Agreed. People can Armchair Quarterback the buddy’s decision all they want. At some point, you’re going to have to make the call to ascend.
The deceased was found inside of the wreck. Are you proposing that someone with only an AOW cert and no wreck penetration experience follow someone inside of a wreck in a situation like this?
No, not at all. The point of my post was that we crank out AOW divers with very minimal training for deep diving (a cursory review of some relevant info and one deep dive), and then we pretend they are qualified to handle a dive like the Vandenberg... with typically strong current at a depth of 110 ft. Training that includes "what if" scenario discussions, so that AOW students are aware, before getting in the water, of all the little things that could go wrong would be beneficial.
To your last point, we discussed that during my AOW course. It’s one of the reasons I carry a pony bottle.
I know there are instructors that go beyond standards and understand the bigger picture. Sounds like yours was one of them!
