Jeff, you are looking at one concept and forgetting all of the rest - please
try to hold the entire package in your head, not separate out different things
while forgetting others. The manifold is independents when the isolator is
shut,
but we do not need multiple regs and guages on each tank. The manifold is a
pinhole and when an o-ring blows it takes days for the gas to get out - also
using the correct manifold makes this very difficult. The bust disks are
plugged, both of them.
Besides haveing two tanks, which is not really necesary (you could use on
big
one), you have two ports to access each of them while keeping a streamlined and
clean gear config that allows sharing and full backup while maintaining that
streamilined and clean profile. The double tanks are way overkill, as we always
come back with most of the gas from any dive unless we had a problem, which is
why we took the extra gas in the fist place. Only a stroke surfaces with less
than 2000 in a set of hundreds from any dive, unelss he , like us, uses the
trimix in teh back tanks for air breaks" from the deco gases for a long period
of time, but at that point the dive is over and the botom gas is no longer life
support.
I think that what we are arguing here is bad configs for bad divers vs good
congfigs and good practices. What most of these guys need is a pair of runing
shoes and a cotton remover. - G
