And the shrimp has a complicated diaphragm (the OC part) with multiple little bits and places for leakage
 
I'm just pointing out there are even more little fiddly bits in the OC side of a BOV that in a regular OC reg and that its a good idea to do an in water breath because of that

RB80 BOV = R190 but with a slightly smaller diaphragm. Simple as can be, even though it does look like a cub scout used a pocket knife to whittle it out of a chunk of delrin.

anyone switching them over to anything else?
 
Oh for goodness sake of course I wet breathe the thing but I was hoping to avoid the “You’re gonna die” comments from the peanut gallery! Actually I purge it first and then take a breath in the water.

Don't forget you need to say “Let's get ready to rumble” after that breath to check the helium content.
