NOTE:
The following chapter deals with
the characteristics of diving with
microbubble (MB) levels. For general
information
features of diving with Aladin 2G see
chapter 3.
Microbubbles are tiny bubbles that can
build up inside a diver's body during any
dive and normally dissipate naturally during
an ascent and on the surface after a dive.
Dives within no-stop time and observance
of decompression stops do not prevent the
formation of microbubbles in the venous
blood circulation.
Dangerous microbubbles
migrating into the arterial circulation. The
reasons for the migration from the venous
blood circulation to the arterial circulation
can be a great many microbubbles
collecting in the lungs. SCUBAPRO has
equipped Aladin 2G
with a new technology to protect from
microbubbles.
The diver chooses – according to his/her
needs – an MB level and influences through
it the level of protection from microbubbles.
Diving with MB levels requires additional
ascent stops (level stops), the ascent is
slowed down and the body gets more
time to desaturate. This works contrary
to the formation of the microbubbles and
increases safety.
Aladin 2G features
levels (L0-L5). Level L0 corresponds to
SCUBAPRO's well-known decompression
model ZH-L8 ADT and does not require
level stops due to microbubble formation.
Levels L1 to L5 offer additional protection
from microbubble formation with level L5
offering the highest protection.
Similar to the display of information during
decompression dives or dives within no-
stop time, Aladin 2G displays depth and
duration of the first level stop as well as the
total time of ascent as soon as the MB no-
stop time has run out. As the MB no-stop

time is shorter than the ordinary no-stop
time a diver will be required to carry out a
stop (level stop) sooner than a diver using
level L0.
If a diver ignores a required level stop,
Aladin 2G will cascade to a lower MB level
and the dive can not be completed with the
initially chosen MB level. E.g. if a diver sets
level L4 on Aladin 2G prior to the dive and
during the dive ignores the recommended
stops Aladin 2G will automatically adjust
the setting to level L3 or lower.
