So I would like to gauge opinions.
When do you think it's appropriate to leave your buddy?
Is it appropriate for you to leave if your buddy has tons of gas but has some failures (primary light, for example)?
Or do you feel that team diving means staying together to help the team?
Do you dive with others but believe it's acceptable to leave them?
Do you let them know this before you ever get in the water?
saw this on Facebook but decided I wasn't going to respond there.
This is a loaded question with many loaded answers IMO.
First I think there is a point worth mentioning of "abandoning" a buddy, and "splitting up".
@ofg-1 told the story of how he had to abandon his buddy. I'm 100% behind that and while I'm sure those 15 mins were rather unpleasant, a single fatality is better than a double. His story has ended poorly many times, and if a perfect example of when to abandon your buddy.
There is another discussion about "splitting up" a team. I.e. you are on your way into a cave and 500ft in someone has a fairly significant gear failure. Say a HP spool completely shat the bed, regulatory started freeflowing, some other failure that is major enough to call a dive, but is only a major nuisance vs. something life threatening. Are you in a team of 3 and the one diver just turns around and waves the other 2 on? Do all 3 call the dive? What happens if you're 1500, or 5000ft back?
Are you in a team of 2 and the other guy is comfortable enough to solo dive and wave on or do you both turn around?
That to me is all dependent on the situation and the divers. I do a lot of teaching, which means I do a LOT of solo diving. My buddies also do a lot of solo diving and we are all comfortable and prepared to solo cave dive, and we all do on a pretty regular basis. I prefer diving with a buddy, but that's more for the social aspect vs. the "team" aspect. That all comes from many years of teaching and having to be fully self-reliant.
I will not "abandon" a diver unless my life becomes seriously threatened by staying with them.
I have no issue "splitting up" with a diver if the circumstances make sense and I am comfortable making the exit on my own. This is something that has been discussed with the divers that I'm willing to do it with and we actually have a specific hand signal for splitting up. The conversation usually looks like "*point at piece of gear with middle finger and make other obscene gestures*", "I'm OK", "Buddy split", "You go ahead", "I turn", "ok?"
If they are ok with it, then they signal ok and wave. If they are not ok with it, then they say "no", "buddy together", "turn".
The list of people I'm ok with that process though is VERY small and if I'm not diving with them, then the conversation doesn't even come up.
Controversial? Obviously, but it works for us. Last example of it happening was last month. Had 2x teams of 2 doing the same dive. One of them had a CCR issue and it wouldn't pass the 1.6/20ft check. He waved us on and we finished the dive as a team of 3. He stayed in the Blue Room for a few minutes trying to sort that out, but we were already past the sign by the time he was on his way out. That obviously is much less extreme, but we have had a few other dives over the years where one bailed at 500-1000ft and exited on their own. Don't think it's ever happened where a solo diver continued on, in that case it's always been to just turn around together. If we're a good ways into the dive though, usually it's just a "turn" signal.
In open water, I pretty much only ever solo dive or I'm teaching so the situation never really comes up.
