Rebreather Purchase question

[Inspirationdiver]

Free flowing regs on a CCR rebreather is really a non-issue. Sure, it can happen but it is really unlikely. The higher the gas flow through a reg, the faster it gets cooled and the more likely it is to freeze up. On a CCR, gas is only injected in small spurts. The only time there is any significant flow is during a fast descent. You have to add diluent to make up for the increase in pressure. Even then, the flow is comparable to when you add air to your drysuit. Most argon regs are unbalanced piston regs and don't have any problems under those conditions, even in really cold water. The Inspiration comes with the DS4 first stage ( balanced diaphram- same as the Apex TX50 first stage) which is a very dependable reg in my opinion.
