RE:   "A Stroke’s Progress".

Andrew,

It would appear that your knowledge in these matters is somewhere in
between your armchair and an aquarium based on the  probative nature of
your questions regarding the safety advantages of an isolation
manifold.  Despite the fact that the obvious reasons for using an
isolation  manifold have been beat to death on cavers and techdiver
allow me to clarify several points for you.

The Hogarthian gear configuration, while simultaneously simplifying and
streamlining you and making your diving a safer and more pleasurable
experience is but an underlying component of the WKPP’s system of "doing
it right".  This system integrates an Hogarthian gear configuration with
teamwork, adherence to procedures, attention to detail and a exacting
physical and mental commitment to diving.

The isolation valve enhances the safety of a manifolded system which
itself provides you and your dive partners with access to all of your
gas, should the need arise. You cannot effectively share gas with a dual
independent system.  Dual independents are the epitome of the worst type
of personal preference and total violation of the "doing it right
credo". Under the "doing it right"  way of thinking your buddies life is
always put ahead of your own.  If you believe this you not only will you
never dive with dual independents (unless you are sidemounting in which
case the subject becomes irrelevant), but you will never even consider
getting in the water with someone who subscribes to this archaic and
dangerous practice. 

Two of the fatalities which have befallen members of the USDCT in recent
years involved the use of dual independent convoluted gear.  The most
recent horrifying example of this form of "beyond the pale" gear idiocy
occurred in Blue Hole #4 in the Bahamas last week. The use of this type
of foolish gear configuration certainly contributed to the fatality.
Crisis management during a "charlie foxtrot" is difficult under ordinary
circumstances; however, with dual independent gear it is almost
impossible.

If you subscribe to the "my air is my air" and every man for himself ,
solo diving philosophy practiced and taught by certain individuals in
the training community then forget everything I just wrote.

Go and do some diving and see for yourself. 

Regards,

Bill
