Poseidon Jetstream / Odin Octo Octopus 2nd Stage Regulator Yellow EXCELLENT!

Poseidon Jetstream / Odin  Octo - 2nd Stage Regulator  Yellow for High Visibility  36" Hose  FAST Shipping from USA!  Called an upstream 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, you hear a swooshing" sound of streaming air. The system is then activated. On 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. The regulators bladder-valve then collapses and in turn lets an amount of gas out, corresponding to the actual demand. This technology ensures that the lightest possible effort can result in an almost limitless amount of gas on inhalation. All-the-more astonishing is the fact that Poseidon introduced this technology to the market as far back as 1981. 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 breathe normally in the unlikely event of abnormally high-pressure air being delivered to the second stage.
