Exactly. Unless you have bottom of the line regs, it's unlikely you will get better ones, assuming yours are serviced and quite possibly downgrading instead. New does not mean better. What are your current regs?
We both have a Mares Voltrex. We also recently switched to Nitrox. I was thinking after 25 years, that we should update our hoses and maybe also the regulators. I guess I just assume the reg might be wearing out. We have had them serviced a few years, but not every year. What do you think?
