GoPro is waterproof. From what I gathered on another thread like this, the Contour is not. You have to buy a case to make it completely waterproof. $30 or so for the case. I dont think you can go wrong with either one! Norbi (www.vimeo.com/norbiv
) shoots some of his videos with a contour, and Ryan Taylor (ryantaylorvisual.com) shoots some GoPro videos, if you're looking for examples of what each one's product looks like.
