It’s a good thing your regs aren’t Scubapro’s that you’re throwing away. Mention that around here and you’d have riot on your hands!
Well, to repeat myself, there are old regulators and then there are Scubapro regulators. Oh, and the exception, that being the USD/AL 1085-XX. As to Microns, old, new or in between, meh. But, I doubt there is anything on those that needs replacing that is not available but some folks just got to have new thinking that new is better though quite often it is not.
