Buddy check for 12 foot lumpsucker dive:
Got your hood? Got your mask? Check primary in the water (eliminates folded diaphragms and catches subtle freeflowing) Check backup. Wing inflate/deflate/dump valve? Drysuit inflate/dump valve open? Gauges? Weights? Cutting implement? Pocket contents? Fins? Takes about as long to do as it does to read

(With non-DIR buddies, I'll also ask about releases and how somebody's weight is configured. I'll make sure I know where all their dump valves are and how they are operated -- you'd be amazed at how many people don't even KNOW where all their options for venting their BC are! --and I'll have a quick look at their inflator, so I know how IT works. I got stuck once with a buddy with severe buoyancy issues, and his inflator had little colored PLATES on it instead of buttons. I had no idea which did what, and some of them seemed to do nothing.)
Dive plan for 12 foot lumpsucker dive: Goals -- to look for lumpsuckers! Course described. Team: Bob leading, me and Kathy flanking him. Special equipment? Bob's camera. Exposure? 20 feet max, time around an hour or until somebody got cold. Deco? Irrelevant. Gas? Who has what, where we head home. Environment? Shallow, silty, sometimes unpredictable current.
Again, took about as much time to run through as to read. And when we got in the water, everybody knew where we were going, how we were going there, how long we were going to be there and what parameter would determine that, and what to expect from the dive. We also knew everything was working and nobody had forgotten anything or had any issues.
Contrast that with the dive I did at the same site, where I did a ten minute surface swim to discover I couldn't descend because I had forgotten my weight belt -- we had all geared up in different cars, and hadn't run through a team check before getting in the water. It was a long swim and a long walk back to get it.
It's not hard to do! And it saves a bunch of inconvenience.
