FREEDIVING MANUAL
Congratulations on your purchase of a SEAC diving computer.
The SEAC Apnea dive computer is a technologically advanced device designed
and manufactured to provide all the information that every diver needs.
Periodically check www.seacsub.com for any updates to this manual.
GENERAL WARNINGS
• WARNING!
Read the user manual fully before using the SEAC computer.
Using the computer incorrectly will void the warranty and can
permanently damage the computer.
• WARNING!
Only use the dive computer after you have read all sections of the
instruction manual and you have understood how it works.
• WARNING!
The dive computer is not a substitute for diver training and should only be
used by divers who have been properly trained and who have earned the
appropriate license issued by a Certified Teaching Association.
• WARNING!
Freediving entails risks of syncope, taravana, pulmonary edema, and
hemoptysis, and in general other risks related to diving: even a thorough
reading of this manual and use of the instrument does not exclude
potential dangers.
• WARNING!
The computer cannot take into account individual physiological changes
that can change from one day to the next. For this reason it's good
practice to use the device conservatively and cautiously, remaining within
the limits shown by the computer in order to minimize the risks.

• WARNING!
It is strictly forbidden to freedive in the 12 hours after diving with scuba
equipment!
Violating this rule could considerably increase the risk of decompression
sickness.
• WARNING!
No fly time after a freediving session
Because no in-depth hyperbaric studies are available that are suicient to
evaluate the safety of flying for freedivers, in order to avoid decompression
sickness following deep freedives, it is recommended that you wait 18 to
24 hours before boarding a plane, depending on the total dive time, the
number of dives, and the average depth of the session.
Even for sessions with depths of less than 15-20 mt/50-65 ft and a limited
number of dives, a pre-flight interval of at least 12 hours is recommended.
You should stay consistently up-to-date on DAN updates and instructions.
• WARNING!
Do not share one computer between two divers during the dive. Every
diver must have their own instrument to provide information and save
only that diver's data.
• WARNING!
Before diving, you must check the battery charge. Do NOT dive if the low
battery icon is visible on the display. Always check that the display shows
no signs of any malfunction and that it is clearly legible.
The Battery icon on the display has 2 segments:
Segment 1: Battery Outline ==> Battery lower than Minimum Voltage (do
not dive).
Segment 2: First Bar from the bottom ==> Battery lower than 2.1V (Low
level. The voltage could plummet during a dive in especially cold water).

• WARNING!
Always check that the settings are correct for your dive, and don't allow
anyone else to tamper with your computer before the dive. If it has been
tampered with by another person, check that your settings are correct.
• WARNING!
It is important to keep in mind that your body undergoes changes, even
daily changes, that a computer cannot account for. If your physical
condition is not excellent, or if you feel any physical problems, do not
dive!
• WARNING!
The normal functions of the product could be disturbed by strong
electromagnetic interference.
In this case, simply reboot the product to restore normal function,
following the instructions provided in this manual (see “Reset”) and use
the product in another position.
• WARNING!
Strictly avoid pressing on the side grill of the sensor with your fingers,
especially if the sensor compartment is full of water, because this could
distort the measurement of zero, and could therefore result in an incorrect
measurement of depth during the next dive.
In FREE mode, if you notice a measurement of anything other than
zero on the surface, you need to reset the device to zero out the sensor
measurement (see the instructions and warnings on using the RESET
further on in this manual) or wait a few hours for the system to reestablish
the correct zeroing.
