but I have been a little hesitant to dunk my 300 camera in the water haha
I know what you mean, but look at it this way: if the camera is waterproof, you spent extra money for the same guts just for that feature. Until you start using that feature, you spent money on something that you aren't using.
While dunking electronics is something we instinctively try to avoid, when it comes to waterproof cameras and the results...it only seems wrong the first time.
