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 suicient 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.

FUNCTIONS OF THE APNEA COMPUTER
Software
a) MSST Minimum Suggested Surface Time
The MSST is minimum interval of time on the surface that is suggested between
two dives to reduce freediving risks.
• WARNING!
The minimum suggested recovery times between two dives indicated by
the MSST calculation can reduce, but not eliminate, the risks of accidents
caused by freediving, such as syncope, Taravana, and/or hemoptysis,
because there are many other factors to consider, such as age, body
mass, training, physical condition, pre-existing medical conditions (both
known and unknown to the diver), and more, which the Apnea computer
software cannot calculate.
The MSST is calculated dierently for two depth brackets:
• To a depth of 30 meters or less, the MSST is twice the dive time in seconds,
rounded up to the next whole minute. That means that for a dive with a dive
time of 1 minute 40 seconds, the MSST is 4 minutes.
• For depths greater than 30 meters, it is the maximum depth reached during
the dive divided by 5 and rounded up to the next whole minute. So, for a dive
to a maximum depth of 41.00 meters, the MSST will be 9 minutes.
Calculation of the MSST is enabled by default. It can be disabled using the
corresponding option in the “FREE SET” menu.
When MSST is active it will be displayed in the middle of the screen with the
label “MSST” flashing until the countdown has concluded (the clock reaches
00:00).

b) Hydration
• WARNING!
It is well known that dehydration, along with other freediving conditions
and the freediver's physical condition, can contribute to freediving
accidents. To reduce these risks, the Apnea computer periodically
reminds the freediver to hydrate by drinking water.
In every session, the reminder to hydrate will be displayed about every
2 hours.
The 2-hour interval count starts at the beginning of the first dive in the
session.
The reminder is only visual, cannot be deactivated beforehand in the SET
menu, and only appears while on the surface between two dives.
Press any button to clear the reminder.
To avoid the reminder being closed manually, it is shown on the surface.
The countdown for the next 2-hour interval will start when the previous
reminder is closed.
c) MSST Alarm
The audible alarm for an MSST violation is emitted when the freediver goes back
under water before the MSST elapses.
This alarm stops automatically after 10 seconds, or can be stopped manually by
pressing any button.
This alarm can be switched o in the ALARMS menu.
MSST violations do not result in penalties in the calculation of the next MSST.
b) Depth Exceeded Alarm
The Depth Exceeded audible alarm sounds when the freediver exceeds the
depth value set in the corresponding section of the ALARMS menu, if activated.
This alarm stops automatically after 30 seconds, or can be stopped manually by
pressing any button.
This alarm can be switched o in the ALARMS menu.
10
e) Dive Time Exceeded Alarm
The Dive Time Exceeded audible alarm sounds when the freediver exceeds
the Dive Time value set in the corresponding section of the ALARMS menu,
if activated.
This alarm stops automatically after 30 seconds, or can be stopped manually by
pressing any button.
This alarm can be switched o in the ALARMS menu.
Logbook
• Approx. 30 hours with sampling every 2 seconds, or approximately 15 hours
with sampling every second.
If the memory becomes completely full, the oldest dives will be deleted to make
room for new dives.
Fitness function: step counter
The step counter is a stand-alone application and only starts running when
the user is in that application. Therefore, the application does not run in the
background.
For the most precise calculation, it's important to set the “Height and Weight”
values correctly.
The step counter application consumes battery more quickly.
Step counting is based on the interpretation of data provided by the
accelerometer only. Therefore, step counting accuracy has some limitations:
• It depends strictly on where the watch is worn (wrist, belt, ankle, etc.).
• It depends strictly on how the user wears it (for example, a watch that is loose
around the wrist will not count steps correctly).
• It also depends on the type of activity. Certain activities generate false positives
(moving the hands, car/motorcycle/train/subway trips, washing dishes, etc.).
• It depends on how long the activity lasts. Steps are only counted once a given
number have been detected in a row.
• The accuracy of the step counter application cannot be guaranteed for 100%
of the population because individual users walk and move dierently.
• The maximum identification frequency of steps is 3Hz (3 steps per second).
