How does this diver know which reg to pick up next?
is it possible to have this many tanks on 1 manifold?
Would you even want to do that? Would they be set
up as doubles but each tank on its own regulator?
I see the manifold on the tanks on his back but
can't see the tanks underneath.
Just curiosity mostly.....
eventually I'll have my own doubles but not 5 sets of
doubles at the same time WOW!
(oh and what about pressure gauges, how would you know which one went to which tank??
