M2 USER MANUAL
4.8.2.7 PDI stops
The M2 is equipped with the innovative
Profile Dependent Intermediate Stops which
is also available on other SCUBAPRO dive
computers.
The PDI Stop optimizes the leading
compartment off-gassing with a low
gradient at depth which is calculated from
the current profile.
After the dive profile has reached a level
where a PDI Stop is recommended, the M2
shows the PDIS symbol and depth on the
bottom row.
If no decompression is required when
ascending to a PDI Stop depth, the PDIS
symbol and depth start blinking on the
bottom row and a 2-minute countdown
starts.
Once the PDIS depth has been reached,
you should stay in the zone that is +0.5m..-
3.0m/+2ft..-10ft from the shown PDIS
depth. If you descend below this zone the
PDIS counter is deactivated and the M2
calculates a new PDIS depth.
If decompression is required this information
remains on the bottom row. In such a
case the PDIS counter is not shown, only
the PDIS symbol and depth are blinking
on the top row for the 2 minutes that are
recommended for staying in the PDIS zone.
WARNING
Even when performing a PDI Stop, you still
MUST perform a safety stop at 5m/15ft for 3 to
5 minutes. Performing a 3 to 5 minute stop at
5m/15ft at the end of any dive is still the best
thing you can do for your safety.
4.8.3 No-dive warning after a dive
If the M2 detects a situation of increased
risk (due to the potential microbubble
accumulation from previous dives or a CNS
O
2
level above 40%), the NO-DIVE symbol
will appear on the display to advise you
against performing another dive right away.
The suggested time interval that you should
wait prior to diving again is shown on the
Dive mode display.
You should not perform a dive as long
as the no-dive warning is displayed on
the computer screen. If the warning is
prompted by microbubble accumulation
(as opposed to CNS O
2
over 40%) and
you dive anyway, you will have shorter no-
stop times or longer decompression times.
Moreover, the duration of the microbubble
warning at the end of the dive can increase
considerably.
4.8.4 SOS
If you stay above a depth of 0.8m/3ft for
more than 3 minutes without observing
a prescribed decompression stop, the
M2 will switch into
SOS mode. Once in
