This accident exposes a great weakness in the buddy system. In training, a lot of time is spent stressing the buddy system and how it’s not safe to dive alone. Almost no time is spent discussing what to do when the buddy system fails.
I know... I know... search for your buddy for 60 seconds and surface. That doesn’t work on deep dives with current or in a wreck.
It’s a little bit contradictory to tell open water students that it’s not safe to dive alone and then tell rescue divers to save themselves. The OW student doesn’t know his rescue diver buddy has been trained to abandon him when it gets dicey.
(Not saying that was the case here, but someone mentioned it.)
There needs to be more of an effort made to develop protocols for buddy diving failures so that both members of the team know what to expect. And, to help divers make the best decision when the time comes.
It would also reduce the second guessing afterwards and help the diver that has to live with the outcome to know he made the right decision.
The buddy system sometimes gives divers a false sense of security and they push farther than they would if diving solo. Most divers wouldn’t go inside a wreck if diving alone, probably wouldn’t go as deep either. But, having another diver with them emboldens them.
Unfortunately, dive agencies are so committed to the buddy system, they can’t acknowledge its weaknesses. So of course, they don’t want to spend time discussing what to do when it doesn’t work.
