I don't remember being taught to take a breath and watch the SPG - could be my memory, could have been the class.
I have failed to check tank pressure before getting in the water. But I have NEVER, not once, failed to take 3 breaths from my primary reg and a couple from my backup, before jumping in. My Fundies instructor asked us if we knew how many breaths it took to empty our hoses. For me, it's four breaths on the primary, so I figure if my check totals at least four breaths, I'll find out if my gas is off. 99% of the time, I look at my SPG while I do it, to look for a barely opened valve.
