Having done my OW and most of my dives in New England, I was excited to do my DMT course in tropical waters. I don't see how people need a wetsuit in 31C water. Thus, I was all excited to go in with a t shirt and board shorts, you can jump into the water with the same clothes you arrived to the dock in, no contortions needed to get into a wet suit, no exposing your beer belly or your pale buttocks to the Dutch coeds! In my excitement, I forgot to check my pockets and took my iPhone 3G to 10 meters. Though, I did find an ingenious tech who managed to fix it (new screen, new battery, new power controller)... though same tech has decided to steal the phone and not give it back... Thailand...
