DIVING ENGINEERS

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
gauges and combined depth and time measuring devices – Functional and safety requirements, tests methods).

display, longer words are scrolled. In
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

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
right button 6x to scroll to the battery status

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

From the time of day display you can
switch off the Aladin Sport by pressing and
holding both buttons simultaneously. On
the surface the Aladin Sport switches off
automatically after 3 minutes of non-use.

2.2.10 Alarm clock

The alarm clock tone works only at the
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 inuenced 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
GAS1 O2 menu.

NOTE: Without conrmation 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. Conrm 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. Conrm 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. Conrm 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 prole with a press of the
left button. An audible signal conrms
the creation of the bookmark. These
bookmarks will be graphically displayed in
the dive prole 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.

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.

formation of microbubbles, decompression
can increase massively if a decompression
stop is ignored. Descend to the prescribed
decompression stop depth immediately!

3.4.12 Total ascent time

Total Ascent

Time

As soon as decompression stops are
necessary, the Aladin Sport shows the
total time of ascent. This includes the
ascent time from the current depth to the
surface as well as all decompression stop
obligations.

NOTE: The total time of ascent

F

is calculated on the basis of the
prescribed ascent rate. Total time of
ascent can be subject to change if
the ascent rate is not ideal (100%).
Ascent time greater than 99 minutes
is displayed as “ – – ”.

WARNING

On all dives with the Aladin Sport, make a safety
stop for at least 3 minutes at a depth of 5m/15ft.

3.4.13 Safety stop timer

English

When the surface is reached during the
decompression alarm, the “DECO STOP”
arrow, the decompression stop duration,
and decompression stop depth continue
ashing in order to point to the risk of a
decompression accident. The SOS mode
is activated 3 minutes after the dive if
corrective action is not taken. If the total
(cumulative) duration of the decompression
alarm is longer than one minute, it is
entered in the logbook.

ALADIN SPORT USER MANUAL

Safety Stop Icon

Safety stop time (minutes, seconds)

The safety stop timer displays the time a
diver should spend at the safety stop depth
at the end of the dive. The timer starts
automatically when depth is shallower than
5m/15ft and counts back from 3 minutes
(default) to zero. It can be restarted manually
any number of times. The duration of the
timer can be set between 1 and 5 minutes.

21

The safety stop timer will be activated under
the following conditions: depth <5m/15ft;
no-stop display of 99 min; the gauge mode
is switched off; stop time is selected (1-5
min) in the scuba mode menu.

You can activate the safety stop timer by
pressing the left button. The timer begins
to count backwards and a bookmark will
be created in the dive prole. If you press
again, the timer will start again from the full
value.

The safety stop timer will switch off
automatically if the depth exceeds

6.5m/21ft or the no-stop phase is shorter

Desaturation time

5 minutes after a dive the Aladin Sport
shows the desaturation time, the no-y
time, the no-dive warning (if applicable),
the current altitude class and the prohibited
altitude class – see chapter: Diving with

your Aladin Sport, section: Prohibited
altitude.

No-y time is the time in hours that should
pass before ying. It is displayed until the
value counts down to 0 hours.

WARNING

Flying while the Aladin Sport displays the “do
not y” icon may lead to serious injury or death
from decompression sickness.

22

After reaching the surface (<0.8m/3ft) the
Aladin Sport remains in dive mode for 5
minutes. The delay allows for surfacing for
a short period for orientation.

After 5 minutes, the dive is closed and is
entered into the logbook. The desaturation
time, the no-y time, the no-dive warning
(if applicable), the current altitude class and
the prohibited altitude class are displayed
for 3 minutes, after which the computer
turns off.

WARNING

For calculations of desaturation and no-y time
it is assumed that you are breathing air while
on the surface.

WARNING

If the “no-dive” warning is visible during the
surface interval, you should not undertake
another dive.

To check the elapsed surface interval and
oxygen toxicity, press-and-hold the right
button.

Surface interval

Oxygen toxicity

ALADIN SPORT USER MANUAL

Desaturation time is determined either by
oxygen toxicity, nitrogen saturation or the
regression of microbubbles, depending on
which requires the longer time.

No-dive warning

If the Aladin Sport detects a situation of
increased risk (due to the potential of
microbubble accumulation from previous
dives or a CNS O2 level above 40%), the
“no-dive” symbol will appear on the display.

The duration of the no-dive warning is
visible in the dive planner menu. The Aladin
Sport recommends this as a minimum
surface interval in order to reduce the
number of microbubbles and/or to reduce
the CNS O2 level below 40%.

NOTE: You should not undertake a

F

dive as long as the no-dive warning
message is displayed on the computer
screen. If the warning is prompted
by microbubble accumulation (as
opposed to CNS O2 over 40%) and you
dive anyway, you will have shorter no­stop times or longer decompression
times. Moreover, the duration of the
no-dive warning at the end of the dive
can increase considerably.

3.6 Diving in mountain lakes

3.6.1 Altimeter

The altitude adjustment (see chapter:
SETTINGS, section: Altitude adjustment)
does not affect altitude classes nor any
calculations.

3.6.2 Altitude classes

The Aladin Sport measures the
atmospheric pressure every 60 seconds,
even while the display is switched off. If
the computer detects a sufcient increase
in altitude, it switches on automatically
and indicates the new altitude class (1-4)
and the desaturation time. Desaturation
time indicated at this moment refers to the
adaptation time at this altitude. If the dive
starts within this adaptation time, the Aladin
Sport treats it as a repetitive dive, since the
body is off-gassing.

Altitude is divided into 5 classes, which
are inuenced by barometric pressure.
That is why the dened altitude classes
overlap on their fringes. If a mountain lake
is reached, the altitude class is indicated
at the surface (time of day display), in the
logbook and in the dive planner with a
stylized mountain icon and the current
altitude class. The altitude from sea level
to approximately 1000m/3280ft is not
indicated. In the following diagram, you
can see the approximate breakdown of the
altitude classes:

3.6.3 Prohibited altitude

Ascent to altitude class 3 and 4 is
prohibited. Maximum allowed altitude:
2650m/8694ft.

WARNING

At the surface, the Aladin Sport shows, via ashing
altitude class number, the altitude to which you
may not rise. The ascent prohibition is displayed
together with the current altitude class.

Example:

3.7 Gauge mode

Gauge mode does not support the
calculation of no-stop time or the supervision
of decompression. Supervision of ppO2
max and CNS O2% are also switched off. In
gauge mode the Aladin Sport displays no
information on microbubble development
or settings for gas mixture. MOD and
microbubble levels cannot be set and the
dive planner cannot be selected.

WARNING

In gauge mode, ALL audible and visual alarms
and attention messages are turned off and the
Aladin Sport displays depth, dive time and max
depth.

You are at 1200m/3937ft (altitude class

1) and you may ascend to class 2 only
(2650m/8694ft). You may not rise to the
altitude classes 3 or 4.

WARNING

If an ascent to a prohibited altitude is detected,
an audible alarm sounds for 1 minute. Descend
to a lower altitude.

3.6.4 Decompression dives in
mountain lakes

In order to assure optimal decompression
even at higher altitudes, the 3m/10ft
decompression stage is divided into a
4m/13ft stage and a 2m/7ft stage in
altitude classes 1, 2 and 3. The prescribed
decompression stop depths are in sequence
(2m/7ft, 4m/13ft, 6m/20ft, 9m/30ft…).

If atmospheric pressure is below
620mbar/8.99psi (altitude higher than
4100m/13450ft above sea level), the
Aladin Sport switches automatically to
gauge mode and no decompression data
is calculated or displayed. In addition, the
dive planner is no longer available. For
more information on diving in gauge mode,
refer to the following section.

3.7.1 Switching the gauge mode
on and off

Gauge mode can be switched on and off at
the surface when there is no desaturation,
and when no dive in gauge mode has been
made in the last 48 hours.

WARNING

• Dives in gauge mode are performed at your
own risk!

• After diving in gauge mode, the Aladin Sport
cannot be used as a dive computer for 48

3.8 Apnea mode

3.8.1 Switching the apnea mode
on and off

The apnea mode can be switched on and
off, like the gauge mode, when there is no
desaturation, and when no apnea dives
have been made in the last 48 hours.

WARNING

Apnea diving after scuba diving is
not recommended. Check the latest
recommendations from your instructor or
diving organization.

25

WARNING

The Aladin Sport doesn’t track your nitrogen
intake while in apnea mode. Therefore, the
no-y time after apnea diving is set to 48
hours. Also, scuba diving after apnea diving
is recommended only after sufcient surface
time. Check the latest recommendations from
your instructor or diving organization.

WARNING

All breath-hold dives include a risk of shallow
water blackout; that is, a sudden loss of
consciousness due to oxygen starvation.
The apnea mode is comparable to the gauge
mode – it doesn’t have a dive algorithm and
all decisions are left to the diver. Therefore
SCUBAPRO recommends:

Procedure:

1. From the dive display press-and­hold the right button (“GAS” menu
appears). Press the right button 4x and
“ALGORITHM” menu is displayed.

2. Conrm with a press-and-hold of the
right button that you wish to activate or
deactivate the apnea mode.

3. “Scuba”, “Gauge” or “Apnea” starts
ashing.

4. By pressing the right button you can
scroll between modes and select the
apnea mode.

5. Conrm your setting with a press-and­hold of the right button.

WARNING

SCUBAPRO highly recommends professional
training in apnea diving techniques and
physiology before conducting breath-hold
dives. No dive computer can replace the
need for proper dive training. Insufcient or
improper training may cause you to commit
errors that can lead to serious injury or death.

1. Never apnea dive alone.

2. Make only apnea dives that your
education and physical condition allow.

In apnea diving fast descents and ascents
are allowed. Therefore, the Aladin Sport
uses a faster sampling of depth for higher
accuracy. The Aladin Sport updates the
display of maximum depth every 0.25
seconds, and the logbook is updated every
second.

WARNING

Deep repetitive apnea dives are not
recommended; leave enough recovery time
between your apnea dives.

In apnea mode the dive can be started
manually with a press-and-hold of the right
button. This function allows a fast sampling
to start straight from the surface. The

ALADIN SPORT USER MANUAL

automatic start of an apnea dive will occur
at a depth of 0.8m/3ft.
Once activated, the apnea mode will run
15 minutes after surfacing. This allows you
to start a repetitive apnea dive with precise
data in the logbook. The surface mode can
be stopped with a press-and-hold of the
right button.

The Aladin Sport’s apnea mode has special
alarms and functions tailored to apnea
diving and apnea training. You can select
multiple alarm functions at the same time.
The alarm functions set-up is explained
in the chapter: Settings, section: Apnea
menu.

3.9 Diving with microbubble
(MB) levels

Microbubbles (MB) are tiny bubbles that
can build up inside a diver’s body during any
dive and normally dissipate naturally during
an ascent and on the surface after a dive.
Dives conducted within no-stop times and
the observance of decompression stops do
not prevent the formation of microbubbles
in the venous blood circulation.

Dangerous microbubbles are those
migrating into the arterial circulation. The
reasons for the migration from the venous
blood circulation to the arterial circulation
can be a great many microbubbles
collecting in the lungs. SCUBAPRO has
equipped the Aladin Sport with a new
technology to help protect divers from
these microbubbles.

With the Aladin Sport, you can choose –
according to your specic needs – a MB
level that will provide a level of protection
from microbubbles. Diving with MB levels
includes additional ascent stops (level
stops); this slows the ascent process,
giving the body more time to desaturate.
This works contrary to the formation of the
microbubbles and increases safety.

The Aladin Sport features 6 microbubble
levels (L0-L5). Level L0 corresponds to
SCUBAPRO’s well-known decompression
model ZH-L16 ADT and does not require
level stops due to microbubble formation.
Levels L1 to L5 offer additional protection

from microbubble formation with level L5
offering the highest protection.

Similar to the display of information during
decompression dives or dives within no­stop time, the Aladin Sport displays depth
and duration of the rst level stop as well as
the total time of ascent as soon as the MB
no-stop time has run out. As the MB no­stop time is shorter than the ordinary no­stop time you will be required to perform a
stop (level stop) sooner than a diver using
level L0.

If you ignore a required level stop, the Aladin
Sport will simply step down to a lower MB
level. In other words, if you choose level L4
prior to the dive, and during the dive you
ignore the L4’s recommended stops, the
Aladin Sport will automatically adjust the
setting to level L3 or lower.

3.9.1 Comparison of dives with MB
level L0 and MB level L5

When two Aladin Sport dive computers are
used simultaneously, with one unit set to a
MB level of L5 and the other to a MB level
of L0, the no-stop time for the L5 unit will
be shortened and more level stops will be
required before the diver has the obligation
of a decompression stop. These additional
level stops help dissipate microbubbles.

cascading to a lower MB level, all requested
level stops must be observed.

The deepest level stop is displayed in
meters/feet. The display “2: 3m” means
that a level stop of 2 minutes at a depth
of 3m/10ft has to be observed. Deco
information relative to L0 is shown on an
alternate display (see chapter: Diving

WARNING

The warning “MB level reduced” is activated
if you ascend more than 1.5m/5ft above the
required level stop. The Aladin Sport reduces
the MB level, an attention beep* sounds and
the new MB level is shown in the lower left
corner. To complete the dive without shifting
down to an even lower MB level the new level
stop must be observed.

* Attention beeps can be suppressed. See
chapter: Settings, section: Switching the

sound on and off.

Total ascent time

NOTE: The total time of ascent

is calculated on the basis of the
prescribed ascent rate. Total time of
ascent can be subject to change if the
ascent rate is not ideal (100%).

Decompression obligation

The Aladin Sport calculates and displays
level stops to reduce microbubble
formation, but it also calculates the diver’s
decompression data.

WARNING

Avoid decompression dives when diving with
MB levels.

How to avoid decompression stops:

• Check ordinary no-stop time by
pressing the right button until L0
appears.

WARNING

At the beginning of a decompression phase an
attention beep sounds and the symbol ashes
for 8 seconds. In order to prevent a dive with
long decompression stops it is recommended
that you ascend a few meters/feet upon
seeing this message.

30

Total Ascent Time

(including level stop)

The Aladin Sport displays the level stop
information and the total time of ascent.
This includes the time of ascent as well as
all level stops.

If decompression stops become obligatory,
the “DECO” symbol will be displayed. The
total ascent time will now also include a
decompression stop.

Level stop and deco stop

When the level stop depth equals the depth
of the rst obligatory decompression stop,
and if you are within 1.5m/5ft of the stop
depth itself, the Aladin Sport shows STOP
DECO and STOP (level stop). The indicated
duration refers to the level stop duration.

ALADIN SPORT USER MANUAL

Since level stops are more restrictive
than decompression stops, when all
decompression obligations have been
observed the display changes from STOP
DECO to STOP only.

3.9.5 Completing a dive with MB
levels

A dive with MB levels is completed the
same way as a dive without MB levels (see
chapter: Diving with your Aladin Sport,
section: Safety stop timer) except for the
following exceptions:

If the MB level has been reduced during the
dive, the Aladin Sport will display a ashing
MB level symbol and the current MB level
for 5 minutes after reaching the surface.
The dive is then completed and the Aladin
Sport changes to user mode with the MB
level switching back to the original MB
setting.

Repetitive dives and MB levels: If during a
dive a level stop is ignored and you start
another descent shortly afterwards, the
Aladin Sport might immediately request
level stops. To complete the dive with the
initially set MB level all level stops must be
observed.

3.10 PDIS (Prole Dependent
Intermediate Stop)

3.10.1 Introduction to PDIS

The main purpose of a dive computer is to
track your nitrogen uptake and recommend
a safe ascent procedure. Diving within the
so called no-stop limits means that at the
end of the dive you can ascend directly to
the surface, albeit at a safe ascent rate,
while for dives outside of the no-stop limit
(so-called decompression dives), you must
perform stops at certain depths below the
surface and allow time for excess nitrogen
to be expelled from your body before
nishing the dive.

In both cases, it can be benecial to stop
for a few minutes at an intermediate depth
between the maximum attained depth
during the dive and the surface or, in case
of a decompression dive, the rst (deepest)
decompression stop.

An intermediate stop of this kind is benecial
as soon as the ambient pressure at that
depth is low enough to ensure that your
body is predominantly off-gassing nitrogen,
even if under a very small pressure gradient.
In such a situation, you can still cruise along
the reef and enjoy the dive while your body
gets a chance to slowly release nitrogen.

In recent times, so called “deep” stops have
been introduced in some dive computers and
tables, dened as half the distance from the
dive’s maximum depth and the surface (or
the lowest decompression stop). Spending 2
or 15 minutes at 30m/100ft would result in
the same deep stop at 15m/50ft.

With PDIS, as the name suggests, the
Aladin Sport interprets your dive prole
and suggests an intermediate stop that
is a function of your nitrogen uptake so
far. The PDI stop will therefore change
through the course of the dive to reect
the continuously changing situation in
your body. Along the same lines, PDIS
will account for the accumulated nitrogen
from previous dives; hence, PDIS is also
repetitive-dive dependent. Conventional
deep stops completely ignore these facts.

The following gure quanties the extent
of PDIS and illustrates its dependence on

conceptual difference between PDIS and the rather rudimentary “deep” stops.

Specically, the gure compares 2 dive proles to a maximum depth of 40m/132ft that
are otherwise very different. Prole 1 stays at 40m/132ft for 7 minutes, then ascends to
30m/100ft for 3 minutes, followed by 12 minutes at 20m/65ft. Prole 2 stays less than 2
minutes at 40m/132ft, then ascends to 21m/69ft and stays there for 33 minutes. Both dive
proles are no-stop dives to the limit of entering decompression.

The solid line represents the PDIS depth as displayed on the computer screen during the
course of the dive for prole 1, the broken line represents the PDIS depth as displayed on
the computer screen during the course of prole 2. One can see that the displayed PDIS
depth increases as more nitrogen is accumulated in the body, but does so very differently in
the 2 dives due to the different exposure in the 2 proles. The PDI stop is carried out at 25
minutes for prole 1 and at 37 minutes for prole 2, followed by the safety stop at 5m/15ft.

The line made up of small solid dots, on the other hand, represents the depth that would
be displayed by a computer following the conventional deep stop method, and it would be
the same for the 2 dive proles. Deep stops completely ignore any facts about the dives
themselves aside from max depth.

3.10.2 How does PDIS work?

The mathematical decompression model
in the Aladin Sport, called ZH-L16 ADT
MB PMG, tracks your decompression
status by dividing your body into 16 so­called compartments and mathematically
following the uptake and release of
nitrogen in each with the appropriate laws
of physics. The various compartments
simulate parts of your body such as central
nervous system, muscles, bones, skin and
so on.

SAFETY STOP

PDI STOP

The depth of the PDI stop is calculated as
that at which the leading compartment for
the decompression calculation switches
from on-gassing to off-gassing, and the
diver is advised to perform a 2-minute
stop above the displayed depth (this is the
opposite of a decompression stop, where
you are asked to remain just beneath the
displayed depth). During this intermediate
stop, the body is not taking up any more
nitrogen in the leading compartment, but
rather releasing nitrogen (though under
a very small pressure gradient). This,

32

ALADIN SPORT USER MANUAL

combined with the relatively high ambient
pressure, inhibits bubble growth.

It should be noted that the 4 fastest
compartments, up to 10 minutes half­times, respectively, are not considered
for the determination of the PDI stop
depth. This is due to the fact that these
compartments are only “leading” for very
short dives, for which an intermediate stop
is not required at all.

NOTE: The PDI stop is not a mandatory

F

stop and it is NOT a substitute for the
3-5 minute safety stop at 5m/15ft.

WARNING

Even when performing a PDI stop, you still
MUST perform a safety stop at 5m/15ft for 3
to 5 minutes. Performing a 3 to 5 minute stop
at 5m/15ft at the end of any dive remains the
best thing you can do for yourself!

English

PDI Stop depth PDIS icon

When the calculated PDI stop is deeper
than 8m/25ft, the Aladin Sport shows it on
the display and continues to do so until you
reach the displayed depth during an ascent.
The displayed value changes during the
dive as the Aladin Sport tracks the uptake
of nitrogen in the 16 compartments and
updates the PDIS depth accordingly to
reect the optimum at all times.

3.10.3 Special considerations when

Switching to a higher oxygen concentration
mix during the dive inuences the PDI stop.
This needs to be accounted for, in line with
the predictive nature of multi-gas handling
in ZH-L16 ADT MB PMG.

When diving with more than one gas
mixture, the Aladin Sport displays the PDIS
depth according to the following rules:

• If the PDI stop calculated for the bottom

• If the PDI stop calculated for gas 1

In case of a missed gas switch, the Aladin
Sport reverts to the PDI stop for the actively
breathed mix.

is shallower than the switch depth to
gas d, then the displayed PDI stop is a
function of gas d.

NOTE: To use the PDIS feature, you

must enable PDIS (see chapter:
Settings, section: Setting PDIS).

The PDIS depth is shown in the lower left
corner, with the PDIS icon. During a no­stop dive, as soon as you reach that depth
during an ascent, a 2-minute countdown
will appear in place of the no-stop value
with the label STOP. In addition, the PDIS
label will blink. You can have one of 3
situations:

PDIS completed

Normal MB level stop

ALADIN SPORT USER MANUAL

33

• You have spent 2 minutes within
3m/10ft above the indicated depth.
The countdown timer disappears and
the PDIS value is replaced by the label
YES as an indication that you have
performed the PDI stop.

• You have descended more than

0.5m/2ft below the PDIS. The
countdown timer disappears and will
reappear again, starting at 2 minutes,
the next time you ascend to the PDIS
depth.

• You have ascended more than 3m/10ft
above the PDIS. The PDIS value and
countdown timer are replaced by the
label NO to indicate the fact that you
have not performed the PDI stop.

If the Aladin Sport is displaying a
decompression obligation when you reach
the PDIS depth during an ascent, all rules
apply the same way, but the 2-minute
countdown runs in the background and is
not displayed on the screen. The PDIS label,
however, will still be blinking, indicating that
you are in the PDIS range.

NOTE: The Aladin Sport issues no

F

warnings relating to a missed PDI
stop.

When diving with MB levels, PDIS follows
the same rules as described above. MB
levels, however, introduce stops earlier
and deeper than the L0 base algorithm. As
such, the PDIS display may be delayed and
for certain dives it may not be displayed at
all. This, for example, would be the case for
a shallow dive with air (21% oxygen) and
MB level L5.

same dive. Tank 1 contains the bottom mix
(gas 1), tank 2 the travel mix, and tank d
contains the deco mix (gas d).

Range of O2 fraction

During dives with 2 or 3 gas mixtures the
bottom mix (gas 1) contains the lowest
fraction of oxygen and gas d the highest
fraction of oxygen. The Aladin Sport will
only accept settings corresponding with
this order.

ALADIN SPORT USER MANUAL

WARNING

For gas mixtures having an oxygen percentage
of 80% or greater, the ppO2 is xed at 1.6bar
and cannot be altered in any way.

Procedure:

1. To enter the setting for the fraction
of oxygen and the ppO2 max (MOD)
for gas 1 (bottom mix), see chapter:
Settings, section: Gas menu.

2. Repeat the process for gas 2 and the
gas d. Note that in these cases the
resulting MODs correspond to the
depths at which you plan to switch from
gas 1 to gas 2 and from gas 2 to gas d
during the ascent phase.

3. If you set gas 2 and gas d to “– – O2%”,
the Aladin Sport will compute the dive
considering gas 1 only.

The Aladin Sport will only accept gas switch
depths (MOD gas 2/gas d) as input where
the maximum partial pressures of oxygen
(ppO2 max) are not exceeded.

NOTE:

F

• During the ascent an audible and
visual attention message will indicate
that you have reached the depth
which requires the change to gas 2
or gas d.

• Without confirmation, the display will
disappear after 30 seconds and your
entries will not be accepted.

• If the oxygen fraction of gas 2/gas d
is set to a value other than “--O2%” in
surface mode, and up to a depth of

0.8m/3ft, the Aladin Sport will display
“2G” or “3G” in the lower right corner
of the display instead of a percentage
value.

NOTE:

F

• If you occasionally dive nitrox, you can
use the automatic nitrox reset time to
normal air function. After the reset,
the oxygen fraction of gas 1 is set
to 21%, and the oxygen fractions of
gas 2 and gas d are set to “– – O2%”
(single gas dive).

Functions during a dive with 2 or 3 gas
mixtures

WARNING

Diving with 2 or 3 gas mixtures represents
a much higher risk than diving with a single
mixture, and mistakes by the diver may lead to
serious injury or death.

During dives with several gas mixtures,
always make sure you are breathing from
the tank you intended to breath from. Mark
all your tanks and regulators so they can
under no circumstances be mixed up!
Before every dive and after changing a
tank, make sure that each gas mixture is set
to the correct value for the corresponding
tank.

Predictive decompression prognosis

The calculation of decompression
data is based on the assumption that
the change(s) of gas mixture(s) will be
performed at the previously selected switch
depth(s) (MOD gas 2/gas d). If you ignore
a required change or change the mixture
belatedly, the Aladin Sport will readjust the
decompression calculation accordingly.
In case of an ignored switch the dive
computer will then base its calculations on
the assumption that you will ascend to the
surface without using the proposed gas.

Alternate displays during a dive with
2 gases

1. The default display shows the predictive
decompression prognosis, which
assumes the diver will switch to the
deco gas at the specied switch
depth. In the bottom left corner the
temperature is displayed unless the
current depth is 1m/3ft shallower than
the max depth, in which case the max
depth is displayed.

2. Upon pressing the right button, the
temperature and the current CNS%
are shown in the lower row. CNS%
will time out after 5 seconds while the
temperature remains.

3. Upon pressing the right button, “GAS

“GAS d” will time out after 5 seconds
unless the right button is pressed again.

4. Pressing the right button one more
time shows the O2% of the active gas
in the bottom right corner and the
decompression information in case the
dive would be nished with the currently
active gas (no switch to gas 2/deco gas).
This is the calculation that the Aladin Sport
would switch to in case, having reached
the switch depth(s), the diver did not
conrm the switch(es). The decompression
information and the O2% blink.

5. If an MB level greater than L0 is active,
pressing the right button one more time
shows the predictive decompression
information and, in the bottom left
corner, the currently active MB level.

6. Pressing the right button again
shows the predictive decompression
information relative to L0 together with
the L0 symbol at the bottom left.

7. One more right button push shows the
decompression information relative to
L0 if only the current gas is used, with
the decompression information and the
O2% of the current gas blinking.

8. Upon pressing the right button again, the
time of day appears in the middle row.

NOTE: All displays time out after 5

WARNING

When during an ascent a switch depth is
reached (MOD gas 2 or gas d), an audible
warning sounds and “GAS 2”/“GAS d”, its MOD
and O2% blink for 30 seconds.

Procedure:

1. Switch to the regulator with gas 2/gas d
and start breathing.

2. Conrm the change with a press­and-hold of the right button within
30 seconds. “GAS 2”/“GAS d” and
the oxygen fraction of gas 2/gas d
is displayed for 5 seconds without
blinking.

To interrupt the switch process at any
point, either press the right button until
the original gas is again active, or do not
conrm the gas change process.

No change of gas mixture:

If you fail to conrm the change of gas
mixture or if you interrupt the switching
procedure by pressing the right button,
the Aladin Sport displays “GAS 1”/“GAS
2”, the MOD and the oxygen fraction for
5 seconds. The Aladin Sport continues to
calculate with gas 1/gas 2 only and adapts
the decompression calculation accordingly.

NOTE: After the decompression

F

calculation has readjusted itself to
reect a failed switch, if you once again
exceed the switch depth (MOD of gas
2/gas d) the Aladin Sport will revert to
the decompression calculation that
considers gas 2/gas d also, since
upon ascending again you will have
a renewed opportunity to perform
the switch once the switch depth is
reached.

Resetting the remaining saturation

WARNING

• Diving after a reset of the remaining
saturation may lead you into potentially
hazardous situations which could result in
death or serious injury. After a reset of the
remaining saturation do not dive for at least
48 hours.

• If you dive after resetting the remaining
saturation the computer will miscalculate
your decompression, which may result in
serious injury or death. Reset the remaining
saturation only if you know you will not be
diving, ying or going to higher altitude for
the next 48 hours.

• Resetting the desaturation should only
be done when there is a valid reason, e.g.
loaning the computer to somebody who has
not dived in 48 hours or more. When the
computer itself has remaining saturation
you must assume full responsibility for the
consequences of resetting the remaining
saturation.

7.2 Maintenance

The depth accuracy of your Aladin Sport
should be veried every 2 years and can be
done by an authorized SCUBAPRO dealer.
Aside from that, the Aladin Sport is virtually
maintenance-free. All you need to do is
rinse it carefully with fresh water after each
dive and change the battery when needed.
To avoid possible problems with your Aladin
Sport, the following recommendations will
help ensure years of trouble-free service:

• Avoid dropping or jarring your Aladin

Sport.

ALADIN SPORT USER MANUAL

• Do not expose your Aladin Sport to
intense, direct sunlight.

• Do not store your Aladin Sport in a
sealed container; always ensure that
there is ample ventilation.

• If there are problems with the water
contacts, use soapy water to clean your
Aladin Sport and dry it thoroughly. Do
not use silicone grease on the water
contacts!

• Do not clean your Aladin Sport with
liquids containing solvents.

• Check the battery capacity before each
dive.

• If the battery warning appears, replace
the battery.

• If any error message appears on the
display, take your Aladin Sport to an
authorized SCUBAPRO dealer.

7.2.1 Replacing the battery

(Use only the original SCUBAPRO battery
kit with O-ring.)

The change must be made with particular
care in order to prevent water from seeping
inside. The warranty does not cover
damage due to the improper replacement
of the battery.

WARNING

Never touch the metal surface of the battery
with bare ngers. The 2 battery poles must
never be short-circuited.

WARNING

• A leaking battery cap may lead to the
destruction of your Aladin Sport by water
seeping in, causing your Aladin Sport to
switch off without prior notice.

• Always open the battery compartment in a
dry and clean environment.

• Only open the battery compartment to
replace the battery.

English

Battery-changing procedure:

1. Dry your Aladin Sport with a soft towel.

2. Turn the battery cap with a coin or with
a SCUBAPRO universal tool.

3. Remove the battery cap.

4. Remove the O-ring carefully. Do not
damage the sealing surfaces.

5. Remove the battery. Do not touch the
contacts.

6. Always insert a new O-ring when
replacing the battery, and dispose of
the old O-ring. Make sure that the new
O-ring is in perfect condition, and that
the O-ring, the O-ring groove and the
sealing surfaces are free of dust and
dirt. If necessary, clean the parts with a
soft cloth. Fit the O-ring into the O-ring
groove of the battery cap.

WARNING

If you notice traces of seeping water, damage,
or other defects on the O-ring, do not use your
Aladin Sport for further dives. Take it to an
authorized SCUBAPRO dealer for inspection
and repair.

WARNING

7. Use only an original SCUBAPRO O-ring.
This O-ring is Teon-coated and does not
require additional lubrication.

8. Do not lubricate the O-ring as the lubricant
will chemically attack the battery cap.

WARNING

9. Before installing, check the proper polarity
of the battery. Your Aladin Sport can be
damaged if you do not insert the battery
correctly. Insert the new battery with the
“+” facing outwards. Once the battery is
replaced the Aladin Sport will perform an
automatic test (8secs) and a short beep
will sound when the test is done.

WARNING

10. The battery cap can be installed with a
±120° offset. Push the battery cap rmly
down and turn it clockwise until the 2
circles are aligned. The alignment circles
are there to ensure proper positioning of
the cap. If the rotation is stopped before
alignment, water-tightness may not be
ensured. If the rotation is forced beyond
the alignment, the cap may break. Damage
due to improper placement of the battery
cap is not covered by the warranty.

11. Check your Aladin Sport by switching it on.

12. Recalibrate the 3D compass. See chapter:
Compass, section: Recalibrating the
compass.

NOTE: Protect the environment and

ALADIN SPORT USER MANUAL

8.2 Glossary

AVG: Average depth, calculated from the beginning of the dive or from the time of reset.

CNS O2: Central Nervous System oxygen toxicity.

Desat: Desaturation time. The time needed for the body to completely eliminate any

nitrogen taken up during diving.

Dive time: The time spent below a depth of 0.8m/3ft.

Gas: Refers to the main gas that is set for the ZH-L16 ADT MB algorithm.

INT.: Surface interval. Elapsed time since your last dive ended.

Local time: The time in the local time zone.

Max depth: Maximum depth reached during the dive.

MB: Microbubble. Microbubbles are tiny bubbles that can build up in a diver’s body

during and after a dive.

MB level: One of the six steps, or levels, in SCUBAPRO’s customizable algorithm.

MOD: Maximum Operating Depth. This is the depth at which the partial pressure of

oxygen (ppO2) reaches the maximum allowed level (ppO2max). Diving deeper than
the MOD will expose the diver to unsafe ppO2 levels.

Multi-gas: Refers to a dive in which more than one breathing gas is used (air and/or nitrox).

Nitrox: A breathing mix made of oxygen and nitrogen, with the oxygen concentration

being 22% or higher. In this manual, air is considered as a particular type of
nitrox.

No Fly: Minimum amount of time a diver should wait before taking a plane.

No-stop time: This is the time that a diver can stay at the current depth and still make a direct

ascent to the surface without having to perform decompression stops.

O2: Oxygen.

%O2: Oxygen concentration used by the dive computer in all calculations.

PDIS: Prole Dependent Intermediate Stop is an additional deep stop, which is

suggested at the depth where the 5th..7th compartment starts off-gassing.

ppO2: Partial pressure of oxygen. This is the pressure of the oxygen in the breathing

mix. It is a function of depth and oxygen concentration. A ppO2 higher than

1.6bar is considered dangerous.

ppO2 max: The maximum allowed value for ppO2. Together with the oxygen concentration it

denes the MOD.

Press: The act of pressing and releasing one of the buttons.

Press-and-hold: The act of pressing and holding one of the buttons for 1 second before releasing it.

SOS mode: The result of having completed a dive without respecting all mandatory

decompression obligations.

Stopwatch: A stopwatch. To time certain steps of the dive.

UTC: Universal Time Coordinated. Refers to time zone changes when traveling.
