DIVE
TABLE AND DIVE KOMPUTER
A
dive computer offers both advantages
and disadvantages (which is yet another
reason for havin, both a computer and
the RDP) :
Advantages:
. They're easier to use than tables
because the track time and depth automatically,
avoiding some human error. But you can't
turn your brain off just because you
turn your dive computer on.
.
They give more no stop time on multilevel
profile,. As you ascend. Yon take Up
nitrogen more slowly and dive computers
credit you for this by increasing your
no decompression time. Tables must assume
you spend the whole dive at the deepest
depth you reach, so your allowable dive
time is much shorter. The increased
no stop time from a multilevel profile
is substantial and the primary benefit
of diving with computers. (Note: The
Wheel let, you plan multilevel profiles
with more dive time, making it the best
table backup for your dive computer;
it offers more no decompression time
than any other table.)
.
They track your more no-stop tine by
eliminating the rounding and coarse
fit that You have with a dive table.
.
They track your the oretical nitrogen
throughout the entire dive day (or longer).
With tables, you have to calculate different
allowable no stop times for each dive,
which vary depending on the first dive
time and depth, how long you're out
of the water, and how deep the next
dive will be. This isn't hard, but dive
computers it automatically
Disadvantages
. They can fail. This can happen before
a dive, during a dive or after a dive.
. They will "let you do them that,
aren't recommended while happily crunching
and displaying the theoretical numbers.
(This is why you can't turn your brain
off.) While they eliminate some human
errors, they create the opportunity
for other.
. You gain dive time by eliminating
hounding. but you give up the extra
conservatism that the rounding provides.
Don't
let these disadvantages dissuade you
from using dive computers - their advantages
are overwhelming, and today ifs more
unusual to a see diver with motif one
than with one. Rather he aware of these
problem; in Section Five, you'll learn
how to avoid them.
