We have now connected a Jetstream second stage with an Xstream first stage, thus creating an even better version of this high performing regulator.


The regulator of choice for demanding divers using air, nitrox, trimix or oxygen. Outstanding performance and certified to 200 meters / 656 feet.


Poseidon’s Cyklon set a new world standard for diving regulators. When it was introduced in 1958, the Cyklon was the first regulator in the world with a single hose and the demand valve situated at the mouth.
