I have 2 Velbon tripods with the flat head and a thumb screw sticking up through the flat head to attach my spotter/camera to. Does anybody make a quick disconnect adapter to screw to the flat base of my tripod? I am not overly fumble fingered but I have darned near dropped my Kowa spotter on several occasions while trying to get the screw started into the spotter. Of course I will need the base to attach to the adapter but hopefully this will eliminate the near misses and trauma of dropping a spotter that I cant afford to replace. Or worse, dropping my shooting buddy's Swarovsky, which cost as much as a pretty good used car!
