Thanks for the input Kav. Yes I've used it in swimming pools probably about a douzen times only. I did choose to use this over other cameras when I was trying to make some pictures during inclemant weather (snow storms, rain). It's a little tank for sure, and the first thing that surprised me about the camera was how good the 35mm lens was for above water photography. As Kav suggests, I would certainly change the o-rings for diving to anything approaching 160 feet. Actually, as I have not used it in years, I would change the o-rings regardless, although they do look just fine. By the way, B&H has a used one at 278.95!
