Using
A Dive Computer
5.
Make your deepest dive first and plan
successive dives to progressively shallower
depths. During a dive, start at the
deepest point and work your way shallower.
As recommended by the dive medical community,
avoid going from shallow to deep. Computers
will continue to give you no decompression
times if you break this guideline not
because it's okay, but because it's
better than no data at all. Avoid making
multiple deep dives with short surface
intervals between them.
6.
Stay well within computer limits. Always
try to have five or more minutes no
decompression time remaining. If you
let it near or reach zero, you've pushed
the limits even though you'll have plenty
of no stop time when you ascend to a
shallower depth.
7.
If your computer quits, you may need
to stop diving for 12 to 24 hours. If
it quits during a dive and you've been
staying well within the no decompression
limits, ascend immediately to 5 metres/17
feet, make a safety stop for five minutes
or more and surface. You can't simply
grab another computer because it won't
know how much residual nitrogen you
haw. Follow the manufacturer's instructions.
8.
Take the RDP for backup on dive trips
so you can resume diving the next day
if your computer fails. If you computer
fails and you've been tracking your
depths and times. and your dives stay
within RDP limits, you can continue
diving using the RDP. Otherwise, you'll
probably have to wait until the next
day for residual nitrogen to clear before
you resume diving. Although it's computers
you dive resort to have dive computers
you cant rent, don't count on it. Take
your RDP so you can be sure you won't
miss out. Preferably, take The Wheel
so you can plan multilevel dives that
maximize your no stop time.
9.
Keep thinking. Dive computers can fail
just like any other piece of' equipment.
Don't blindly accept everything your
computer says, especially when it appears
way out of line with a buddy's computer
or your previous experience. Read the
manufacturer's instructions completely
before using your computer, and follow
what they say. You can learn more about
the theory and use of dive computers
in the PADI Multilevel Diver course.
