DataPlus

KNOWING WHEN TO FLY

Due to the present lack of a complete data set derived from actual human

testing, there are different recommendations cited by various scientific organiza-

tions for the amount of time a diver should wait before flying after diving. The

DataPlus follows one of the more conservative of these, cited by Divers Alert

Network (DAN); that divers wait at least 12 hours before flying in pressurized

commercial aircraft, and at least 24, or more, hours if your profiles included

repetitive multi-day or decompression dives. More about flying after diving and

DAN's guidelines is presented on page 76 in the Reference section.

The DataPlus tracks how much surface time has elapsed since you surfaced from

your latest dive. The Time to Fly Mode begins a 24 hour countdown that

starts 10 seconds after a dive (Fig. 18). During the first 12 hours, the countdown

appears for several seconds after the Surface Mode during the Surface Sequence.

During the second 12 hours of the countdown, only the word 'FLY' and the

counter will be displayed (Fig. 19). During this second period, depressing the

control button will reactivate the DataPlus, replacing the Time to Fly countdown

with the Surface Display and scrolling Surface Sequence.

WARNING: Battery removal and replacement will clear the Time

to Fly countdown.
