A&D 2 Plus owner manual Introduction

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	Figure 1
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.
