I'm selling Poseidon Jetstream that was used as a backup regulator on my double-tank setup during the past 2 years. Since the primary regulator never failed, this was only used during the so called "S-drills" or lift-bag shooting for a minute or two.

I am the first owner, and recently it has been serviced.
I have a new regulator setup so this one needs a new owner for years of safe diving.
