Thanks Bud,
I got to be honest I cant say enough about the cam, I love it- easy to work with and takes fantastic picts
The housing with cam inside has a positive bouyancy, but not much (kinda like an iceberg in calm water) if you took a thrashing and lost the cam and it went deep it could take at least minute to surface it probably wouldnt just pop up. So you would probably not find it--remember its made more for scuba so having a cam that floated too much would be a pain in the ass i figure.
As for fitting in the baggy's pocket I think its a no go. No sharp edges the whole casing is rounded, but personally i believe it is a little too big to fit in your pocket. It might look a little gay but it would totally fit inside a small belly pack worn backwards allowing you to paddle and surf. That way you could surf but when you wanted to take a shot the cam would be there for you.
I am posting a picture so you can get a real life idea of how big the housing is: the dimensions are 5"L x 3"H x 3.5" front to back. The front to back would be 2" but since the cam has zoom that extends out it made the front stick out.
Hope the picture gives you a better idea of the actual size.
