3. Diving with Galileo
English
3.7.1 Prohibited altitude
Going to altitude, as much as flying after
diving, exposes your body to a reduced
ambient pressure. In a way similar to the
no-fly time, Galileo advises you which
altitude classes are safe to reach after a
dive and which aren’t. If you have to drive
over a mountain pass to return home after
a dive, it can be quite important to have this
information.
The prohibited altitude classes are
displayed by grey segments inside the
stylized mountain. This can be combined
with black segments indicating current
altitude. In the example above, the diver is
presently at altitude class 2 and should not
reach altitudes of class 4.
Galileo has an altitude alarm: If you were to
reach an altitude that according to Galileo
is incompatible with your current residual
nitrogen levels, it will warn you with an
altitude alarm (see section 1.4 for more
information).
3.7.2 Decompression dives
in mountain lakes
In order to assure optimal decompression
even at higher altitudes, the 3m/10ft
decompression stage is divided into a
4m/13ft stage and a 2m/7ft stage in
altitude ranges 1, 2 and 3.
If atmospheric pressure is below 610mbar
(altitude higher than 4,000m/13,300ft), no
decompression calculation is carried out
by Galileo (automatic gauge mode). In
addition, the dive planner is not available in
this altitude class.
3.8 Gauge mode
When Galileo is set to gauge mode, it will
only monitor depth, time, tank pressure,
and temperature, and will not carry out
any decompression calculation. Maximum
displayed dive time in gauge mode is
99 hours and 59 minutes. You can only
switch to gauge mode if the computer is
completely desaturated. All audible and
visual alarms, other than the low battery
alarm, are turned off.
!
WARNING
Dives in gauge mode are performed at your
own risk. After a dive in gauge mode you must
wait at least 48 hours before diving using a
decompression computer.
When on the surface in gauge mode,
Galileo will show neither the remaining
desaturation time nor the CNS O
2
% value.
It will however display a surface interval up
to 24 hours and a 48 hour no-fly time. This
no-fly time is also the time during which you
cannot switch back to computer mode.
The surface display changes as shown
below:
During a dive in gauge mode, the following
information is displayed:
- current depth
