With all due respect.... I don't think you could get to 300ft without realizing tht something was terribly wrong.
At about 165 I can "hear" that I'm pretty darned deep.... I don't know if you can follow that but anyone who has dived at those depths on air knows what I mean. I've been to a little over 200 on air and was thoroughly bonked.
If you ask me there's no way you could get to 300 by accident without being well aware that you had landed in a sh.t storm from here to Tokyo.

Diver0001: He may have reached 184 feet (per what was recorded on his computer) intentionally, but from there may have totally "lost it" to narcosis and descended rather quickly without being 100% aware of it.
I've been that deep on air too (in the 200' range), and like you said Diver0001, each time I was also near-totally "bonked" by narcosis :shocked2: . It took massive concentration to hold my depth because I was still "mid-water" at that depth, looking into a blue abyss with nothing for depth reference as I waited as a safety diver for another diver going, well,
deeper. All I had to look at was the bubble trail from the "deep" diver.
Despite the effects of heavy narcosis, my personal experience was that you do have "moments of clarity".
In the accident we are discussing, I could envision an "Oh My God" moment, a frantic jab at the inflator button, and an uncontrolled ride to the surface, all while heavily narc'ed. The difference with this happening with a more experienced diver would be the experienced diver would "hopefully" be thinking "gotta slow down at 100 feet, gotta stop and deco before I surface".
Best wishes.
