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 OC1 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.
