DANGER: The use of nitrox should not be undertaken
without proper training. Nitrox dives will expose the diver
to different risks than those of air dives, including serious
physical damage and, in extreme cases, even death.

DANGER: As a safety measure the Archimedes II
computer utilizes a PO2 limit set at 1.4 bar even for air
dives. Should you require an additional safely margin, it is
possible to set PO2 at lower values, down to 1.0 bar, by
decrements of 0.1 bar.
WARNING: After a dive with the Archimedes II set in Gage
mode (depth meter-timer). The instrument will not make
saturation and de-saturation computations during the
remaining 48 hours elapsing from the depth meter’s use.
WARNING: Avoid diving activities that result in unsafe
profiles such as "yo-yo" dives, dives with reversed profiles
or several subsequent dives during subsequent days.
Diving activities such as these are potentially dangerous
and present a higher risk of decompression sickness.
WARNING: Please utilize the most conservative safety
factor at all times. By doing so, you will dive more conser-
vatively, which will minimize the likelihood of decompres-
sion sickness.
NOTE: While flying, the Archimedes II should be stored in
the pressurized cabin.
NOTE: Cressi-sub strongly recommends that all sport
diving activities be conducted within the guidelines of no-
decompression diving and at a maximum depth of 132 ft.
Exceeding these perimeters dramatically increases the
likelihood of decompression sickness
As a result of technological advancements/changes, Cressi-
sub reserves the right to modify the Archimedes
II computer
without notification.
1.3. – Introduction.
The Archimedes II computer is a multifunctional instrument
for sport diving. It will supply information on depth, dive times,
decompression status, ascent rate, and surfaces interval
time between dives. Nitrogen absorption and release is con-
tinuously processed by it’s sophisticated software.
Information is displayed in large characters on the
Archimedes
II ’s User Friendly Display System (UFD). This
system allows for easy and direct dialogue between the diver
and the computer, ensuring a clear understanding of all the
data needed at any given time.
Additionally, the computer is equipped with a watch and
calendar, a multifunctional dive memory (logbook), and a dive
simulator.
The Archimedes II ’s mathematical model can make satura-
tion and de-saturation computations of dives carried out with
air, and with up to two different nitrox mixtures. These may be
selected during the dive itself. Nitrox mixture(s) dives may be
set from the maximum PO2 value between 1.0 and 1.6 bar to
oxygen percentage (FOG): the primary (MIXI) between 21% -
50% for O2, the second (MIX2) between 21%-99%.
Additionally, the computer may be set by the user for either
metric (m -°C) or feet (ft. -°F).
Archimedes II Cressi-sub underwater computer may be
connected to a compatible PC, by means of a Cressi-sub
