I'd like to ask a silly question in this thread.

From my personal experience, even the 3x zoom can give me blurred
pictures from my boat. I can only assume 10x would be worse.

Unless you are paddling in a super-wide boat in very calm conditions.
In which case I don't see the need for waterproof. Granted you could
be taking photos in the rain, but I doubt it.

So what is the advantage of a 10x zoom waterproof digital camera? I
have to assume I am missing something.
