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 NOR (SCUBA) and FRE Dive activities within a 24 hour period, nitrogen calcula-

tions 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 model currently used in the CompuMask is based on no decompression/decompres-

sion multilevel repetitive dive schedules.  This algorithm does 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 (Nor, GAU, or FrE) 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.
