On our last dive in Coz and in fact on the dive where my wife caught the video of the Eel attacking the diver, she had an incident. It is all too familiar and y'all have heard it many times all the way back to OW class. Just before splashing, she or the deck hand on the boat closed the already open valve and then cracked it back a quarter turn. The problem became apparent a few minutes later at 35 feet when she found it difficult to breathe normally. She never panics underwater and this time was no different. She reached back to open her valve but realized it would take some effort to reach and rather than struggle and raise her activity level and gas demand, she yelled at me. I heard her and looked over. She calmly pointed at her valve. As I moved towards her, I looked down at my Perdix AI, as I monitor her tank pressure on the bottom right of my screen there and saw a critical pressure warning. This is set at <350 psi. I immediately thought, "crap her valve is closed" and reached over and opened it. She gave me an ok with a look of "thanks buddy" and swam on as if nothing of consequence had happened. I found that to be quite comforting in that she thought clearly, I thought clearly, we worked together without any hesitation and carried on. We went on to have our most fun dive ever.
There are obviously lessons to learn, all of which we have heard many times;
*be responsible and thorough, never leave anything to someone else
*Stay close to your buddy, especially early and late in the dive
*Always be able to reach your valve
*Always open the valve all the way, never back it off a bit like you were
taught in OW, this bears repeating
*Never panic, think, breathe, stay calm, act
*Stay humble
Oh and the Perdix AI is a really cool tool for those that like really cool tools.
