maximum allowable nitrogen 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 and
now uses the findings in the Recreational Dive Planner ™ distributed by PADI.
One advantage of using the DataMax Sport is its ability to model many
tissue compartments simultaneously. It constantly updates No decompres-
sion Time as the controlling tissue changes with different depths. You always
have a current prediction of remaining no-decompression time regardless of
which compartment is in control.
ALTITUDE DIVING
The mathematical model in the DataMax Sport accounts for the reduced
no-decompression time available at higher elevations based on NOAA (Na-
tional Oceanic and Atmospheric Administration) guidelines. When diving in
high altitude lakes or rivers (from 4,000 to 14,000 feet), the DataMax Sport
will automatically adjust to these conditions providing corrected depth and
reduced no-decompression times. Over 4,000 feet, depth calibration auto-
matically changes to read in feet of freshwater rather than feet of seawater.
WARNING - Until it has shut itself off, you must not use the
DataMax Sport at a different altitude than the altitude where it was
originally activated. Doing so will result in an error equal to the
difference in barometric pressure, and possibly a false dive mode.
