Yeah, well this idiot took the regulator COMPLETELY OUT OF HIS MOUTH FIRST. Narrowly avoided disaster. I was asked a couple of years after I got certified if I’d be interested in taking the PADI IDC and becoming a Dive Master. I took one look at the insurance requirements and cost and decided it just wasn’t worth it. Better to do it on my terms.
Vomit goes thru regulators pretty darn well. Although I did take it out after to wash my mouth and it out.
Still not sure why, was on 36% at about 102feet which is close to the limit for oxygen toxicity. Might also have been the 8 foot swells on the ride out.
