OP
I was mostly looking at the 100% O2 concern, but if I get the XT1/XT2 kit O2 cleaned and ready then it should be okay to use for 100% and 50% O2.Why do people think that deco regs should be different from primary regs? In what ways should the be different and why? Other than saving cost, if you don't already have enough?
Is there a "standard" color for 50%? I know green is for 100% O2?
