Promate Scuba Dive Octo Shut Off Valve Freeflow Control Device - PI001

A fabulous addition to keep an Octo adjusted to super light vaccuum...or even slight free flow without worrying about losing any air in standard dives. A must for avoiding free flows of any (including cheap) second stage.

works well

Looks like pretty good quality, will get it in the water and test. I will then update my review.

Great device if your regulators are not tuned perfectly and occasionally blow out. It's easy to install and easy to use. I was a bit worried that the valve might close accidentally if bumped against something but I have not had that issue yet. I bought two and put one on each regulator. Just make sure that any of your diving buddies know about the valve in case they need to buddy breathe.

Prompt delivery, excellent seller, good product. exactly what I needed for leaking Octo.
