Diver
On the first dive of the day (when the cambands are dry) I've gotten into the habit of unthreading the outside loop (only) of the cambuckle. I give it a tug and then lift up on the buckle enough to hold tension while I rethread the loop. Then using the extra band length for leverage, I close the buckle. Since I started doing that, I've never had a camband come loose (it's a plastic cam buckle, no problems). I also have a lower band with a scubapro type buckle. I don't worry about getting it extra snug (it stays snug enough) as it's really there to keep the tank from twisitng and loosening the top band. YMMV
