ReACT Pro
The no decompression algorithm is based upon Haldane’s theory using maximum allowable ni-
trogen levels developed by Merrill Spencer. Repetitive diving control is based upon experiments
designed and conducted by Dr. Ray Rogers and Dr. Michael Powell in 1987. Diving Science and
Technology
®
(DSAT), a corporate affiliate of PADI
®
, commissioned these experiments.
O2 Dive Time Remaining
As oxygen accumulation increases during a nitrox dive, Dive Time Remaining before reaching
the oxygen saturation limit for that dive, or 24 hour period, decreases.
When the O2 time becomes less than the No Deco Dive Time Remaining (NDL), calculations for
the current depth will be controlled by oxygen. Oxygen Time Remaining will then appear as the
main numeric time display as signified by the OTL symbol (Fig. 78a).
ALTITUDE DIVING
Atmospheric pressure decreases as Altitude increases above sea level. Weather systems and am-
bient temperature also affect barometric pressures. Consequently, depth reading instruments that
do not compensate for the decrease in ambient pressure indicate depth readings shallower than
the depth they are actually at.
The ReACT Pro automatically compensates for decreased ambient pressures for Altitudes be-
tween 2,000 (610 meters) and 14,000 feet (4,267 meters). Its program contains a high altitude
algorithm that reduces no decompression and oxygen exposure limits to add a larger zone of cau-
tion.
