Subject: whats wrong with bondage wings?
 this is something i had posted on aol and thouht i might get the info if i
was looking for here,if my theory on the output press of the inflator hose is
true why wouldnt bondage wings be 'safe' ,primarly i dive single hp120 w/30ft
pony,but im thinking about doubles in the future,thanks. 

 lets think about how the 1st stage supplys air to the second stage,im not
sure if this is correct but here it goes,on a balanced reg,doesnt the 1st
stage supply air to the 2nd stage at approx.140 psi.above the pressure that is
being put on the diaphram by the water surrounding it? if so wouldnt this
thought work,if the intermediate press of 140psi.is enough to inflate the
bladder at the surface with 14.7psi against the reg.,why wouldnt it
be enough to inflate it at 99' . if the 1st stage ups the intermediate of
140psi.to 198.8psi.(due to the water pressure against the diaphram)and the
wings see the pressure increase also
you should still have a 140 psi supply to the wings,right?
