise optimum balance and intermediate pressure control. The first stage is environmentally sealed featuring a dry-sealed spring chamber, two high pressure ports, five low pressure ports on a 360 degree swivel and is compatible with a yoke or DIN attachment. The second stage contains a SMART demand lever and floating crown which reacts to depressurization and relieves the load on the seat, extending seat life while promoting consistent performance.

Importantly, the second stage employs a unique single adjustment point to simultaneously set opening effort and high flow performance with one motion--the need to make separate adjustments has therefore been eliminated. The size of the SR¹ control knob has also been optimized to enable easy location and operation, even for a diver wearing gloves.

The SR¹ packs its advanced technology into a compact case which employs contemporary styling and utilizes a multitude of cutting edge materials.

D.V.T. How Does it Work?

When your dive is finished, before the regulator is even removed from the tank valve, the Dry Valve Technology system is already closed, sealing out moisture and any other contamination.

The filter is safely positioned behind the moisture barrier to eliminate filter flow restriction due to corrosion.

DVT (Dry Valve Technology) is one of the greatest innovations in regulator technology in recent history. DVT is a fully automatic valve that protects your first stage regulator's internal components against the harsh water environment in which we work and play; with no impact on the regulator's first-class performance.

DVT provides an "automatic extra layer of protection" from environmental contamination such as dirt, dust, sand, spray, dripping and pooled water, or even a "flash flood" in a rinse tank. DVT improves performance and reduces service costs associated with corrosion of critical internal components, bacteria, hose deterioration, and damaged gauges and computers.

How Does It Work? Open the tank valve and air is delivered through a downstream system without restriction.

When your dive is finished, before the regulator is even removed from the tank valve, the Dry Valve Technology system is already closed, sealing out moisture and any other contamination.

The filter is safely positioned behind the moisture barrier to eliminate filter flow restriction due to corrosion.

If Harley Davidson built a Regulator, it would be a Poseidon

How Serious are You about Diving?

The Equipment you trust your safety to, says a lot about you. What does yours say?

Prices on Poseidon Regulators have been lowered for 2006. Now is the time to buy.

Xstream

Absolute air integrity in the first stage is a life determining quality for an extreme user. Because of this the number of gaskets and o-rings in the Xstream is minimized to the lowest possible. In the heart of the construction is a ball made of stainless steel that eliminates the most common problem, a leaking high-pressure valve. Another advantage of the ball is that it can never be dislodged, making risk factors such as misalignment, wearing out and other construction tolerances that can lead to leakage non-existant in the first stage.

Xstream Dive/Deep

As the name indicates this model is designed for those who dive deep with gas mixtures up to 21% oxygen. Depending on the area of usage and choice of configuration, the Deep first stage exists in two varieties; with the wheel mounted in the bottom part or from the side (Deep 90). The colour marking of the first and second stage is black (Trimix). The second stage is equipped with neck-straps as standard. The number of outlets are five LP ports for Deep 90 and three LP ports for Deep for maximum safety. The regulator is delivered with an LP-hose offered in a range of lengths to choose from.

Xstream Duration 90

This regulator is especially suitable for diving when you are spending a long period of time under water. Up to 50% oxygen can be used in the Duration that is O4-safe, i.e. Oxygen engineered, Oxygen compatible, Oxygen clean, Oxygen approved; hence the color-coding green for Nitrox in both the first and the second stage. Duration is also available in two varieties; with the wheel side-mounted or mounted in the bottom to fit your personal configuration optimally. Seven outlets on Duration 90 provide maximum safety. The regulator is delivered with an LP-hose offered in a range of lengths to choose from.

Xstream Duration

This regulator is especially suitable for diving when you are spending a long period of time under water. Up to 50% oxygen can be used in the Duration that is O4-safe, i.e. Oxygen engineered, Oxygen compatible, Oxygen clean, Oxygen approved; hence the color-coding green for Nitrox in both the first and the second stage. Duration is also available in two varieties; with the wheel side-mounted or mounted in the bottom to fit your personal configuration optimally. Just three LP outlets on Duration and five LP on Duration 90 provide maximum safety. The regulator is delivered with an LP-hose offered in a range of lengths to choose from.

Poseidon Xstream Deco

To never be confused with other gas mixtures, e.g. nitrox, the color-coding is in distinctive white for oxygen on the Deco first and second stage. By that you are also certain that the first stage has the wheel mounted in the bottom to fit oxygen optimally. Besides this, Deco is O4-safe, i.e. Oxygen engineered, Oxygen compatible, Oxygen clean, Oxygen approved. The number of outlets is minimized to three LP ports for maximum safety. As standard, the second stage is equipped with neck straps for Octopus. The regulator is delivered with an LP-hose offered in a range of lengths to choose from.

2 LP ports
1 HP port
Approved for 99,95% Oxygene
Delivered with an HP hose, lenght of your choise
White color coding

JetStream Black

MSRP $525

The construction’s simplicity guarantees high performance, as well as safety regardless of diving conditions. This gives you a regulator that is easy to breathe at any depth. The Jetstream second stage is equipped with a safety valve in case a high pressure airflow should occur. This safety valve prevents the airstream from flowing out through the mouthpiece straight into your mouth. The construction will instead, release the flowing air out into the water via the hose. In all cases it is possible to breathe from the second stage. Tests conducted by the American Navy show that the Jetstream is the only regulator that manages to deliver the correct amount of air at extreme depths and rate of breathing. Jetstream also won the Swedish Navy´s highest classification, well within the objective breathing test in cold waters. Jetstream is approved according to the EN250 cold water standard.

EN250 Cold water approved

CYKLON 5000

MSRP $560

The first regulator in the world with only one hose and the demand valve situated at the mouth, this was presented in 1958 and set a new world standard for diving regulators. Still this regulator beats most other regulators on the market with some considerable ease. The German Navy and many others still have the Cyklon regulator as their first choice, thanks to the well-tested construction and design. It has been out in the field for over 45 years and experienced most of the things that can happen under the surface.

EN250 Cold water approved
Used by German Navy
2nd stage in plastic

Atmosphere mask

The Poseidon Atmosphere full-face mask is equipped with one of the world´s highest performing regulators - the Poseidon Jetstream PP. It is approved for cold water and in combination with the mask, it features a unique highly effective de-fogging system which keeps the field of vision clear even at water temperatures close or equal to the freezing point. The mask has an anti-distortion visor, with frosted sides to prevent reflections.
