I'm still trying to find a setup using the prototypes you sent that work for me. In a cave, having the gopro on the webbing straps *much better with 2" webbing now btw* is a bit better, but it still isn't still enough compared to hands or helmet. The light mount isn't bad but is more useful for working dives when you actually need both hands free. At that point, they're on a helmet. For cave diving the system actually is working better for strapping the gopro to the body of the scooter, same with the light mount I have, but on the body I haven't found a way that works, especially considering recreational divers that have trim all over the place, you might be looking where their body is looking, but not where the head is looking.
