I keep a 3 1/2" rubber gasket around my wrist and bolt snap lights, cameras, compass, etc to it depending on my needs. I bought like 100 of them from McMaster Carr years ago and keep a few in my boat bag just in case. I've been known to recycle my wife's stretched out hair bands, too.
A diver's life all about the bolt-snaps. No small number of us here might even say we have a problem with collecting bolt snaps.
Piranha is currently making the "upgraded style" of bolt-snaps at a much more reasonable price than the XDeeps.
