That said, unfortunately in the effort to get the camera/housing out of the fray you've introduced two additional thumbscrews to mix. Not sure if it's a net win or loss. I would replace at least two of the thumb screws with machine screws. You certainly don't need all of those to be adjustable.
Also, if you collide with someone in freefall or faceplant on landing you could turn a bruise/headache into a gash as polycarbonate is pretty hard and the Gath doesn't offer much to stop it.
Great tip about the screws. Thanks.
The classic Gath has some protection in the zone where the camera is placed, it's a little bit thin, but I think it's good enough....., or maybe not? ¬¬
BTW, Thanks for the answer :)
