Rich,

I trust all 3 of you are well and you are still getting some sleap at home
(as well as on your deco stops)<g>.

I must remind you of a time not many years ago when to dive relying on
a decompression computer was akin to committing suicide.  Nowadays the
technology is much more stable and I do rely on a pair of computers for
the few air-only dives that I now do.

With the inevitable progress of technology, I expect my children's
children to learn to dive using rebreathers and to wonder with amazement
how we could be so casual in our approach to safety on even fairly shallow
300ft dives that we only carry say 20 minutes spare bottom mix rather than
3 or more hours and also that we are only really capable of surviving one
major system failure rather than 2 or 3.

The point I am making is that, with time, relyablility and opperational ease
will nearer approximate perfection.
