Introduction
3
Multilevel diving is where the
Monitor 3 Air excels. By
continuously calculating the
nitrogen absorption/release
of all the compartments, the
computer updates the
amount of no-decompression
time (NDT) you have left. As
you ascend to shallower
depths, the computer credits
you with more allowable
NDT; if you go deeper, it
reduces the NDT available.
DIVING RESPONSIBLY
Years of research and thousands of dives have gone into the
mathematical formulas used by the Monitor 3 Air. However,
the computer does not have special sensors attached to
your body; it doesn’t know if you are tired, dehydrated,
overweight, or out of shape. For this reason, U.S. Divers
recommends that you never push the no-decompression
limits of the computer. Always leave a comfortable safety
margin in respect to no-decompression time, air time and
ascent speed. Let the computer assist you in making your
dive plan. Do not let it control your dive.
WARNING: Using the Monitor 3 Air will not prevent
the possibility of decompression sickness, but using
it sensibly reduces this risk. Any sport diver,
however, must accept that there is no device or
procedure which will totally prevent the possibility
of a decompression accident.
