DIVE TIME REMAINING (DTR)
One of the most important pieces of information on AERIS dive computers is the 'Dive Time Re-
maining (DTR) display'. The dive computer constantly monitors no decompression status.
No Deco Dive Time Remaining (DTR)
No Deco Dive Time Remaining (DTR) is the maximum amount of time that you can stay at your
present depth before entering a decompression situation. It is calculated based on the amount of
nitrogen absorbed by hypothetical tissue compartments. The rates each of these compartments ab-
sorb and release nitrogen is mathematically modeled and compared against a maximum allowable
nitrogen level. Whichever one is closest to this maximum level is the controlling compartment for
that depth. Its resulting value will be displayed numerically (Fig. 9a) along with the No Decom-
pression Dive icon and graphically as the Nitrogen Bar Graph (Fig. 9b).
As you ascend from depth following a dive that has approached the
no decompression limit, the Nitrogen Bar Graph will recede as
control shifts to slower compartments. This is a feature of the de-
compression model that is the basis for multilevel diving, one of
the most important advantages that AERIS dive computers offer.
The no decompression algorithm is based upon Haldanes theory
using maximum allowable nitrogen levels developed by Merrill
Spencer. Repetitive diving control is based upon experiments de-
signed and conducted by Dr. Ray Rogers and Dr. Michael Powell
in 1987. Diving Science and Technology

(DSAT), a corporate af-
filiate of PADI
