Subject: Re: Helium
Very nice post.  It's refreshing to read a question or point on this
list that is
put in such a well thought out way.  Such detail is necessary in order
to avoid
the almost instant flames that come from most questions.  On to my
thoughts...

I am not trimix certified.  I did, however, spend the best diving time
of my life
with the WKPP.  I spent almost every weekend with them in Tallahassee
for over a
year and can honestly say that they really do have their act together.
The
training that I received from more experienced team members would not be
possible
to duplicate in a trimix certification course.  I feel, no, I KNOW that
I am a
much better trained trimix diver than most who complete a certification
course,
regardless of the fact that they have a c-card and I do not.

Can you honestly say that in a 4 day course you can pass on more
information and
training about helium than I received in my 'year long course'?  We, as
humans,
are always learning and when we surround ourselves with the right kind
of people
on a regular basis we are much more likely to really learn and
fundamentally
understand  than we are when faced with a classroom environment.  Doing,
doing
right, and doing regularly are far more important than paying money to
take a
class and get a card.

I think the most important lesson that I learned while on the team was
to know
when to just shut up and listen (took me a while, but I get it now).
When there
are people that know so much about certain topics that are willing to
share this
information and teach you, free of charge, you really just need to
listen and
take it all in.  It's the best education you can possibly receive, but
no card is
involved.
