Thanks Frank. I hate to say it, but I think it very unlikely that my computer will be found. Yes, Micheal, it was a ****** watch/velcro strap and I know better. It actually works (worked!) perfectly with my dry suit, but I was diving wet and I apparently didn't get it on tightly enough. There was someone in the water who watched me backroll and saw the computer come free, but didn't get my attention. I didn't realize it was gone until I got on the wreck (I monintored my other gauge on the way down). There was a pretty good current, so even though we were tied in close to the crow's nest, the computer drifted quite a bit in the current before sinking off the wreck in the sand (most likely). The computer was a yellow DR NiTek with a blue band.
