        Oh, please!  The entire reason for computer diving is to have an
instrument that will allow you to extend your bottom time by not forcing you
to use your floor depth as the depth of the entire dive.  Please explain to
me, short of doing an amazing amount on mathematical calculations, how one
does a wall dive that starts at 100' and goes to, say, 60' for a total time
of an hour?  Try to plan that on your tables, then compare that deco time
with what a computer would say.  If I recall right, "normal" (i.e.
non-decompression specific) tables don't even allow a 100' for 60 min.
situation.
        In short, there are reasons to carry a computer.  There are also
reasons to carry two computers.  There is NO reason to buy a computer and
still use your tables!  This is worthless!
