My wife's Proton Ice 2nd stage was overhauled maybe 45 dives ago, and is now hissing a bit. She first noticed it on a trip in May. The guy in the dive shop there removed the hose, adjusted something. Maybe better, but not quite fixed. Got back home, where we have no Mares service. The go-to guy for equipment repair around here did some sort of adjustment. In the pool the next week, and on the surface, still a bit of hiss. The IP was about 140 (spec is 145 +/- 3 ), no creep. When I turned it down to 130psi, no hiss and little tendency to continue after purging.
So, the question is, is 130PSI too low, vs. the Mares spec of 142 - 147?
