Poseidon Jetstream MK3 Black

Effortless breathing at any depth. The 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 inhalation membrane won't cause a free flow in a counter current or when riding a scooter, which is a huge advantage of having the purge button on the side. It also gives the diver a freedom to select if the hose comes from the left or right without serious performance limitations.
