I take instabuddies most of the time, so I try to do a "pretty good" buddy check. I tell him/her about my rig first, which I think makes it easier for buddy to respond re those same items on their rig.
So, for example-- "okay, I have a conventional rig, see it here?, regular octo, conventional buckle weight belt, here's the inflate and deflate. I like to check air at 2000, 1500, 1000, using just the fingers of one hand, here's what my gauge looks like. I carry a knife, shears, light, slate. How about you??" I usually get a similar type of response. Then, "what do we want to do with this dive"--linger over a smaller area, or cover as much ground as air allows? What are you interested in?"
That's about it. Do I think others do it? Hadn't really noticed. But after I do it, I think others who overhear it, start doing their own.
