Thank you for the informative run through of the Mark 19 Evo regulator and the other tidbits of knowledge. The Mark 19 Evo is impressive and the small details that Scubapro went to improve performance over the Mark 17/19 non-Evo is interesting.
The Conshelf is dirt simple but it's tight IP spread from full to empty suited the USD/AL 1085 series downstream seconds well. And it needs little in the way of tools to service and has relatively simple parts for a diaphragm regulator.
The R109 exhaust is exhausting and gives me a headache .
