SAFETY STOP
GOA/CARTESIO is programmed to automatically recommend a safety stop after
any dive to a depth of 10 m or more, as recommended by diving theory and the
latest studies on diving physiology. A safety stop should last 3 minutes and should
be made in a depth range of between 5m (16ft.) and 3m (9ft.).
The safety stop is shown on the display with the SAFE icon. In this condition the
display clearly shows the stop time in minutes and seconds with a countdown.
While it is not mandatory, the safety stop is strongly recommended, for instance,
when the maximum ascent rate is exceeded repeatedly. Cressi recommends ma-
king the safety stop on a regular basis so as to avoid safety problems.
NOTE: During a safety stop, the maximum depth can be seen by pressing
the UP .
ASCENT RATE
Ascent rate is shown on the display by a dot indicator situated in the centre of
the display, which works according to the table shown in the gure below. If the
maximum ascent rate values are exceeded, the display will show the indication
SLOW and three ashing icons, while an audible alarm is also given out. In these
conditions, you have to stop the ascent until the indication SLOW disappears and
the display returns to normal conditions.
NOTE: If the maximum ascent rate of 12m/min - 40ft/min is exceeded for
a prolonged period of time, the GOA/CARTESIO watch-computer makes the
following dive more conservative, but only if it is done during the desat period
of time, so as to protect the diver from the risk for DCS. The
!
icon tells
you that the penalization factor is active.
DANGER: An exceedingly fast ascent rate causes the risk for DCS to increase
exponentially! Cressi recommends to make a safety stop, of 3 minutes at a
depth of 5m (16 ft.), which will be computer assisted at the end of each dive
(see the next chapter).
