Welcome to SCUBAPRO dive computers and thank you for purchasing the Aladin Sport.
You are now the owner of an extraordinary partner for your dives. This manual provides you
with easy access to SCUBAPRO state-of-the-art technology and key Aladin Sport features
and functions. Should you wish to know more about SCUBAPRO diving equipment, please
visit our website at www.scubapro.com.
IMPORTANT
Please carefully read and understand the Read First booklet that is included in the package before
using your SCUBAPRO Aladin Sport.
WARNING
• The Aladin Sport has a depth rating of 120m/394ft.
• If 120m/394ft is exceeded, “---“ will appear in the depth eld and the decompression algorithm
will not calculate correctly.
• Diving at oxygen partial pressures higher than 1.6bar (corresponding to a depth of 67m/220ft when
breathing compressed air) is extremely dangerous and could lead to serious injury or death.
WARNING
• The Aladin Sport is delivered in deep sleep mode with the display off. You must activate the Aladin
Sport by pressing and holding the left or right button before the rst dive. The Aladin Sport will not
start the dive mode or may show the wrong depth value if activation is not done before immersion.
The Aladin Sport dive instrument is compliant with the European Union directive 2014/30/EU.
Standard EN 13319: 2000
The Aladin Sport dive instrument is also compliant with the European standard EN 13319: 2000 (EN 13319: 2000 – Depth

this manual, such scrolling is indicated
by left-pointing arrows running along
the bottom of the display.
Time of day display:
which is quickly replaced by the day of the
week. This is referred to as the “time of
day” display.
In the time of day display, if there is
remaining saturation from the last dive or
from a change of altitude, the Aladin Sport
may indicate the “Do not y” icon, “Do not
dive” icon or “Altitude” icon or a combination
of the icons depending on the situation.
NOTE: Most navigation descriptions
F
in this manual start from the time of

English
The Aladin Sport switches on:
• Automatically, upon submerging in
water or when triggered by a change in
atmospheric pressure.
• Manually, by pushing and holding either
the left or right button.
If switched on with the left button, all
display segments appear for 5 seconds.
Afterwards, the display shows the time of
day, the date and a scrolling SCUBAPRO
ALADIN SPORT USER MANUAL
From the time of day display you can check
the desaturation time* with a press-andhold of the right button. Desaturation time
is determined either by oxygen toxicity,
nitrogen saturation or the regression
9
of microbubbles, depending on which
requires the longer time.
*Desat time is displayed only if there is
remaining saturation due to the last dive or
a change of altitude.
WARNING
For calculations of desaturation and no-y
time it is assumed that you are breathing air
while on the surface.
2.2.7 Checking the battery
condition
2.2.6 Checking the surface interval
From the time of day display you can check
the surface interval with a press-and-hold
of the right button (taking you directly to the
dive menu) and then another press-andhold (taking you to surface interval).
Surface interval is the elapsed time since
the end of your last dive; it is displayed as
long as there is remaining saturation.
From the time of day display you can check
the battery condition by pressing the left or
right button to scroll to the watch menu.
With a press-and-hold of the right button
you enter watch settings, then press the

WARNING
WARNING
• If the battery status graph shows only 2
zeros, the battery symbol will blink, both
on the surface and in dive mode, to alert
you of a dangerous situation. At this point
the battery may not have enough energy to
nish a dive. In such a case, audible alarms
and attention messages are disabled, the
backlight is deactivated, and you run the
risk of a computer malfunction. Do not let
the battery reach this condition!
• Always replace the battery when the steady
battery symbol appears (3 zeros).
NOTE: Logbook information is not lost
F
even when the battery is removed for
an extended period of time.
11
2.2.8 Active backlight
(4°C/40°F and below) the low battery
warning may come on within the
rst dive. For temperatures between
4°C/40°F and 20°C/68°F the life of
a new battery will fall somewhere
between 1 and 20 1-hour dives.
The Aladin Sport monitors the battery
level throughout every dive, and if
the available energy drops below the
warning threshold, the Aladin Sport
will automatically disable the backlight
to prevent a computer shut-down.
The display of the Aladin Sport can be
illuminated both on the surface and under
water. The backlight can be activated with
a press-and-hold of the left button.
The light will turn off automatically with a
default duration of 10 seconds. However,
duration can be adjusted between 2 and 12
seconds. The backlight can also be set to
“push on/push off” in which case the light
stays on until you press the button again.
To set backlight duration:
• Starting from the time of day display,
push the left or right button to get to the
dive menu screen, then press-and-hold
the right button.
• Press the right button 3x to get to the
user settings screen, then press-andhold the right button.
• Press the right button once to get to the
backlight duration screen, then pressand-hold the right button.
• Press the left or right button to choose
your backlight duration or to set push
on/push off, then lock in your choice

surface.
If the alarm clock is “on” the time of day
display shows the alarm clock/transmit
symbol.
When the alarm is triggered, the alarm
clock/transmit symbol ashes and special
attention beeps sound for 30 seconds or
until you press a button.
12
NOTE: Repeated activation of the
F
backlight will reduce battery life.
NOTE: Keeping the backlight on
F
permanently represents a severe
strain on the battery. In warm waters
(20°C/68°F and above), a new battery
can sustain 20 to 40 1-hour dives with
the backlight always on. In cold waters

2.3 SOS mode
WARNING
• Serious injury or death may result if you
do not seek immediate treatment should
any signs or symptoms of decompression
sickness occur after a dive.
• DO NOT dive to treat symptoms of
decompression sickness!
• Diving in SOS mode is extremely dangerous
and you must assume full responsibility for
such behavior. SCUBAPRO will assume no
liability.
NOTE: A diving accident can be
F
analyzed at any time in the logbook
and downloaded to a PC by means of
the Bluetooth interface and LogTRAK
software.
3. DIVING WITH YOUR
ALADIN SPORT
English
SOS mode (lock duration 24 hours) and surface
interval from the dive
If you remain above a depth of 0.8m/3ft for
more than 3 minutes without observing a
prescribed decompression stop, the Aladin
Sport will automatically switch into SOS
mode after the dive and remain there for
24 hours. The dive will be entered in the
logbook with “SOS.”
Push the right button to see the “SOS”
symbol (the SOS mode will be unlocked
after 24 hours).
While in SOS mode, the Aladin Sport
cannot be used for diving. It can, however,
be used in gauge mode (see chapter:
Gauge Mode, section: Diving in gauge
mode).
NOTE: Diving within 48 hours after
F
exiting SOS mode will result in
shorter no-stop times or longer
decompression stops.
3.1 Terminology/Symbols
The information on the display of the Aladin
Sport varies depending on the kind of dive
and the dive phase.
NOTE: For information on diving with

3.1.3 Nitrox information
(O2 information)
For dives with compressed air in normal
recreational diving, nitrogen is the decisive
gas for decompression calculations. When
diving with nitrox, the risk of oxygen toxicity
rises with the increase of the fraction of
oxygen and the increase of depth; this can
limit dive time and max depth. The Aladin
Sport includes this in its calculations and
displays the necessary information:
O2% mix Fraction of oxygen: The fraction
of oxygen in the nitrox mixture can be set
between 21% (normal compressed air) and
100% in 1% increments. Your selected mix
will be the basis for all calculations.
ppO2 max Maximum allowed partial
pressure of oxygen: The higher the
fraction of oxygen in the mixture, the
shallower the dive depth at which this value
of the partial pressure of oxygen is reached.
The depth at which the ppO2 max is reached
is called Maximum Operating Depth (MOD).
When you enter the settings for the gas
mixture, the Aladin Sport will display
the ppO2 maximum limit setting and the
corresponding MOD. The Aladin Sport
warns you audibly and visually once the
depth is reached at which the ppO2 reaches
the maximum allowed value.
NOTE: The default setting of ppO2
F
max is 1.4bar. The value of ppO2
max can be set between 1.0bar and
1.6bar at the gas settings. It can also
be changed to “off” (--) which requires
Code 313. The CNS O2% value/alarm
is not inuenced by the selected ppO2
max setting.
CNS O2% Oxygen toxicity: With the
increased percentage of oxygen, the
oxygen in the tissues, especially in the
central nervous system (CNS), becomes
important. If the partial pressure of oxygen
rises above 0.5bar, the CNS O2 value
increases; if the partial pressure of oxygen is
below 0.5bar, the CNS O2 value decreases.
The closer the CNS O2 value is to 100%,
the closer the limit where symptoms of
oxygen toxicity can occur.
During the dive, the depth at which ppO2
reaches 0.5bar with various commonlyused mixes is as follows:
MIX DEPTH in
meters
DEPTH in
feet
21% 13m 43ft
32% 6m 20ft
36% 4m 13ft

ALADIN SPORT USER MANUAL
WARNING
Nitrox diving should only be attempted by
experienced divers after proper training from
an internationally recognized agency.
3.2 Attention messages and
alarms
The Aladin Sport draws the diver’s attention
to certain situations and warns of unsafe
diving practices. These attention messages
and alarms are visual and/or audible.
3.2.1 Attention messages
Attention messages are communicated
visually using symbols, letters or ashing
gures. In addition, 2 short audible
sequences can be heard (in an interval of
4 seconds) in 2 different frequencies under
water.
Attention messages come up in the
following situations:
• Maximum operating depth/ppO2 max is
reached.
• Set max depth is reached.
• Oxygen toxicity reaches 75%.
• No-stop time is less than 3 minutes.
• Prohibited altitude (surface mode).
• Entering decompression (when diving
with MB L0).
• Half of set dive time is reached.
• Set dive time is reached.
• Depth for tank switch has been
reached.
Diving with MB levels (L1-L5):
• MB no-stop time = 0.
• MB level stop is ignored.
• MB level is reduced.
• Entering decompression when diving
with MB level L1-L5.
3.2.2 Alarms
Alarms are provided visually by ashing
symbols, letters or gures. In addition, an
audible sequence in one frequency can
be heard during the whole duration of the
alarm.
An alarm occurs in the following situations:
• Oxygen toxicity reaches 100%.
• Ignored decompression.
• Exceeding the prescribed ascent rate.
• Altitude alarm.
• Low battery alarm (without audible
alarm): battery icon appears if battery
has to be replaced.
• Apnea mode alarm.
NOTE: Audible attention messages
F
can be switched off in the watch
settings mode (by pressing the right
button 5x to the sounds screen) or
in LogTRAK. With LogTRAK sounds
can be switched off selectively or
completely.
WARNING
If you turn off all sound you will have no
audible warnings. Without audible warnings
you could inadvertently nd yourself in
potentially hazardous situations which could
result in death or serious injury.
WARNING
Serious injury or death may result from failing
to immediately respond to alarms provided by
the Aladin Sport.
3.3 Preparation for the dive
It’s important to check the settings of the
Aladin Sport, especially before the rst dive.
All settings can be checked and changed
directly on the Aladin Sport or by using
LogTRAK and a PC.
3.3.1 Function check
To test the display, turn on your Aladin Sport
with a press-and-hold of the left button. Are
all elements of the display activated? Do not
use your Aladin Sport if the display does
not show all elements. (When switching on
the Aladin Sport with the right button the
test display will not appear.)

WARNING
Always check the battery capacity before each
dive. See chapter: System and Operation,
section: Check the battery.
3.3.2 Setting the gas mixture and
ppO2 max
To set the gas mixture, the Aladin Sport
must be in the dive display (showing time
of day, temperature and gas percentage):
1. Press-and-hold the right button to get
to the GAS screen, then press-andhold the right button again to get to the
GAS1 O2 menu.
NOTE: Without conrmation via a
F
press-and-hold of the right button the
display will disappear after 3 minutes
and your entries will not be accepted.
Automatic reset of the O2% mix to
21% can be set between 1 and 48
hours or to “no reset” (default).
WARNING
Before every dive and after changing the tank,
make sure that the settings for the gas mixture
correspond to the current mixture being used.
An incorrect setting will cause the Aladin
Sport to miscalculate the dive. If the fraction
of oxygen is set too low, oxygen poisoning
can occur without warning. If the value is set
too high, decompression sickness may occur.
Inaccuracies in the calculations are carried
over to repetitive dives.
2. Conrm that you wish to change the
oxygen fraction of gas 1 with a pressand-hold of the right button.
3. By pressing either the left or right button
you can change the oxygen fraction in
increments of 1%. The Aladin Sport will
display the current fraction of oxygen,
the maximum partial pressure limit (ppO2
max) and the MOD.
4. Conrm your selected percentage with
a press-and-hold of the right button.
5. Next, by pushing the left or right button
you can change the ppO2 max for your
chosen fraction of oxygen down to
1.0bar. The Aladin Sport will now display
the corresponding MOD for the new
ppO2 max.
6. Conrm your ppO2 max setting with a
press-and-hold of the right button.

ALADIN SPORT USER MANUAL
3.4.2 Setting bookmarks
During the dive you can create bookmarks
in your dive prole with a press of the
left button. An audible signal conrms
the creation of the bookmark. These
bookmarks will be graphically displayed in
the dive prole of LogTRAK.
3.4.3 Dive time
All time spent below a depth of 0.8m/3ft is
displayed as dive time in minutes. The time
spent above 0.8m/3ft is counted as dive
time only if you once again descend below
0.8m/3ft within 5 minutes.
While the dive time is running, the colons
to the right of the gures are ashing in
1-second intervals.
The maximum dive time displayed is 199
minutes. If a dive lasts longer than 199
minutes the dive time display starts again
at 0 minutes.
3.4.4 Current depth/O2% mix
Current depth is given in 10cm increments
in the metric setting and 1ft increments in
the imperial setting.

alarm): If half of the set maximum dive
time has elapsed, an audible signal will
sound and the symbol ashes for
1 minute.
When the set dive time has elapsed
an audible alarm sounds and the dive
time starts ashing.
ALADIN SPORT USER MANUAL
Max depth
CNS O2%
Max depth is displayed only if it exceeds
the current depth by more than 1m/3ft
(maximum indicator function). In the
absence of max depth the Aladin Sport
displays temperature.
The O2% mix is displayed as long as the
CNS O2% is less than 50%. More than 50%
and the CNS O2% is displayed.

3.4.6 Set max depth reached
WARNING
If the set max depth has been reached (default
40m/130ft) and the depth alarm is turned on,
the alarm tone sounds and the depth display
ashes. Ascend until the depth stops ashing.
3.4.7 Ascent rate
Too fast
ascent
indicator
Ascent rate
Optimal ascent rate varies depending on
depth between 7 and 20m/min (23 and
67ft/min). It is displayed as a percent of
the reference variable ascent rate. If the
ascent rate is greater than 100% of the set
value, the vertical black arrow with “SLOW”
appears. If the ascent rate exceeds 140%,
the arrow starts ashing.
The Aladin Sport provides an audible alarm
if the ascent rate is 110% or greater. The
intensity of the alarm increases in direct
proportion to the degree that the prescribed
ascent rate is exceeded.
WARNING
The prescribed ascent rate must be observed
at all times! Exceeding the prescribed ascent
rate can lead to microbubbles in the arterial
circulation which can lead to serious injury or
death due to decompression sickness.
• In case of an improper ascent the Aladin
Sport may require a decompression
stop, even within the no-stop phase,
because of the danger of microbubble
formation.
• The decompression duration necessary
for the prevention of microbubbles can
increase massively if the ascent rate is
exceeded.
• From great depths a slow ascent
may cause heightened saturation
of tissues and an extension of both
decompression duration and total
ascent time. At shallow depths, a slow
ascent may shorten the decompression
duration.
• Display of the ascent rate has the
priority over “CNS O2”.
Excessive ascent rates for longer periods
are entered in the logbook. The following
ascent rates correspond to the 100% value
in the Aladin Sport.

ALADIN SPORT USER MANUAL
3.4.8 Partial pressure of oxygen
(ppO2 max)/Maximum
operating depth (MOD)
The maximum partial pressure of oxygen
(ppO2 max), with a default of 1.4bar,
determines the Maximum Operating Depth
(MOD). Diving deeper than the MOD
exposes you to oxygen partial pressures
higher than the set maximum level.
The ppO2 max, and consequently the MOD,
can be reduced manually when setting the
gas. See chapter: Settings, section: Gas
menu.
WARNING
The MOD is a function of ppO2 max and the
mixture used. If during the dive the MOD is
reached or exceeded, the Aladin Sport sends
an audible attention message and the MOD is
displayed (ashing) in the lower left corner. If
this occurs, ascend to a depth shallower than
the displayed MOD in order to diminish the
danger of oxygen poisoning.
WARNING
The MOD should not be exceeded. Disregarding
the warning can lead to oxygen poisoning.
3.4.9 Oxygen toxicity (CNS O2%)
English
The Aladin Sport calculates oxygen toxicity
based on depth, time and gas mixture,
and displays it in the lower right corner
when the value is greater than 50%. The
toxicity is expressed in 1% increments of a
maximum tolerated value (CNS O2 clock).
The symbol “CNS O2” is displayed together
with the percentage.
WARNING
An audible attention signal starts if oxygen
toxicity reaches 75%. The symbol “CNS O2%”
ashes.
Ascend to a shallower depth to decrease oxygen
loading, and consider terminating the dive.
ALADIN SPORT USER MANUAL
19
WARNING
When oxygen toxicity reaches 100%, an audible
alarm sounds every 4 seconds. “CNS O2” and
the percentage value ash, indicating the
danger of oxygen toxicity! Start procedure for
terminating the dive.
NOTE:
F
• During an ascent, and if the CNS O2%
value does not increase (due to a
lower partial pressure of oxygen), the
audible warning is suppressed.
• During an ascent, the display of the
oxygen toxicity is replaced by the
ascent rate. If the ascent is stopped,
the display changes back to the
indication of the CNS value.
• The Aladin Sport displays CNS O2%
values exceeding 199% with 199%.
• The Aladin Sport displays CNS O2%
values above 50%.
3.4.10 Decompression information
NO STOP and the no-stop time (in minutes)
are displayed if no decompression stops
are necessary.
WARNING
If no-stop time drops below 3 minutes, an
audible attention signal is activated and the
no-stop value begins to ash. If no-stop time
is less than 1 minute, the no-stop display
shows the ashing value “0”.
In order to prevent a decompression dive,
ascend slowly until the no-stop time is 5
minutes or more.
WARNING
Decompression diving requires advanced
training from a recognized agency. Do not
attempt decompression diving without proper
training from a recognized agency.
