WARNING!
THE USER SHOULD BE AWARE THAT ANY DIVE, INCLUDING ONES WITHIN THE U.S. NAVY TABLES OR DIVE
COMPUTER LIMITS, DOES CARRY SOME RISK OF DECOMPRESSION SICKNESS.
COMPARTMENTS AND HALF TIMES
When you dive with the instrument, it measures and displays depths and times as your dive progresses. It shows you available
no-decompression time and possible decompression required based upon the following five factors:
1. your present depth,
2. excess nitrogen absorbed during earlier portions of the dive,
3. residual nitrogen remaining from previous dives,
4. the no-decompression limits that apply to that depth,
5. the personal/altitude adjustment mode in use.
Back on the surface, the dive computer will continue to calculate the no-decompression dive times available for various depths
on the next dive. As the surface interval increases, so does the available dive time for the next dive.
To perform these calculations, the dive computer continuously models the absorption and release of excess nitrogen from
theoretical compartments. Each compartment absorbs and releases nitrogen at a different rate. The compartments that absorb
and release nitrogen rapidly are believed to have a high tolerance for excess nitrogen, whereas compartments that absorb and
release nitrogen more slowly are believed to be more sensitive.
