WARNING
Even when performing a PDI stop, you still
MUST perform a safety stop at 5m/15ft for 3 to
5 minutes. Performing a 3 to 5 minute stop at
5m/15ft at the end of any dive is still the best
thing you can do for yourself!
2.4 Digital compass
Galileo has a tilt-compensated digital
compass which can be used at almost
any inclination. The compass can be called
up at any moment during the dive and it
can also be used on the surface. This
menu allows you to use the compass on
the surface, change the auto-off time and
assign a declination to compensate for the
deviation between true North and magnetic
North.
2.4.1 Using the compass on the
surface
Upon selecting the USE COMPASS
menu, the screen will display the compass,
the time of day and the surface interval, if
applicable. The buttons are now labeled
“
SET ” and “ EXIT ”.
With the middle button (“ SET ”), you can
set a reference bearing. This is useful for
instance if you are on a boat and there is a
landmark on the shore that you can use for
alignment to reach a specific spot on that
dive site.
Press “ SET ” to set the bearing,
and the display shows the message SET
BEARING SUCCESSFUL for 2 seconds.
A dot will appear to indicate the set bearing.
Once underwater, align the dot with the
arrow and start swimming in that direction.
If you
press “ SET ” again, the new bearing
will override the one in memory. If you
press and hold “ SET ” you erase the
bearing. When you set a bearing, Galileo
automatically marks the points at 90, 120
and 180 degrees as an aid in navigation.
See section 3.4.1 for more information on
using this feature.
The right button (“
EXIT ”) returns to the
main Digital compass menu.
