Diving with enriched nitrogen-oxygen (nitrox) mixtures requires special knowledge of the variations
imposed upon divers, their activities, and their equipment by the increased percentage of oxygen.
AERIS 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 allow-
able 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 exposure, you should allow a surface in-
terval of at least 24 hours before reentering the water.
ALTITUDE DIVING
Diving at high Altitude requires special knowledge of the variations imposed upon divers, their ac-
tivities, and their equipment by the decrease in atmospheric pressures. AERIS recommends comple-
tion of a specialized Altitude training course by a recognized 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 ambient pressure indicate depth readings shallower than the depth
they are actually at.
The ATMOS
ai
automatically compensates for decreased ambient pressures for Altitudes between
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 caution.
