Diving with enriched nitrogen-oxygen (nitrox) mixtures requires special knowledge of
the variations imposed upon divers, their activities, and their equipment by the in-
creased percentage of oxygen. SEEMANN recommends completion of a specialized
Nitrox training course by a recognized training agency prior to diving with any enriched
nitrogen-oxygen (nitrox) mixtures.
WARNING: In the event that you exceed the maximum limit of per dive
allowable oxygen exposure, it is recommended that you allow a
surface interval of at least 2 hours before reentering the water.
If you
exceed the maximum limit of 24 hour period allowable oxygen expo-
sure, you should allow a surface interval of at least 24 hours.
ALTITUDE DIVING
Diving at high altitude requires special knowledge of the variations imposed upon
divers, their activities, and their equipment by the decrease in atmospheric pressures.
SEEMANN recommends completion of a specialized Altitude training course by a rec-
ognized training agency prior to diving in high altitude lakes or rivers.
Atmospheric pressure decreases as altitude increases above sea level. Weather
systems and ambient temperature also affect barometric pressures. Consequently,
depth reading instruments that do not compensate for the decrease in pressure
indicate depth readings shallower than the depth they are actually at.
The XP 5 automatically compensates for decreased ambient pressure when activated
at high altitudes up to 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 caution.
