Not by itself. All those cameras come with a plastic enclosure, tho, and when used correctly the camera can be used underwater no problem. Not sure how deep it can go- I've only taken it down 4 feet at most. When I'm done I wash the (still enclosed) camera off with fresh water to get any sand/salt/crud off, then dry and open the enclosure. Sometimes there's a bit of sand in the gaskets, easily brushed off.
