2I Introduction
The proven no-stop dive computer Aladin is
enhanced with a new, revolutionary calculation
model which makes it even safer and more
comfortable. The Aladin of the new generation is
called Aladin®Sport and is part of the Aladin
family which also includes the air
integrated Aladin®Air X and
the decompression computer
Aladin®Pro.
Although the Aladin®Sport is designed for no-
stop diving it does provide the minimum necessary
information in the event of a diverequiring de-
compression stops.
The new generation Ala-
din®Sport provides an
increased level of safety
and more features to-
gether with it‘s tradi-
tional ease of use.
Read this operating manual carefully and to
the last page!

I Introduction
I
Aladin®Sport considers your individual reactions
during the dive, the cooling of your skin and includes
your workload as a constant value in the calculations.
The test results of medical and physiological research
were taken into consideration. The new calculation
model also predicts and considers the effects of the
formation of micro-bubbles in both the venous and
arterial circulation depending on workload and skin
temperature. This has led to the development of a
unique, adaptive calculation model.
Aladin®Sport was exclusively designed for diving
with compressed air and distinguishes itself from
previous models and other commercial diving
computers in a number of significant ways.
• The ZH-L8 ADT decompression calculation model
considers eight body tissues as well as the diver's
conduct and the ambient conditions. This allows for an
even more precise calculation of the risk for
decompression sickness which increases diver safety.
.• Compared to all previous models the Aladin®Sport
is much more of a personal instrument, as it
considers the individual conduct of the diver.
Different actions by diving buddies can lead to
distinctive differences in the display of the decom-
pression information. This is because risk situations
(violations of diving rules) can have a significant
effect on the physiological processes. On the
other hand Aladin®Sport ‘rewards’ a diving
conduct.
• The diver's workload is incorporated in the decom-
pression calculations as a constant value. For the
calculation of the surface intervals and the
decompression information for repetitive dives the
new model calculates on the basis that the
physical performance at the surface is smaller than
during the dive.
• Alarms are given optically in risk situations or in
case of dangerous conduct.

4I Introduction
2 Aladin®Sport – Your Personal Companion
• By means of the logbook, the diver can directl call
up the information of the last 19 dives
Via interface to the PC, 37 dives and 200
minutes of precise dive-profile in
intervals of 20 seconds can be
read out.
• The dive planner allows the
advance planning of no-stop
dives with freely determinable
surface intervals.
• Aladin®Sport is designed to be
mounted on the diver‘s wrist or built in
consoles.
• Ease of operation, ease of understanding
the unambiguous display, enhanced safety
advice, the PC interface option and comfort in use
are all strong features of the new Aladin®Sport.

3 Calculation Model ZH-L8 ADT
3.1 Description
The Model ZH-L8 ADT (8 compartments with nomi-
nal half-time periods from 5 to 640 minutes) differs
considerably from other models by the consideration
of additional physiological processes:
1. Blood perfusion of the organs is not constant.
Skin and muscles in particular are subject to
considerable changes of blood perfusion
depending on temperature and workload. A
change in blood perfusion also causes a change
of the saturation tolerance. The model takes
these effects into account. Therefore, skin and
muscle compartments show variable half-time
periods and saturation tolerances.
The necessary decompression times are calculated
according to the workload and the decreasing
skin temperature. The decrease of skin
temperature is estimated based on the water
temperature and the dive time. At the surface,
the diver’s physical performance is lower than
during the dive. By considering the differences in
physical performance the no fly time becomes
considerably longer.
2. The model considers inert gas not only in the
dissolved state, but also in the gaseous phase
(microbubbles). Formation of microbubbles is
calculated with allowance for the different
influences in arterial and venous blood. With nor-
mal ascents gas bubbles mainly form in venous
blood, with fast ascents also in arterial blood and
on ignoring decompression stops in the tissues.
As the model calculates microbubbles, those
physiological processes are reconstructed which
actually occur.
The bubbles on the venous side of the circulation
are carried into the lungs where they change the
arterial nitrogen pressure. This influences mainly
repetitive dives, dives with very long
decompression times and the no fly time.

6I Introduction
3 Calculation Model ZH-L8 ADT
• Gross disregard of the ascent rate, exceeding the
decompression depth and repeated ascents to the
surface (yoyo dives), can all cause microbubbles to
form on the arterial side and in tissues. Where the
bubbles partially impair circulation, the rate of gas
diffusion and the saturation tolerance are
changed. No-stop-time, decompression time, and
if necessary decompression depth, are adjusted so
that existing bubbles stop growing. In addition,
altered decompression assures that the tissue
desaturates sufficiently if microbubbles impair
circulation locally.
• The calculation of the gas bubbles results in a new
ascent instruction. The ascent rate near the
surface is reduced down to 7m/min. This prevents
with high reliability the formation of
microbubbles in the arterial circulation and
minimizes the formation of microbubbles in the
venous circulation after the dive.
3.2 Advantages
On first dives with correct diving technique and
avoiding risk situations, there are no extended
decompression times. On the other hand, it is
possible to react correctly in risk situations due to the
realistic simulation of the physiological processes in
the body. This increases safety considerably. Risk
situations are, for example:
• Repetitive dives (especially with short intervals)
and dives on several successive days
• Dives in cold water
• Yoyo dives
• Flying after the dive

I Introduction
I
In case of mistakes on the part of the diver, actual
prevention of decompression sickness is possible for
the first time due to the reconstruction of the bubble
formation and its consequences. The correction of
the decompression must not be confused with a real
recompression, which serves as therapy of already
existing damage.

8I Introduction
4 Safety in Diving
Should an incident occur, the detailed previous
history of the incident is stored in the dive computer.
The evaluation of these records allows better
diagnosis and the most effective treatment for the
diver.
With its new decompression model Aladin®Sport
offers a so far unreached level of safety. However,
responsibility for the dive finally remains with the
diver as before. The usual diving caution is still
absolutely necessary when diving with Aladin®Sport.
In case of diver mistakes (ignoring decompression
stops, excessive ascent rate etc.) Aladin®Sport can
calculate a corrected ascent instruction immediately
which minimizes the occurrence of decompression
sickness. The prevention of barotrauma and nitrogen
narcosis still lies in the hands of the diver.
Aladin®Sport is a highly developed technical instru-
ment of high reliability. Despite this, the user of the
Aladin®Sport is to have an understanding of the
physiological interrelations, to know the use of
decompression tables and to have them with him on
every dive.

pressure is necessary.
– manually by operating contacts on housing.
Switching off display: – automatically, after three minutes without operation.
Aladin®Sport has 4 operating contacts B, E, +, – on the outside of the housing. For manual operation touch
base contact B and any one of the other three contacts above the display with moistened fingers.
Contact B: Base contact, which has to be touched for all
operations
Contact E: Enter contact. It serves to switch on the computer, to
activate the logbook and dive-plan-mode and to
switch between no-stop and decompression
planning. It is also used to confirm inputs and is
therefore comparable to the ENTER- or RETURN-key
of a computer.
+ / –contacts: They serve to select the logbook and dive-plan as well
as to set values (time, depth, dive-number etc.).
