GALILEO 2 (G2) USER MANUAL
3 .10 .4 Diving with PDIS
F
NOTE: To use the PDIS feature, you
must enable PDIS (see chapter:
PDIS
.).
When the calculated PDI stop is deeper
than 8m/25ft, the G2 shows it on the display
(middle-left window) and continues to do so
until you reach the displayed depth during
an ascent. The displayed value changes
during the dive as the G2 tracks the uptake
of nitrogen in the 16 compartments and
updates the PDIS depth accordingly to
reflect the optimum at all times.
The PDIS depth is shown in the middle
window. During a no-stop dive, as soon as
you reach that depth during an ascent, a
2-minute countdown will appear. You can
have one of 3 situations:
1. You have spent 2 minutes within
3m/10ft above the indicated depth. The
countdown timer disappears and the
alternate information window shows OK
as an indication that PDIS is performed.
2. You have descended more than
0.5m/2ft below the PDIS. The
countdown timer disappears and will
reappear again, starting at 2 minutes,
the next time you ascend to the PDIS
depth.
3. You have ascended more than 3m/10ft
above the PDIS. The PDIS value and
countdown timer disappear and the
alternate information window shows
NO as an indication that PDIS is not
performed.

NOTE: The G2 issues no warnings
relating to a missed PDI stop.
When diving with MB levels, PDIS follows
the same rules as described above. MB
levels, however, introduce stops earlier
and deeper than the L0 base algorithm. As
such, the PDIS display may be delayed and
for certain dives it may not be displayed at
all. This, for example, would be the case for
a shallow dive with air (21% oxygen) and a
MB level L5.
