“Emergency cord pulled” issue I have is this action most likely did not cause a uncontrollable rapid ascent. At only 2 atmospheres back in the late 1960’s these cartridges on bcd or horse collar vest’s barely inflated enough to cause type of rapid ascent described.
Correct, however those things were phased out some time around the ‘90’s, or so, as my best guess. Either there was some old gear being used, a misunderstanding in the quote, or the writer was having flashbacks.
Is there a medical event that quacks like narcosis? What could make someone swim off like that?
He could have seen something more interesting to him, not necessarly fueled by narcosis, or he was having some kind of issue, real or imagined, and that seemed like a good solution.
There's a theme this incident brings to mind. A recurrent criticism of the dive industry by a few has been that recreational diving is billed as 'safe,' without enough emphasis on how dangerous it is or can be. Since the people educating the public are the ones selling dive courses and dive gear, it's an understandable concern.
I'm with @Marie13 on this, the instructors that train local divers that I have met have no problem pointing out the dangers involved in the sport. My OW instructor made it plain that he didn't want any of "his" divers dead on the NorCal coast because he neglected to prepare them for the dangers. Warm water is selling the pretty fishes, as opposed to perspective client going parasailing instead, pointing out the dangers is not good for business.
"The sharks, and the instructor diverting people’s attention to them before buddying up, “disrupted the whole process,” she said." That ought not to 'disrupt the whole process.' Of course a guide will point out the sharks.
This, right here, seems to be the start of a lot of issues. A dive proffessional says it's better to give up the buddy system so he can get his crowd down on his schedule, the divers listens to the professional, and things start going wrong.
Everything conspires to "disrupt the whole process", the idea of dive training is to first track your air, depth, time, and buddy before anything else, as that is how one stays alive underwater, then you can add the fun inbetween the reality checks.
