While i'm not a fan of responses like, "Take the course", "Ask your instructor" or "do a search" , sometimes a more complete answer just points out just how complicated the answer could be.
Mike (merxlin) did a great job of demonstrating this in his post.
A word of caution however, do not take lightly the warnings of just how complicated some rescue situations can be. The adage of better one dead than two is no joke and it is a serious concern. Again, see Mike's response.

I think you missed the point. The idea to take a rescue class is spot on. Without getting into the various agencies and the training standards, it is invaluable as both a buddy rescue and self rescue tool.
It is also almost impossible to be "qualified" based on reading a post. Will you have more knowledge than someone who did not read the information? Of course. But do you know what it feels like when you inflate someones BC, start them up, then have the buoyancy change in both your and their BC? Do you know how to respond? You may know how you are supposed to respond but until you try it, you may not be able to execute it.
So in order to answer the question, here are some for you: What will your reaction be upon finding such a diver? What do you think will happen to your SAC rate while you are doing so? Will you remember to check your gages and make sure you have enough gas to do a controlled ascent? How do you manage your BC and theirs? What if they are OOA and you can't inflate their BC? What do you do with them once you get them up to the surface? If and when do you drop their weights? Do you know how to do a rescue tow? How far from help are you? Can you perform rescue breaths once you get them to the surface? Do you need to remove their gear? What will you do if they regain consciousness on the way up and panic?
Granted, if you find an unconscious diver they will be better on the surface than underwater. But getting them their is just one aspect of what needs to be done. So the short answer is " use a controlled and safe ascent". Shooting them to the surface will probably do more harm than good. The best answer is learn how to do that safely for both you and them. There's nothing elitist about that. You are better off crossing your arms and doing nothing than doing more harm to you and/or the other diver.
