As the title says, I'm thinking of buying a new GoPro to use on a helmet after trying a cheapo camera and getting crap results, especially the sound. Now because they are expensive I am concerned about BBs hitting the front and damaging the lens cover and LCD front display. Most skeleton covers don't protect either and I don't think the mobile type screen protectors will be up to the job. So, is the only choice the fully enclosed divers case or are there other options as the sound will probably be blocked, I had to mod the case on the cheapo camera to allow sound recording.
