Questions about this item:

Shopper  Why Did You Choose This?
michael r  Leisurepro has just what I'm looking for at a better price them the local dive shops. everything is just a click away.
Shopper  Will this work with a hookah system?
TERRY G  I honestly don't know since I haven't used it on a hookah. I can't image why it wouldn't so long as the 1st stage pressure of the hookah is approx. 145 psi. But again, I haven't used a hookah in over 30 years and I'm not familiar with current systems. I've used it as a "save-a-dive/trip" 2nd stage and it was an excellent alternative, really nice breathing. Hope this helps.
Scott S  My current Mares 2nd stage broke. However, My hose and 1st stage are fine. Can I put this on my current reg set-up?
Joe S  It should work as long as it's a standard coupling thread
