Wow! Didn't know the viz was that low at the bottom. I figured it would be dark, but low viz as well.
The students were under the supervision of an instructor, a divemaster, and a divemaster in training. Their max depth was to be 80 feet
And from discussions overheard in the EMS circle, they will be formulating a more solid rescue plan as well. So something good is going to result from this event.
Just to stir up the pot, it appears that the instructor was not exercising good judgement by utilizing an improper venue for training the level he was training. You don't take OW advanced students to a 150 ft cold, dark hole for a class with a max depth limit of 100 ffw. Things can and always do seem to get out of hand.
I see little wrong with four students at depth in warm, clear water, but cold, dark quarries is another matter. Control is lost the second one of your wards decides he has had enough and as an instructor, it is always about control. We are responsible for our student's welfare.
..... Vis was maybe 3 ft max on the bottom with cannister lights....
i was the divemaster during that incident.
