Thanks guys, I am using the solid waterproof case but I had to drill a hole in the side so I could plug the jack of the mic into the camera. Works great. I am messing around with mic placement now. I put it under the left side cover and the sound is even better. I deleted the footage though because I got sea sick watching the video it bounced around so much. I will retake some footage and post the results.
Feel free to discuss any GoPro items in my thread hear I love the discussion.
