Took out a GoPro cam for the first time at Eldora and was impressed. Pretty harsh environment and it performed well. Went down hard a couple of times and never popped off. The wide angle distorts a bit making the steeps flatter etc but gets in a big picture with is more than worth the trade off in distortion. Sound record quality is hampered by the waterproof case but the sounds can take a back seat to the video. Smaller and lighter than my waterproof digital still cam, I’m sure I will be bringing this along on many missions…
