I agree with whoever said he puts his rig together the night before and doesn't let anybody talk to him. That's what I do.
That would be me. It looks like a huge percentage of these incidents are caused by rushing and not paying attention. It doesn't suprise me though. It's pretty easy to get complacent. I recently did a Great Lakes dive to over 100' in poor viz and realised I didn't look at my gauges for the first 15-20 minutes of the dive. And we're talking life support here - not a stupid camera. We/I just get a bit too comfortable and stop paying attention.
It sounds like most of these situations are pretty obvious.
So far no one has mentioned things like a cat hair across an o-ring...
Funny, I had to clean about three or four cat hairs off the main seal o-ring's on the first few days of the trip to Bonaire I just returned from. I know they're from my curious tabby because they have this agouti ticking (banding) pattern. However, the cat hairs were long, stiff and straight, so it was easy to see and pick them off - it's the much thinner wrinkly cotton fibers that seem to stick against the o-ring that scare the heck out of me when I find them wrinkled up on the o-ring...
Note to self - be sure to adopt cats in colors inversely related to my current rig's o-ring colors. Black cats and black o-rings = bad luck!
