Why do you dive with a buddy if you know that neither of you will provide life sustaining help if needed?
Because we were going in the same direction on the same wreck. It doesn't mean we were buddies in the same sense as it would have been on a simple shallow reef dive. This is where people are not getting it. Andy explained it quite well. Maybe it's not sinking in due to the indoctrination and nannying that Andy is talking about. Even with advanced recreational dives the emphasis is on buddy skills and practices where despite the depth you still have a DIRECT ascent to the surface option.
Again, these are not the type of dives John said were involved. Some also seem to have missed where he said that if it were a training situation and he was the instructor that he would render whatever assistance was necessary. And though it wasn't stated I'm betting that after the incident he would inform the student that on an actual dive it is quite likely that would not have happened.
When my GF and are in the water together it is understood that I will do anything to help her. I'd give up my own gas for her. But we are not doing dives where to do so would pretty much insure I will die. In fact I would not be doing those types of dives with her. Unless she had the same level of training and experience and mindset that I do regarding mortality and diving. As far as diving goes I know she does not. And has no plans to persue that route. On the latter subject we agree with each other wholeheartedly. And know what to expect for and from the other.
When I teach an AOW class the emphasis as I've already stated is heavy on buddy skills to the point of I will fail a student in a heartbeat or stop the class until we get an issue worked out if they show a lack of (talking to) or disregard for(fail) proper procedures. The skills in the advanced class I offer are about the same as my Intro to Tech class. With the exception of the use of doubles and a few other gear mods. Where it also differs is in the idea of buddy skills and self reliance. The skills are still there. But there is more emphasis on independence and not RELYING on the ability of the buddy to change the outcome of a problem.
When we did Steve Lewis's (Doppler) disaster scenario there were eight what I would consider experienced and accomplished divers in the water in close proximity. Various scenarios were run through. Switching the reg on a hung bottle to simluate a failure, entanglement, etc. But the focus was on how to get yourself out of the situations. Not how to get your buddies attention to do it for you. It's nice if a buddy can help. But on tech dives of the nature John was writing about that option fast goes away.
The WKPP/DIR approach works for those types of dives and does so because that is what they train for and plan for. The people who dive the Doria and other deep wrecks, solo cave divers, solo wreck divers, etc. don't use that approach. I have said before that any dive I will do with a buddy I will do solo. I will not do every dive I will do solo with a buddy. There are times when it simply is more effective and less risky to do the dive alone and not have to be in any way responsible for someone else. But it is stated up front that the situation is such.
I guess you have to have gone through tech training with someone who understands this to appreciate the difference. And to have dived with those who follow these ideas. It's all comraderie and smiles and laughing on the surface. We'd stick out a hand to keep a guy from falling on the boat and if we happened to get an injury from that it would not be held against the guy. But under the water it is a different story.
An accident there should have been foreseen. An equipment failure planned for as well as a way to deal with. By the diver himself or herself. If it wasn't they should not have been doing that dive. And this is where the Intro to Tech and subsequent tech classes differ from recreational training. In recreational training you might see 2 or 3 pages in the manual about all the fun and excitement you will enjoy. In tech classes it will soon be noted that here is how you might die before anything if the class is rooted in reality.
As to the danger of new divers reading and misinterpreting the article and getting hurt. I suppose that is possible. Grown men have been known to look at a red hot weld and ask "is that hot?" as they actually touch it! Some call it curiosity. Realists see it for what it is. Stupidity. And a
sense that someone will somehow protect them if it truly is dangerous.
That they do not have to be responsible for themselves.
I truly believe that this is also a factor in some diver deaths where a buddy was present but untrained in rescue skills. They were operating on the false belief that someone else would protect them and the other diver. Because they were led to believe that in their early training when the instructor said "oh, you don't need to worry about that yet" or "the DM will handle that" or "you're too new to handle rescue skills" that used to be taught in every OW class until it was realized there was a more profitable way to pass those skills on later.
And this is where the "everybody can dive" mentality comes back to bite people. We often talk about the physical conditions that indicate a person is unsuited for this activity. We rarely or never talk about the mental and psychological conditions that should also be a clear indication that a person should not be in the water. "I can't swim but I think I should still be able to dive", "I don't need to learn all that stuff you teach, just give me the bare minmums I need to survive cause my plane leaves next week", and other such indications that the judgment of the person is seriously compromised. Yet some will take these people and give them a c card and lament the poor skills, reef bouncing, zoom off and leave an insta buddy attitude they have. When it could have been avoided by simply telling them they are not suited for this.
New divers have to understand that there are aspects of this that will kill you at every level. But it's taboo to say that. Must not negatively affect the bottom line. And this is why people might try it. Because they have been lied to and led to believe that it can't happen -death,injury- to them. That it's so rare that while we acknowledge it can happen we minimize and avoid a serious detailed discussion. If we confronted the fact head on and were open about it from the beginning of the Open Water Class I believe some would still be alive.
