learn-scuba:In the better than twelve years I've been diving, I have never had any gear stolen at any time with the possible exception of a dive knife while in Roatan and that could well have simply been lost. Gear laying around on picnic tables at training areas, boats and so on it typical and by-and-large I have found divers to be trustworthy. Perhaps because they respect what it costs to buy that gear... or maybe because I'm an instructor and they look at my stuff and think "that junk's way too worn out to be worth stealing" ~grin~
Seriously though... for example, this past weekend, I had a group of five students at Devil's Den -- as is standard practice we left our gear and such at the picnic tables when diving. We would be gone for an hour at a time and everything was always right where it was left when we returned. I find that to pretty much always be the case.
Ive had my weight belt (still full of pouches) stolen. The first part was my own fault, i left it next to our boats in the yacht club where its parked. By the time i realised and came back it had gone and not handed in to the club (the only building for aobut half a mile).
Although not first hand ive read elsewhere of drysuits and things going missing off tables and benches.
Its not all grim though, many times we'd had divers come up to our boat on the water and ask us have we lost a torch as theyve found one, come into a charter shop and ask the same and someone did return my knife which i hadnt even realised id lost at the time. Like everything else, there are a few bad individuals in a group (in this case divers).
