 WARNING
Before diving, make sure you have
correctly set the units of measurement. An
incorrect setting may give rise to confusion
during the dive, and hence to underwater
behavior errors.
 WARNING
Do not dive in mountain lakes without
having first checked that the appropriate
altitude program is selected and without
special training for altitude diving.
 WARNING
In order to use your Puck Air safely, Mares
suggests, in addition to the dive computer,
also using a depth gauge, a submersible
pressure gauge, a timer or watch, and dive
tables.
 WARNING
When diving in poor visibility conditions,
the indications provided by the computer
may not be visible.
The safety of a dive can only be increased
through adequate preparation and training.
Mares therefore recommends using the
dive computer only after having completed
a specialist diver training course. Mares
recommends scrupulous adherence to the
simple rules of the behaviour listed below:
RESPONSIBLE DIVING PRACTICES
• Always plan your dives in advance.
• Never exceed the limits of your skill and
experience.
• Go to your deepest planned depth at
the beginning of the dive.
• Check your computer frequently during
the dive.
• Comply with the ascent rate indicated by
the computer.
• Always do a safety stop between -6 and -3 m
(-20 and -10 ft) for at least 3 minutes.
• After any decompression-stops, ascend very
slowly to the surface.
• Avoid yo-yo dives (repeatedly ascending and
descending underwater).
• Avoid strenuous activity during the dive and
for half an hour after surfacing.
• When diving in cold water or after an
intense exertion, start ascending well before
reaching the no-decompression limits.
• In the case of a decompression dive, prolong
the decompression-stop nearest the surface
for safety.
• Repetitive dives should be separated by a
surface interval of at least 2 hours.
• Your deepest dive should be the first one of
the day.
• Avoid diving until the computer memory has
cleared from the preceding day’s dive.
• When doing repetitive dives for several
consecutive days, take at least one day off
from diving every week.
• In the case of decompression-stop diving,
it is recommended to take one day off from
diving every three days.
• Avoid decompression-stop dives and do not
dive deeper than 40 m (130 ft) unless you
have been specifically trained in this type of
technical diving.
• Avoid repetitive “square profile” dives (dives to
a single depth) deeper than 18 m (60 ft).
• Always wait at least 12 hours, and preferably
24 hours, after a dive before flying, in
accordance with the recommendations of
the Divers Alert Network (DAN).
FLYING AFTER DIVES
Mares Dive Computers have the follow
recomendations:
• Single no-decompression dive: a minimum
no-fly time of 12 hours is suggested
• Single dives with decompression-stops:
a minimum no-fly time of 24 hours is
suggested
• Repetitive dives: a minimum no-fly time of
24 hours is suggested
