Thalassamania:What we really need to know is how many tanks were filled each year, that would give us a rather good, though abstrated, value for diving effort each year.
How do we sort out which were used by divers, and which were used to refill paint ball guns??
They have some cool 38 cal, 45 cal, and 50 cal pellet guns that you refill with a scuba tank that can down a deer!! Look up quackenbush air guns.
