Ahh, harassment training… I miss the old days of scuba training.
AFAIK this was also typical training on many civilian classes; at least it was on my class. Then again, maybe it had a bit to do with my instructor (Harry Hauck) being and ex-UDT trainer.
As a kid, being very comfortable in the water, this kind of training was a lot fun. We also did other fun training, like covering the inside of our mask with aluminum foil and find our way around the pool and try to orient ourselves by sound (not very effective).
Another fun game was putting four tanks with regulators on the four corners of the pool and playing musical chairs with four divers. We all had to coordinate together so we all move to the next station at the same time, or someone was going to be without a rig.
When I did my training we were using single hose regulators. The instructor (or assistant instructors) would wrap the hose on the back, but no actual damage was done by making it too tight.
Well, there was one tike that I witness another assistant instructor not only turn off the air of a student, but also loosen up the yoke… that was not a good idea since the regulator flooded.
