The gas summary table is visible both on
the surface and during the dive. On the
surface it allows you to review your settings
and, if the transmitters for all tanks are in
range and have not turned themselves off
to preserve battery life, it allows you to
verify the pressure in each tank. To bring
up the table, press and hold the middle
button (marked lOG) from the time of day
display. Pressing the middle button once
the table is displayed brings you into the
picture-viewing function.
During the dive, the gas summary table is
useful to remind you at what depth you
planned to perform the gas switch(es) and
also to verify again the pressure in each
tank (provided that the transmitters are in
range and are active). To bring up the table,
press and hold the middle button (marked
MORe). The gas summary table stays on
the display for a maximum of 12 seconds,
after which Galileo reverts to the regular
computer display. Pressing the middle
button while the gas summary table is
displayed brings up the DeCO SUMMaRY
TaBle, explained in the next section.

Deco summary table
Galileo shows you the predictive multi-
gas decompression calculation on the
main computer screen. However, in the
background it is also calculating what the
decompression would be if you were to
finish the dive with just the gas mixture
that you are currently breathing from. If you
are diving with an MB level higher than L0,
Galileo also computes both the predictive
multi-gas decompression calculation and
the current gas only calculation for L0. All
these calculations are shown at once in the
DeCO SUMMaRY TaBle.
During the dive, from the gas summary
table, press the middle button to access
the deco summary table. On the top row,
with label PMG l5 (or whichever MB level
is active) you see the predictive multi-gas
decompression calculation at the active
MB level. This is the same as on the main
computer screen. Underneath it, with label
G l5 (or whichever MB level is active) you
see the decompression calculation for the
active MB level if you were to finish the
dive with the gas mixture you are currently
breathing. Next is the row with label
PMG l0, showing the predictive multi-gas
decompression calculation for L0 (this is
what you see in the MORe sequence also),
followed by row G l0, showing the single
gas decompression calculation at L0 for
the gas you are currently breathing from.
The first two rows described here do not
appear if Galileo is set to L0.
The deco summary table stays on the
display for a maximum of 12 seconds,
after which Galileo reverts to the regular
computer display. Pressing the middle
button while the deco summary table is
displayed brings up the dive profile. In the
case of dives with more than one mixture,
Galileo adds a solid line indicating the MOD
for the various gas mixtures. The vertical
line then represents the predicted time and
depth of the switch.
