Hi Duane,

I think it's time for you to get a reality check.

You may be right (although I don't personally agree) that << ... the
biggest 
problem I

have with computers is that reliance on computers promotes a diving

population with no knowledge of decompression theory and how it applies to

what they're doing... >>  But do you know what?  The vast majority of divers 
(and that means virtually the entire diving population except the extremely 
small technical and commercial portion) don't give a hoot about deco theory 
and never will.  They just want to go down 60 ft., look at pretty fish and 
take pictures on their once a year trip to Cozumel.  Tell me again the story 
of why my grandmother needs to know how an internal combustion engine works 
so she can drive the car to the supermarket.

Also, you need to realize that advances in technology (like computers and 
other such things) may be extremely beneficial.  For you to say << ...
So, 
instead of knowledge, we have reliance on gadgetry, and most of the diving po
pulation appears to gravitate towards replacing knowledge and technique with 
gadgets and shortcuts... >>  If you really believed this, then I would expect 
to see you diving with a horsecollar (or no BC at all), double hose 
regulator, large oval single lens mask and a J-valve (because you didn't 
trust SPGs and after all you should have been keeping track of your gas usage 
constantly.)  Starting to get the idea?

Why don't we start talking about technical diving?  After all, isn't that 
what this list is all about?  And keep away from thinking that the whole 
world cares a whit about what we think or do.  Nitrox computers are here to 
stay for sport diving and I for one think they are extremely helpful in this 
area.  If you'd like to debate this premise, I'll be glad to do so.  But you 
are heading for a big loss.

Take care and dive safe,       Scott

Some weeks it's just not worth the effort to gnaw through the restraints and 
scramble up out of the pit.

YES.  Computers think bouncing is OK, the conservatism is fixed, half use

Haldanean bullshit algorithms, they don't support correct profiles, most

recommend ascent rates that are too fast, etc., etc. All the same reasons

they aren't OK for bigger dives, as recently discussed, still apply.


But, In addition to all their technical shortcomings, the biggest problem I

have with computers is that reliance on computers promotes a diving

population with no knowledge of decompression theory and how it applies to

what they're doing.  So, instead of knowledge, we have reliance on gadgetry,

and most of the diving population appears to gravitate towards replacing

knowledge and technique with gadgets and shortcuts. This is the mentality

that gets people bent and killed.


There was a time when I was less Draconian in my acceptance of some rec

diving practices, but my tolerance for idiocy among any aspect of the diving

population has been steadily declining since my first body recovery.
