I use a bolt snap attached directly to the rig and snapped off to a D-ring when not in use. However, 95% of the time it's in my hands and not bolted. What if I drop it or it's knocked from my hands? I also use the coiled lanyard. I have a good one that has a bolt snap on either end and I never ever detach it from my rig or my waist D-ring while diving. When I hand my rig to the boat guy I keep it attached until he has a firm grasp and then I detach it from my waist D-ring.
