Just a random update... I make it a habit to do a bubble check (equipment check) with my buddies on every dive. The other day diving with my 13 y.o. and a friend of mine that only has a handful of dives past OW certification he motioned that I had bubbles where there shouldn't be, but didn't know if it was ok or not. Rather than bring us all up I doffed my rig, identified a tiny champagne bubble leak from the yoke interface (and decided it was no big deal for this benign dive), put it back on, signaled "OK" and continued the dive. My friend was impressed that it can be that much of a non issue to take your gear off, check/adjust something, and continue the dive all at depth. That's not to say I think I'm anything special, more to point out that it is that easy if you practice it.
