M2 USER MANUAL
When displayed and stopped, the stop
timer can be reset to zero by the press-
and-hold of the -/DOWN button.
4.8.2.3 Setting bookmarks
By a press-and-hold of the “LIGHT” button
you can set any number of bookmarks as
reminders of particular moments during the
dive. The bookmarks will appear on the
dive profile in SCUBAPRO LogTRAK.
4.8.2.4 Safety stop timer
If a minimum depth of 10m/30ft is reached
during the dive, at a depth of 5m/15ft the
safety stop timer will automatically start
a 3-minute countdown. If you go below
6.5m/20ft, the timer will disappear and the
no-stop time will be shown again. Upon
returning to 5m/15ft, the timer will start
again automatically.
4.8.2.5 Activating the backlight
To activate the backlight, press the LIGHT
button. The duration of the backlight is 10
seconds.

NOTE: The backlight is not available
when the BATTERY CHANGE warning
appears.
4.8.2.6 Diving with MB levels
Microbubbles are tiny bubbles that can
build up inside a diver’s body during a dive
and normally dissipate naturally during an
ascent and on the surface after a dive.
Dives within no-stop times or that observe
decompression stops do not prevent the
formation of microbubbles in the venous
blood circulation. The M2 is equipped
with an enhanced SCUBAPRO algorithm,
named ZH-L8 ADT MB, that has been
designed to reduce the formation of these
microbubbles.
This enhanced algorithm allows you to
choose a level of conservatism that exceeds
the worldwide proven safety record of the
standard ZH-L8 ADT algorithm. There are
five levels of additional conservatism (or MB
levels) that have been programmed into the
M2, from L1 to L5, with L5 being the most
conservative and L1 being just a bit more
conservative than the standard ZH-L8 ADT,
here referred to as L0.
Choosing a MB level between L1 and L5
makes the algorithm more conservative;
therefore, you will have either shorter
no-stop times or deeper and longer
decompression stops than when diving at
L0. Consequently, the body will either take
up less nitrogen (shorter no-stop dives) or
will be able to off-gas more before returning
to the surface. Both work towards reducing
the amount of microbubbles present in the
body at the end of the dive.
Please refer to the section

microbubble level
