ALADIN H USER MANUAL
The Aladin H features 6 microbubble
levels (L0-L5). Level L0 corresponds to
SCUBAPRO’s well-known decompression
model ZH-L16 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, the Aladin H 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 you will be required to perform a stop
(level stop) sooner than a diver using level
L0.
If you ignore a required level stop, the Aladin
H will simply step down to a lower MB level.
In other words, if you choose level L4 prior
to the dive, and during the dive you ignore
the L4’s recommended stops, the Aladin H
will automatically adjust the setting to level
L3 or lower.
3.8.1 Comparison of dives with MB
level L0 and MB level L5
When two Aladin H dive computers are
used simultaneously, with one unit set to a
MB level of L5 and the other to a MB level
of L0, the no-stop time for the L5 unit will
be shortened and more level stops will be
required before the diver has the obligation
of a decompression stop. These additional
level stops help dissipate microbubbles.
