With each depth display, you will see either 'predicted' no decompression limits
based upon your previous dive profiles (if calculated to be nitrogen controlled),
or 'predicted' oxygen tolerance limits based upon accumulation of oxygen (if
calculated to be oxygen controlled).
No decompression times are only displayed for depths where there is at least 3
minutes of dive time available at the depth, taking into account a descent rate
of 120 feet (36 meters) per minute. Depths greater than the maximum depth
that can be achieved with a partial pressure of oxygen (PO2) of 1.60 ATA will
not be displayed.
Prior to a Repetitive Nitrox Dive
If the segments of the Tissue Loading Bar Graph are displayed (Fig 35) during
the Pre Dive Planning Sequence, that next dive is calculated to be controlled
by nitrogen loading.
If the segments of the O2 bar graph are displayed (Fig. 36), that next dive is
calculated to be controlled by oxygen loading.
The Pro Plus will store oxygen accumulation for up to 10 dives conducted dur-
ing a 24 hour period. In the event that the maximum limit for oxygen loading
has been exceeded for that day, all of the segments of the O2 bar graph will be
displayed (Fig. 37).
