SCUBAPRO MK25/S600 Regulator 232 Bar A Clamp

Posted by Grahamne Muir

Our top performing balanced piston first stage paired with our high performance air balanced second stage; this combination is SCUBAPRO’s most popular regulator combination.

The S600 truly matches the MK25’s characteristics and thanks to its adjustment possibilities, it adapts to all diving conditions and all diver preferences. Ease of breathing is the essence of this system.

The MK25 first stage is a superior regulator thanks to its ultra stable intermediate pressure resulting in an extremely punctual and constantly high delivery of air. The means instant air flow at any cylinder pressure and water temperature for a real carefree dive. Paired with the air balanced high performance S600 second stage, this system is our top performer.

The balanced flow valve provides constant and effortless air flow and the diver adjustable inhalation control enables personal adjustment of breathing effort.

With diver adjustable Venturi Initiated Vacuum Assist (VIVA) dive/pre-dive control switch and an extra high flow exhaust valve it allows for easy inhale and exhale.

It also has a super-flow hose for smooth air delivery and the precision moulded, lightweight components and anti-freeze materials provide high corrosion resistance and enhance cold water performance.

SCUBAPRO MK2 Plus/R295 Regulator A Clamp

Posted by Grahamne Muir

The classic downstream piston configuration is the simplest mechanism that exists to control the pressure drop from a tank to feed the second stage.  The classic downstream valve is the first choice of diving centres and rental facilities worldwide for warm and moderate water temperatures.

To ensure worldwide compatibility, all SCUBAPRO regulator systems are available in a 200bar INT version as well as 300bar DIN versions.

Classic downstream valves are particularly noted for their legendary safety and reliability.  When in use, the downstream valve opens in the same direction as the incoming air flow.  To close the valve and stop the air flow, a spring counteracts the force of the incoming air.  Therefore, a certain inhalation effort is always required to overcome the spring tension and open the valve.

The Fixed VIVA (Venturi Initiated Vacuum Assist) flow vane is fixed in the pre-tuned ideal position for safe and uncomplicated use.  It is extremely lightweight and compact making it comfortable for all divers, including novice divers newly initiated in the sport.

The SCUBAPRO uses a comfortable orthodontic mouthpiece on every second stage to reduce jaw fatigue and gum irritation.  It was developed by dentists and dental laboratories and lasts longer than any other mouthpiece, because only a minimum effort is needed to hold it comfortably in place.

Poseidon Octopus Cyklon

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.

Performance when you really need it! Our second stages has no up or down, which means that you will always be able to clear it from water.

It has been out in the field for over 45 years and experienced most of the things that can happen under the surface.

Jetstream Mk3 octopus with a 9/16 connection.

Delivered with a 90cm hose.

May only be used with a 1st stage that has a built in over pressure valve!

Did you know…

That all Poseidon Octopus are always of the same quality and make as our regular second stages, something that is rare with other manufacturers but obvious to us.

Poseidon Jetstream Mk3 Regulator

Posted by Grahamne Muir

The Jetstream Mk3 is an updated version of the classic Jetstream regulator. We have now connected a Jetstream second stage with an Xstream first stage, thus creating a high performing regulator.

The over pressure valve is now built in to the Xstream first stage allowing us to remove the over pressure valve from the hose. We have also changed that thread on the second stage hose connection to a standard 9/16 thread.

Delivered with a 70 cm hose.
