Guys....we're forgetting THE MOST important reason why I'd rather dive
tables than a computer ..... electronic devices can and will fail
underwater! I believe the question was posed as "What is the difference
between following a deco schedule produced from a set of
(computer-generated) tables, and following a deco schedule produced by a
computer on your wrist?" That's easy....if your 500 MHz Pentium III
running Z Plan fails while calculating your dive information, chances
are, you're not underwater in a life threatening situation.... When (not
IF...but WHEN) your CockRing, or NiTEK (I hate that name!), or any deco
computer fails in the middle of the dive, you're left with either backup
tables and a timer, or pulling deco out your butt....
since electronics do fail underwater, why not just skip that whole step
and rely instead on the computer between your ears and a set of good
tables....?
