I lost one cell phone while detecting at the edge of the surf at night with an incoming tide. The holster snap came open and the cell dropped out. Lost another cell phone in a hot tub. Just wasn't paying attention to what was in my pocket when I got in. Also lost a silver chain and silver cross. My wife said I shouldn't wear it into the water, and I said, "How can it come off, it is around my neck." A significantly larger wave than normal, caused by a passing ship, just lifted it off my neck and the next 6 waves pushed me away from where I was standing so there was no way to try to find it by feel. This was before I started metal detecting. Dumb, dumb, dumb. She didn't try to make me feel bad about not listening to her, I think she knew I felt bad enough already. She subsequently replaced it with a gold chain and cross, which I do NOT wear to the beach for obvious reasons....lol
