FREE DIVE MODE DETAILS
• Although breathing apparatus is not utilized for free dive activities, nitrogen tissue loading remains a factor. Nitrogen loading is calculated based
upon a fixed FO

of Air.
• Since a user has the option of alternating between SCUBA and free dive activities within a 24 hour period, nitrogen calculations and the displayed
value of No Decompression Dive Time Remaining are carried over from one operating mode to the other, which permits the user to maintain
awareness of nitrogen absorption and off-gassing status.
• The mathematical models currently used in the GEO AIR 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 (Dive, Gauge, 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 decom-
pression 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.
