6.6 RBT when diving with more
than one gas mixture
Galileo determines the RBT based on
your breathing pattern. The tanks with
the various gas mixtures you have with
you may be of different sizes, therefore
the RBT calculation cannot be extended
to all tanks at once since your breathing
pattern will be different for each tank. Since
Galileo performs several decompression
calculations simultaneously for all possible
combinations of gas mixtures, the RBT
calculation references the decompression
calculation that considers only the gas you
are currently breathing from.
- If you have programmed 2 or 3 gases
and are currently breathing from T1,
the RBT will be for the decompression
schedule that considers T1 only.
- If you have programmed 3 gases and
are currently breathing from T2, the RBT
will be for the decompression schedule
that considers T2 only.
- If you are breathing from TD, the RBT is
for the decompression calculation that
is actually displayed on the computer
screen.

Gauge mode and gas switching

By pressing and holding the left button,
you manually start the gas switch process.
The only result of switching gas mixtures
in gauge mode is that the pressure of the
newly chosen tank is displayed instead of
the current one. There are no restrictions
on when a gas switch can take place in
gauge mode. The message SWITCH TO
GaS T2 (or TD or T, whichever is next in
sequence) appears on the display, and the
button labels change to SaVe (left) and >>
(middle). Press or press and hold the left
button (SaVe) to confirm the switch. Press
or press and hold the middle button (>>)
to move to the next tank in the sequence.
Press and hold the right button to interrupt
the gas switch procedure without carrying
out any switch. If the switch is completed,
the message SWITCH TO GaS T2 (or TD)
SUCCeSSFUl appears on the display for
4 seconds.

6.8 Logbook for dives with more
than one gas mixture
For dives carried out with more than one gas
mixture, Galileo adds a page in the logbook
for each gas mixture. These appear just
before the page listing warnings and alarms.
Each page shows oxygen concentration,
starting pressure, end pressure, consumed
pressure and, for T2 and TD only, depth at
which the switch took place.
6.9 Planning dives with more than
one gas mixture
The dive planner considers all programmed
gas mixtures when computing no-stop
times or decompression schedules. When
more than one gas is set, the symbols T1,
T2 (if applicable) and TD appear on the dive
planner screen.
