Subject: Re: Divers Supply Press Release
Jeff,

I am not in the area any longer, am not a member of WKPP and in now way
involved with this matter.  With that said a few questions remain.  

First and foremost what is your relationship with Divers Supply and the
charter operator.  Just because you compiled this report (or had a hand in
compiling it) does not mean it should be taken as gospel.  

Second, the survivor's comments in this matter are to be viewed as HIGHLY
suspect as he may or may not have something to hide.  This "Official Press
Release" is just that, a press release.  Calling an opinion or observation
a "fact" does not make it a fact.  Had others on site witnessed the events
and survived their observations may have been very different and
contradicted the statements of  Mr. Roth.

Third why was this dive conducted without some form of redundant /
inadequate flotation.  In the "Official Press Release" you and / or others
state that steel 72s or 80s were used.  My experiences from Broward Co.
Florida tells me that a diver using dual lp steel  95s and two lp steel 72s
as stage bottles is grossly over weighted when diving wet!!!  Who is
responsible for this???  My trimix instructor would never have allowed that
situation to exist without redundant flotation!!!  Other gear concerns
aside, why was so much "travel gas" and deco gas needed for the dive plan
outlined?

Just as a FYI:  If I were planing the dive I would not use a travel gas.
Bottom gas of 16/50 trimix from surface to bottom and back to 130', switch
to EAN32, then to 30' and switch to EAN84.  With .5min deep stops on bottom
mix at 210' and 170' then 1min stops from 130' through 50', 5min @40',
6min @ 30',  9min @ 20', and 20min @ 10'.  Total deco 50min, total run time
including deep stops and travel 76min.  I have done this type of profile
with NO problem (in fact I feel better after this profile then after the
longer profile in your post).  

Forth from the information you presented this class was being conducted out
of standards.  A 17% mix at 250' gives a 1.47PpO2. for the bottom mix.  If
memory serves me IANTD limits PpO2 for bottom gas to 1.40 ata.  Therefore,
the dive was NOT "in compliance with IANTD (International Association
Nitrox and Technical Divers) standards".  And the "facts" presented in the
"press release" are FALSE!!!  The gas choice for this profile is suspect at
best.  

What we know for fact from this incident (note: I don't call it an
accident.  That is yet to be determined.) is that:

1) Three divers are dead
2) Buoyancy problems due to lack of redundancy IS a contributing factor
3) Poor choices with respect to tank selection MAY have added to the
buoyancy problems.
4) The true "FACTS" may never be known

From what IS known the instructor was responsible for this incident by not
following the standards of IANTD and the "diving community".  A few key
elements of the "Official Press Release" make this painfully clear!!!  I'm
sure that I am not the only one on this list smart enough to figure this
out.  I can't wait to how you explain this away to those waiting in the
wings to tear into this.  At any rate good luck you are going to need it
after this admission of guilt!!!
