I was thinking of you when I coded that in.
It's easy to be incredibly hard on these divers, but I think that's an injustice. Panic can happen in anyone, given the right conditions.
Thank you!
I remember reading a lot about the incident pit in the accident and near misses forum and your comments about stress got me thinking. Lets say that he starts at the top of the pit at the beginning of the dive. (I know that's debatable but bare with me.) On the descent he has two problems, his loose weight belt and mask flood. This pulls him deeper in the pit. At the end of his descent he manages to fix both problems; adjusting his weight belt and clearing his mask. Even with these two problems solved he is still not out of the pit like he was before the dive. The added stress and distraction of having had the problems in the first place may not have been completely clear of his mind, leaving him still partially in the pit. He then has another two problems, but he is now deeper in the pit than he was the first time, that much more stressed, and that much more in danger.
Everything you said about panic and knowing your limits is certainly good, but I think there is another good take-away or two from this.
Plan your dive and dive your plan. Deciding mid-dive to "attempt" (their words) to double your planned depth seems a little foolish.
Use the right gear for the dive:
A snorkel is not something that should be attached to your mask when you know you're going to be pulling yourself down a line against a current. If he had his snorkel in a pocket, or no snorkel at all, I doubt his mask would have flooded so easily. (Did he even use the snorkel on the surface?)
The St. Lawrence can get pretty warm. In August when the dive took place it could easily be over 70F. That said, even if you dont need gloves for warmth you'll still need them thanks to the zebra muscles, and whatever else might be stuck on the rope. I've never seen anyone up here in my short time diving, dive without gloves.
I didn't see an SMB on either of them. In the St. Lawrence with the boat traffic, I wouldn't dive without one. Then again, maybe they had one and just didn't use it.
It was definitely not a drift dive. Descent and ascent were both on the mooring line.
It can be done as a drift. Hop in at the moring line drift past, keep shallow and eventually get caught in an eddy and exit on either Sparrow or Stovin island (I forget which is which now). I don't think that's what this group was doing though.
