Something funny my regulator did last weekend

[DiverQueen]

Hmmmm now, that really stirred up the hornet's nest didn't it!!

So Todd, when you say the shop checked out the reg when you brought it back....Did they check it out with the first stage that was involved in the "O" ring damage, or the first stage that they replaced it with for the rest of your dives?  One of the down sides of rental gear is that "Who used it last and with what kind of care?" 

Even my spare gear gets the same kind of care, rinsing and annual maintenance that my "Personal and Primary" reg set gets!
