REGULATORS AND ACCESORIES

If you are interested in any of the products below, please contact us for our competitive pricing.

POSEIDON XSTREAM REGULATOR

DEEP MK3

The Deep Mk3 in the classic Poseidon black and yellow. Suitable for air, nitrox 50% and trimix. Certified down to 200 m / 656 ft.

OCTO

 The Octo has the same characteristics as the Deep Mk3, but in bright yellow. 

DURATION

The Duration is the Xstream regulator suitable for use with pure oxygen. Easily recognizable by its green color. 

BLACK

The Black edition keeps it clean and professional. XStream is the preferred regulator by the US Navy, US Coastguard and NYPD. 

XSTREAM RANGE

A patented ruby ball seal is automatically positioned by the floating seat which balances any upstream pressure equally with the pressure adjustment spring,  This makes the Xstream Range self-balancing, giving the same high performance, irrespective of the pressure in the cylinder.   Added to this the range has a built in anti freeze protection in its construction. The TDA  ensures that the through-flowing water keeps the ice away, entirely without fluids or extra diaphragms. 

XSTREAM BLACK

The Poseidon Xstream Black has turned the best functioning regulator on the market into the best looking one as well. This self-balancing and utterly dependable regulator will have you respiring restfully and appearing downright awesome. 

POSEIDON CYKLON REGULATOR

CYKLON X

Robust, high performing, easy to use and cold water ready. The Cyklon just works. Now updated to X with the Xstream first stage and you have a regulator that will last a lifetime. 

POSEIDON JETSTREAM REGULATOR

Jetstream

Controlling the power of a massive air flow, astonishingly reaching some 2100 litres/minute is an engineering challenge. The solution to this was to obtain a precision regulation, keeping breathing pressure to within +/- 5 mm.w.c throughout the inhalation cycle, regardless of depth and demand. Called a servo-assisted valve, it works in the same way as does the power steering you may have on your car – it’s all about compensation.
