Dumping fake problems on a diver with 5 dives in doubles, while futzing with a flooded mask and a deco bottle isn't teaching anything.
How do you know?
Teaching proper procedures FIRST prevents a "crisis" from happening.
Not always. Some things that happen in diving are unexpected.
"Surprise" out of air situations are silly and dangerous. I had that done to me in one of my classes, and I didn't get much out of it. I got much more out of being air-gunned and responding appropriately to it.
I got a lot out of it. Airgunning, I did not find stressful. To each their own... people learn in different ways.
Your initial post was to condemn the instructor and to say that turning off someone's air will lead to panic. Given you do not appear to be a technical diving instructor, nor have much experience with stress testing, I thought it was a bit harsh and not true across the board...
