Poseidon Jetstream MK3:

The Jetstream Mk3 is an updated version of the classic Jetstream regulator.

We have now connected a Jetstream second stage with an Xstream first stage, thus creating a high performing regulator.

The over pressure valve is now built in to the Xstream first stage allowing us to remove the over pressure valve from the hose.

We have also changed that thread on the second stage hose connection to a standard 9/16 thread.

Delivered with a 70 cm hose.
