28
Desat Time is not displayed after a Gauge or Violation dive.
Desaturation requiring times greater than 24 hours will display 24 (or 23:50)*. until the
time decreases to the maximum the display will allow depending on the configuration of
the model PDC being used.
Generally, the Desat countdown will reach 0:00 prior to the Fly countdown reaching 0:00.
In the event that Desat Time still remains at the end of 24 hours, when Time to Fly becomes
0:00, the unit will shut off and any remaining Desat time will be cleared.
*We do not go beyond 24 hours since there is not a realistic set of repetitive dive profiles on
SCUBA for which the 480 minute tissue exceeds 8 FSW, which clears at 24 hours. All other tis-
sues with a half time of 160 minutes or less will have desaturated in less than 12 hours.
