So I'm planning on running my GoPro on my AR tomorrow and was wondering who has done this. If you have, the real question I have is which case to use? I have 4 choices. 1) Closed front case w/ closed back case (used wen wanting it to be water proof) 2) Closed front case w/ open back case (means sound came come in the back of the camera) 3) Open front case w/ closed back case (sound comes in more from the front) 4) Open front case w/ open back case (most sound that camera can record) I haven't used my GoPro with my AR yet so I don't know whats better. Just wasn't sure if the closed everything is too quiet or the open cases is too loud. Anyone have any input?
