Back to the original question- When is it ok to leave your buddy? In my book, and for all those I train, the answer is never, unless the buddy is trapped and you have no alternative but to leave and get assistance. My wife is my dive buddy if she is on the boat, and we have hundreds of dives together. If I am not diving with her, and have an assigned buddy, I always have a mini-briefing with my buddy beyond the dive boat briefing. In casual but pleasant conversation I learn their name, when they last dove, their experience level, whether they have any issues (problems equalizing, air consumption, etc.) and share the same with them. Too many people, especially on dive boat excursions led by a dive pro in the water omit this step and assume they will all just be together. They attach no meaning to having a buddy, and have no communication with them to speak of before the dive. That is bad. ALWAYS do a buddy plan- and if you are the new diver, like the OP, it is all the more important, for you and for your buddy. If a buddy has an ear problem, stay with them, even surface with them to be sure they are ok, and then proceed if you are up to it. A new diver may not want to go rejoin the group. The DM in the water should have had an awareness of the issue, but the new diver is still responsible for herself and her buddy. If a diver is feeling anxiety about the dive they sure better share it with the dive leader AND their buddy. So, everyone, be a buddy. Plan the dive with your buddy, get acquainted with you buddy before the dive, and be sure you have an understanding of what you will BOTH do in different circumstances. That's diving 101. Learn it and remember it and practice it. I have blog on this if you want a little more info. Divers are friendly peope- let's talk to each other before every dive.
