I bet a bunch of good buddy skills can be learned in a dive or two with someone like Bob, or with his team ... just by watching a good example

Ah ... nice way to start a conversation ... delegitimize opposing thoughts by labeling them "dogmatic" and "politically correct" ...
... you call that critical thinking? Sounds to me like you aren't open to any thoughts except those that agree with yours ...
Well ... I'll give it a go anyway ...
Yes, the reality is that the buddy system does fail - on a reliable basis. But it doesn't have to. Being a good buddy doesn't take special skills ... all it takes is learning the things we (instructors like you and I) are SUPPOSED to be teaching in entry level OW classes ... and a desire to do those things.
I disagree. I dive, and teach, in limited visibility conditions routinely ... conditions such as were described in the article (10-20 feet vis) are typical here ... with vis of 5 feet or less fairly common in summer months. And yet the vast majority of our divers ... even our new divers ... manage to maintain buddy contact.
What causes the breakdown is that the typical OW student is told that they should always dive with a buddy, but they're never actually taught how to do it.
That's exactly the sort of thinking that gets people hurt. What's the priority here? A chamber ride will cost you way more than $100. In this case, it cost this diver the ability to dive again ... EVER. Think he'd be willing to pay $100 to get that ability back again? I do.
Yeah, sure, it's painful to call a dive when you've spent big bucks to go somewhere special and bottom time is important. But your health and safety needs to be the priority ... always.
No ... it isn't ... not if you have learned how to keep track of each other, and have a will to make it a priority in your diving. After a dozen or so dives ... once you've adjusted your mindset to MAKING it a priority ... it doesn't even require any extra effort.
That simply doesn't work ... the lead diver has no clue what's going on behind him, and is proceeding on the assumption that the trailing diver will be able to get his attention if there's a problem. In low vis conditions, swimming shoulder to shoulder works much better, because it allows both divers to maintain eye contact and communication by simply turning their head.
Well ... OK ... but now what you're basically saying is that your plan is to solo dive. Why bother with a buddy at all? And if you're going to plan your dive as a solo dive, then train and prepare to dive that way from the get-go. Don't make assumptions that you're diving with a buddy when, mentally, you're not.
That's why God created DSMB's.
Not necessarily so ... depends on what the current's doing. Generally, the current's going to be pushing both divers in the same direction at the same speed ... so they're likely to surface pretty close to each other.
Again, your priority here seems to be dollars above safety. I really don't understand that mentality coming from a scuba instructor.
I say could've been prevented by better planning, better buddy technique, and better decision-making.
Almost everyone I know ... and certainly any diver I train ... uses the buddy system quite successfully. And we dive in Puget Sound ... a place that's known for bad vis and strong currents. On the other hand, if you don't believe in it, it's unlikely you waste much time teaching your students how to do it.
In which case, I'd be shooting a bag, tying off the line to the wreck, and ascending up the line.
Thank you for dragging the level of conversation down to name-calling ... I expected better from you. I'm not talking about dogma ... I'm talking about addressing the reason WHY this accident happened.
You either use the buddy system as it's intended to be used, or give it up altogether ... in which case you train, plan, and equip to dive solo. Giving lip service to a buddy system without training people how to do it is pointless.
In my opinion, by not pointing out in the article that a breakdown in buddy diving is what caused this accident, DAN did a huge disservice to its readers.
FWIW - I do occasionally dive solo. When I do, my plan, equipment and mental approach to the dive reflect the decision to do so. However, when I make a decision to dive with someone, my plan, equipment, and mental approach to the dive reflect the fact that I am diving with another person, and that part of the plan includes beginning, executing, and ending the dive together. If you cannot make the commitment and effort to do that, then you should not be diving together.
This conversation has nothing to do with "dogma" ... and I find your choice of words both insulting and, basically, ignorant of the point. It has EVERYTHING to do with dive planning, executing basic skills you are SUPPOSED to be teaching to your Open Water students, and a mental commitment to diving with another individual.
It's not rocket science ... it's not even particularly difficult. You just have to know how to do it, and decide that you want to ...

NWG - The only thing you are forgetting is what I was talking about.
I prepare for every dive that has a buddy as though my job is to watch out for them.
However, if I'm being a good buddy, and they are not, and we get separated, I'm a lot less likely to end my co$tly dive to go find them.
I've had several cases in my limited dive career where the other person puts the fins into high gear or descends like a rock on one of the cranes or holes here in our Quarry and are never seen again.
In the quarry, I know my way around, so I will look for them, and if I call a dive, it's 25$ for the whole day, no biggie.
On the charters I've been on, where it's easily 100+ a day for 2 tanks, I'd be a lot less inclined to call a dive because someone decided they were too bored to swim together and took off.
THAT being said. In caribbean water, I'm finding it hard to believe that with 60-100' of visibility, anyone could ever be truly "separated" and not know it. Even in the quarry with 10' of viz, I have to make a conscious, concerted effort to get away from my buddy. He's either watching me or following me. (This is my personal buddy - not an insta)
I think more and more this whole debate depends more on the two people involved in the buddy system and not the buddy system itself, to be honest.
Like I said earlier.
NOONE is going to risk time or money or personal injury for some complete stranger. If they got on the boat, they knew the risks, and if they can't manage to stick together and use the buddy system, I'm not gonna kill myself to figure out where they got off to.
If it was my best friend - his life is worth the time, money, and risk of injury to save.
Again, like I said, anyone who says they treat an insta-buddy that way is lying.
At the end of the day, the buddy system IS fundamentally and fatally flawed.
It assumes that two living, breathing, thinking people who don't know each other, can go into a situation of life or death emergency and be willing to put their life on the line to save/help the other.
I contend that the average human being is much too selfish for that system to ever work among strangers.
If you aren't diving with someone who you know for a fact will make that level of comittment, you aren't diving with a buddy. You're diving with a possible source of air should you need it and be close enough to it at the time of need.

No one? I know several law enforcement offers who do this every day. In fact, countless numbers of your average citizens have come to the aid of complete strangers at the risk of their own peril. I know some average folks who are the kind of people who would NOT be able to just stand by and do nothing.NOONE is going to risk time or money or personal injury for some complete stranger.
Since I prefer to use the designated "lead" diver system I have to ask what is wrong with that approach? If visibility is low someone has to be the designated navigator don't they? Otherwise you'd never get anywhere unless you both knew exactly where you were going and both had predetermined the route to take to get there. How do you explore someplace new if nobody is leading?
