True. There are different schools of thought, and that is acceptable. I happen to be a firm advocate / proponent of primary donate. That is how I dive. That is what I teach. But, I also ensure that I discuss with my buddy, BEFORE the dive, how I am configured and how I dive. It is not a matter that should cause contention or consternation.Angelo farina:I am well aware of this theory, but it is not generally accepted everywhere.
Frankly, I don't plan to run out of air on a dive. I intend to be self-reliant. BUT, I do want to understand my buddy's configuration, just as I want my buddy to understand mine, 'just in case'.
I agree with that view. It is a different environment, with different priorities. One of my regular dive buddies is a firefighter. We have discussed this very issue (that they are trained never to give up their gas supply) in detail. It does not represent an obstacle to our diving together. Rather, he pointed it out simply to explain why he has not heretofore been an advocate of primary donate. Notably, through our discussions he has become more interested in the primary donate configuration and process. That doesn't mean he will be changing his behavior as a firefighter.The whole firefighter thing strikes me as a very poor analogy.
I don't see a problem with both approaches being in existence, as long as the divers involved are aware of the differences. An OOA / LOA diver, with their wits about them, will in all likelihood follow their training, as Edward3c points out. And, if it is alternate donate, they will look for the buddy's alternate. If it is primary donate, they will expect to get the primary. A panicked diver - all bets are off. They will in all probability go for whatever they can see. If that happens to be a regulator in another diver's mouth, so be it. If that were to happen to me, and my primary reg is suddenly pulled from my mouth, I have time to put my bungeed alternate in. In fact, the purge cover on my primary is yellow (the cover on my bungeed alternate is black) to make it easier to see (and take, if needed).
