3.3.9
Entering decompression
The HUD will activate a warning shortly
before the first mandatory decompression
stop appears. (Decompression stops will
differ depending on the MB level setting.
See chapter: Diving with MB levels)
This alerts the diver to the fact that a direct
ascent to the surface is no longer possible.
This warning applies to dives with the HUD
set to L0-L5.
Decompression information. When the
HUD calculates the need for a mandatory
decompression stop, it shows you how
deep your deepest stop is (lower left side
of the screen, showing an arrow alongside
3 meters in red). Also, it gives you the total
ascent time (3 minutes, shown on the lower
right).
F
NOTE: After a total ascent time of 200
minutes, the display will show "---" .
A summary of all deco stops required for a
dive can be found on the HUD's Deco table
screen. For more information, see chapter:
3.2.5. Deco table.
When diving with an MB level higher than
L0 and faced with a potential deco stop, if
you ascend for 3 min more than 0.5m / 2ft
above the deepest required MB level stop,
the HUD reduces your MB level to the next
possible level. When no tank is paired, the
lite display will show the new active MB
level (in red under the current gas).

WARNING
Violating
a
mandatory
obligation may result in serious injury or death.
If, when faced with a decompression
situation, you ignore a required deco stop,
the HUD will show SOS at the surface and
will store this information in the logbook.

Diving with MB levels
Microbubbles (MB) 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 conducted within no-stop times and
the 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 because of a build-up
of microbubbles collecting in the lungs.
SCUBAPRO has equipped the HUD with
technology to help protect divers from
these microbubbles.
With the HUD you can choose – according
to your specific needs – an MB level that
will provide a level of protection from
microbubbles. Diving with MB levels
includes additional ascent stops which
slow the ascent process, giving the body
more time to desaturate. This works
contrary to the formation of microbubbles
and may increase safety.
The HUD features 6 microbubble levels (L0-
L5). Level L0 corresponds to SCUBAPRO's
