I can find em but im wondering which are best for impact shots.Some guys have cameras on there bows but the shot makes it all wobbley and then it usually goes to the ground as the shooter lowers his bow.Im trying to make a video that films what im looking at,Any suggestions.

I just came across this camera made for dirt bike riders to film while they ride. I haven't seen it in person yet but my brother inlaw says it works well.
