HANDLING THE EXTREMES
DATAMAX PRO MAXIMUM DEPTH
The maximum depth the DataMax Pro will display is 249 feet. If you
exceed that depth, the Depth, Max Depth, and Dive Log readouts will display
“ ” signifying that you descended out-of-range (Fig. 24a). For that dive,
you will not see a numeric depth display over 249 feet or a Max Depth indica-
tion other than the double dashes.
Although the DataMax Pro will withstand the pressures found at 249
feet, the depth that you can still use all its features is much shallower.
Before going further, read this warning:
WARNING: The maximum recommended sport diving limit is
130 feet. Any deeper dive should be avoided. Special training
and equipment are necessary for this type of diving. Oceanic
does not advocate diving to depths below 130 feet, or decom-
pression diving.
On a first “clean” dive, the DataMax Pro will allow 7 minutes at 160 feet.
A clean dive is one where there is no residual nitrogen from previous dives.
The DataMax Pro will continue to calculate residual nitrogen for up to 24
hours although the dive counter resets to zero after 12 hours. Depending on
your descent rate, 7 minutes at 160 feet can be a very short amount of time.
