Couldn't agree more with John...I mean thanks for sharing your story and glad that nothing serious happened but I think the bottomline in general should be: "get the f*** off that loop" when you get a reading like that. Many others may have gotten to sleep already..
With the BOV fitted as standard bailing out to OC is too easy on the KISS...I've actually just gone to OC mode a couple of times on the surface at the end of a dive when I felt I had to work hard and couldn't be stuffed checking/maintaining a high pO2
VERY, VERY Good Point.
Actually, the very direct feedback I got from my instructor/friend was:
"What the heck were you trying to do, conserve ambient air?" meaning I could have just as easily closed the DSV and removed the loop from my mouth altogether - No OC, no BOV, just shut it down.
His point was that
I shouldn't have been on the loop once this started - I could have switched to OC or closed the DSV prior to making ANY move
All very valid points, and in the future, I will not let it be a problem by switching to OC if I'm on the surface for any amount of time.
