Lars: Yeah, maybe it's just me lol (but I'm not about to tell Canon's distributor that; they pulled out my unit, no questions asked beyond my date of purchase). The casing is supposed to be good up to 130 feet although I did notice that a bit of moisture gathered (Is it supposed to do that?) the last two outings, both deep dives. I'll continue to check for upgrades, thanks.
Ace, I do put some tissue on the sides of the camera's face, upon a friend's advise, to supposedly prevent scratches from it being banged away by current. Uh oh. Now I'm thinking, fibers -- not good for the sealing.
Carlos, I did change the memory card from the original one which allowed too few shots for my liking. Hmmm...
Lottie, if only puckering up solved it
