Just a comment about the buddy checks. I teach all my students how to do it and they do it before every dive from Pool Dive #2. In the class I go over it and how long it can take. When you know how to do it, it can go real quick. Real quick.
I was timed by my DM at the pool last week, using an unfamiliar BC (I had only used it maybe twice by then and was still learning it) and my Buddy Check, covering all bases, showing my buddies (the students) everything they need to know about my equipment that they need to know, in order to save my life, if something goes wrong...(geez, it took me longer to write that than to do the check) took 18 seconds!
If your buddy can't spare 18 seconds to make sure you stay safe and that he stays safe, well, then, you need a new buddy.
