Subject: Re: Rebreathers

(In reply to your message dated Wednesday 2, August 1995)

Rich et al
                  Many of the problems associated with the subject of 
rebreathers of any
type is due to ill-informed opinion by so-called 5 minute experts. Much in the
same vein as the much discussed IT card thread. That really is not a problem 
providing the people concerned accept that they grasp only the theory and
nothing else. The practicalaties are a different beast entirely. 

I, to a lesser extent than Rich cannot divulge any specific design information 
on the Cis L. rig. I agreeed not to and have been fortunate enough to have
dived the
rig a few times. For what it's worth my own feeling is that the potential has
not
been realised yet - seriously!. However, right know I would not make a serious
dive on anything other than OC. Mainly due to not having what I feel is
anywhere near
enough 'cockpit' time.

The frightening thing in this whole issue is back to the old discipline
routine. First time
out everything is hyper-aware - absence of noise,the odd click,auto diluent
inject etc.
Time moves on, more dives more relaxing. Confidence in the automatic systems
grows.
Constant monitoring becomes occasional............right?

WRONG.   Rebreather diving requires more discipline than most would give credit
to. If
you thought the progress to trimix diving was involved think again.

I suppose the whole world waits with baited breath for the first readily
available C2. Will
it be the Cis L mk 5?. Who knows - not even Cis L. Will it be an 'off the
shelf' unit' that can
be purchased on production of a C card?. Absolutely not the training will be no
less thourough
than it has been for the people that dive the mk 4 at the moment. I guess that
the whole
thing is similar to the way that mix diving has gone. There are people who
would have you 
believe that it is for all. It is not. It is an avenue to follow and it takes a
lot of work - shortcuts
have only one outcome.
