Poseidon Jetstream Bundle

The Jetstream: traditionally popular with technical divers as well as the Swedish and US navies. Easy breathing at any depth, the second stage incorporates a safety valve that allows you to continue to breathe normally in the unlikely event of abnormally high-pressure air being delivered to the second stage. Approved to EN250 cold water standard.

Controlling the power of a massive airflow, astonishingly reaching some 2100 liters/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. Prior to diving, when you pressurize the regulator, the main blue bladder valve is inflated with the interstage pressure, along with all inner volumes including the upstream side of the servo valve. When this is done a “whooshing” sound of streaming air is heard. The system is then activated. On an inhalation, the forces from the inhalation diaphragm easily overcome the light forces to crack open or “tilt” the servo valve and in turn evacuate all inner volumes.
