ADDITIONAL INfORMATION PERTAINING TO fREE DIVE MODE
Although breathing apparatus is not utilized for fREE Dive activities, nitrogen tissue loading remains a factor. Nitrogen loading is
calculated based upon a fixed fO2 of AIR.
Since a user has the option of alternating between NORM (SCUBA) and fREE Dive activities within a 24 hour period, nitrogen calculations
and the displayed value of No Deco Dive Time Remaining (NDC Time) are carried over from one operating mode to the other, which
permits the user to maintain awareness of nitrogen absorption and offgasing status.
The mathematical models currently used in the A300 CS are based on no decompression/decompression multilevel repetitive dive
schedules.
These algorithms do not take into account the physiological changes associated with the high pressures that competitive type free diving
can expose a diver to.
WARNINGS
Ensure that you know which Operating Mode is selected (NORM, GAUG, or fREE) prior to commencing any dive.
Conducting free dives within a 24 hour period after conducting SCUBA dives, combined with the effects of multiple
rapid free Dive ascents, increases your risk of decompression sickness. Such activities may result in accelerated entry
into decompression which could cause serious injury or death.
Combining competitive type free dive activities that involve multiple descents/ascents with activities utilizing SCUBA
during the same 24 hour period is not recommended. Presently, there is no data relating to such activities.
It is highly recommended that anyone planning to become involved in competitive type free dive activities obtain
proper instruction and training from a recognized free Diving trainer. It is imperative that the physiological affects be
understood and the diver is physically prepared.
