The Cyklon has been the first choice of many since 1958
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.
Thanks to its welltested construction and design, the Cyklon is still the first choice of the German Navy.
With its unique style, multiple colours and rugged reliability, the Poseidon Jetstream First Stage Regulator is ideal for beginners and experienced divers alike.
Effortless breathing at any depth. The Poseidon Jetstream First Stage incorporates a safety valve that allows you to continue to breathe normally from the second stage, even in the unlikely event of abnormally high-pressure air in the first stage.
The benchmark for stellar performance, the Xstream is the regulator of choice for divers using air, nitrox, trimix or oxygen. The regulator of choice for the U.S. army, the Xstream has been certified to 200 m / 656 ft.
