Well I absolutely have to have one now.The Mark 2 Evo has three O-rings now, the additional O-ring seals the replaceable orifice plus the two on the piston. The only thing the Mark 2 Evo has in common with the Mark 2(and 2+) is the name and being an unbalanced flow by piston design. It is really a new regulator, even the ambient ports are enlarged.
I’m just thinking long term for when the Earth darkens, parts for everything are gone, companies are OOB, there will be no dive shops left, hell on Earth!, but I’ll have my compressor, my steel 72’s from the 60’s, and my MK2’s hopefully with enough kits for a lifetime….and my plates.
