Free Dive Mode Details - Aqua Lung i300 Owner's Manual

FREE DIVE MODE DETAILS

• Although breathing apparatus is not utilized for free dive activities, nitrogen tissue loading remains a factor. Nitro-
gen loading is calculated based upon a fixed FO
• Since a user has the option of alternating between SCUBA and free dive activities within a 24 hour period, nitro-
gen calculations and the displayed value of No Deco 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 i300 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.
• 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 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.
