Diving with microbubble (MB) levels
Decompression obligation
Subgear XP-3H calculates and displays level stops to reduce microbubble formation, but it also
calculates the diver’s decompression data.
WARNING
Avoid decompression dives when diving with MB levels.
How to avoid decompression stops:
• Check ordinary no-stop time by pushing
until L0 appears.
• Observe the nitrogen loading bar (it is relative to L0)
• If the nitrogen loading bar flashes (less than 3 minutes to deco):
ascend slowly a few metres/feet.
WARNING
At the beginning of a decompression phase an attention beep goes off and the
DECO
symbol
flashes for 8 seconds.
In order to prevent a dive with long decompression stops it is recommended that you ascend a
few metres/feet on seeing this message.
If decompression stops become obligatory, the
DECO
symbol
will be displayed. The total ascent time will now also contain a
decompression stop.
Level stop and deco stop
When the level stop depth equals the depth of the fi rst obligatory decompression stop and if you are
within 1.5m /5ft of the stop depth itself, Subgear XP-3H shows
STOP
DECO
and
STOP
(level stop). The indicated
duration refers to level stop duration.
Since level stops are more restrictive than decompression stops, when all decompression obligations
have been observed the display changes from
STOP
DECO
STOP
to
STOP
only.
