GALILEO 2 TEK (G2TEK) USER MANUAL
• Against long exposure and repetitive
dives.
Repetitive diving and very long
exposures (technical and rebreather
diving) with high ppO
2
may cause long-
term pulmonary Toxicity effects that can
be tracked with OTUs. See chapter:
OTU
settings
how you can check your current
OTU information or reset the counter. If you
exceed your OTU’s for the dive, this will be
noted in the logbook alarms/warnings as
shown on the screen below.

Technical diving
You should be trained and properly
certified by a recognized agency in
technical diving before using G2TEK for
that. Decompression diving, diving with
high oxygen percentage blends, multi gas
diving and mixed gas diving all require skills
and demand know-how that only specific
training and education can provide. A dive
computer is an electronic instrument that
cannot make decisions for you and can
not take all parameters into account while
diving.
In technical diving a dive computer is not
the primary instrument to follow during the
dive. Before the dive you must make a plan
and during the dive follow it. If your plan and
the computer show different schedules,
follow the more conservative one.
WARNING
Both G2TEK Trimix model and trimix diving are
developed for healthy, physically fit, advanced
divers. You should have regular medical check-
ups with a specialized physician, confirming
your physical aptitude for diving. This is even
more important for technical diving.
Patience is a very important characteristic to
maintain when conducting complex dives. It is
necessary to build your personal depth limit
and decompression amount based on your
real diving experience and then increase little
by little as you gain experience.
G2TEK is not designed for commercial diving.
Special procedures such as surface supplied
gas, heated suit, decompressing in a chamber
or bell and long, high workload dives may
cause algorithm to calculate incorrectly or
even disturb the operation of the G2TEK dive
computer.
Never dive without a backup instrument.
It is imperative to always have backup
instruments for depth, time and tank
pressure, as well as a dive table with you
while diving.
Plan your dives in advance and cross check
your plan with another commercial planner
program or table. Your dive plan should always
include reserve gas amounts sufficient to
handle emergencies and/or delays. Always
make bailout tables for the dive.
Technical diving is not for everyone.
Decompression diving, especially with Helium
mixes, will always have a higher inherent
potential for an accident, which could lead
to permanent injury and death. The risk may
be higher due to differences in an individual’s
physical condition, environmental conditions,
human errors, etc. If you are not willing to take
the risk, don’t dive!
