OK, here's one for you. I switched my primary from a Dacor Extreme to a Scubapro G250. I like the Extreme a lot, except it breathes a little dry, as non-metal regs often do, and it works less well after I put my 120 down on it. There's just one thing about this Scubapro: it breathes too easy for me. Now, it is adjustable, so I just crank it down and fix the problem, but I have to crank it wayyyy down, *well* past the point where any trickle of air stops. There's a wide band of adjustment where it just takes a little, too little for me, inhalation pressure (or a bit of water current) to get things flowing, and when the venturi is on, it keeps flowing. I feel like I put my mouth right on my tank valve. I've found I *like* a little bit of breathing resistance. With this reg, my air consumption is way up and my breathing pottern is messed up. I'm going back to the Extreme, but here's my question: can I / should I get used to low resistance regs? I've heard that a reg with high breathing effort is wasting energy and therefore air. Is it a significant amount? If I can find a breathing pattern that is used to less resistance, will I be using less air? #-------------------------------------------------# Roger Carlson 310-376-4437 h Somewhere off Hermosa Beach, Cal 310-812-0430 w rgc@co*.sp*.tr*.co* 310-812-1363 f #-------------------------------------------------#
