Safety considerations
Uwatec®Aladin®Sport Plus
You must carefully read and understand this entire manual before using your Aladin®Sport Plus.
Diving has many inherent risks. Decompression sickness is among the most
serious of those risks. Even if you follow the instructions of this manual in a
careful manner, it is still possible that you may be seriously injured or die from
decompression sickness or some other inherent risk of scuba diving. Unless
you are fully aware of these risks and are willing to personally accept and
assume responsibility for those risks, do not use the Aladin
®
Sport Plus!
The Aladin®Sport Plus is a sophisticated dive computer to assist a trained and certified diver in making
decisions concerning dive planning and execution. As with any tool, the Aladin
®
Sport Plus may be misused if the following safety and operational precautions are not strictly followed. If they are followed,
careful use of the Aladin®Sport Plus can increase your diving enjoyment and reduce your risk of decompression sickness. If they are not, you will be placing yourself at serious risk for decompression sickness.
While the Aladin
®
Sport Plus is a technically advanced tool based on a mathematical model of decompression sickness, neither it nor any other diving computer (or table) can exactly monitor the physiological
changes that occur in your body as you dive. In addition, each diver will vary in his or her susceptibility to
decompression sickness. In addition to this, each individual diver‘s own susceptibility may vary from day to
day. Combined with the fact that decompression modelling is an inexact science, and must be based to
some extend on certain unproven assumptions, it is emphasis on you, the individual diver, to dive responsibly and to carefully follow all standard safe diving practices as well as the recommendations contained
in this manual.
Guidelines for the use of Aladin
®
Sport Plus:
The following guidelines for using Aladin®Sport Plus are derived from the latest medical research and the
recommendations of the American Academy of Underwater Sciences for diving with diving computers.
Following these guidelines will greatly increase your safety while diving, but cannot guarantee that decompression sickness will not occur.
– The Aladin
®
Sport Plus is designed for dives made with compressed air only. Do not use the Aladin® Sport
Plus for dives made with nitrox or other mixed gases.
– In accordance with the recommended maximum diving limit of all instructional agencies, do not dive
deeper than 130 feet. The danger of nitrogen narcosis has to be taken into consideration. The Aladin

Safety considerations
Uwatec®Aladin®Sport Plus
American
Sport Plus gives no warning about this.
– On all dives with the Aladin®Sport Plus, make a safety stop for at least 1 to 3 minutes within the 10 to
15 feet zone.
– Always make the deepest dive of the day first when repetitive dives are planned, and for each dive make
sure that the deepest portion of that dive is done at the beginning of the dive.
– All divers using dive computers to plan dives and indicate or determine decompression status must use
their own computer which they take with them on all dives.
– If the Aladin
®
Sport Plus fails at any time during the dive, the dive must be terminated, and appropriate surfacing procedures (including a slow ascent and a 3 to 5 minute safety stop) should be initiated
immediately.
– On any given dive, all divers in a buddy group must follow the most conservative dive computer for that
particular dive.
– Repetitive dives after exchanging the dive computer: Wait at least 24 hour before you start with the
repetitive dive.
– Always observe the optical alarm signals of the Aladin
®
Sport Plus. Avoid situations of increased risk for
decompression sickness which are marked with a warning sign in this operating manual.
– The decompression algorithm contained in the Aladin
®
Sport Plus only serves for emergency or unin-
tended decompression.
– Never use the Aladin® Sport Plus for repetitive, “square“ dives deeper than 60 feet. A square dive is a
dive that is performed for its duration at a uniform depth.
– You MUST follow the ascent rates as indicated by the Aladin
®
Sport Plus, and should the computer fail
for any reason, you must ascend at a rate of no greater than 30 feet per minute.
– You MUST be familiar with all signs and symptoms of decompression sickness before using the Aladin
®
Sport Plus! Seek IMMEDIATE treatment for decompression sickness should any of these signs or symptoms occur after a dive! There is a direct correlation between the effectiveness of treatment and the
delay between the onset of symptoms and the treatment for decompression sickness.
– Never dive the Aladin® Sport Plus to the limits. Neither the Aladin® Sport Plus, nor any other diving com-
puter or decompression table should be pushed to its limit. Give yourself a margin of safety by always
leaving at least a few minutes in the “no-stop“ box before making your ascent.
– Avoid repeated ascents and descents (yo-yo diving) while using the Aladin
®
Sport Plus.

1 Aladin®Sport Plus - Safe No-Stop Diving
The proven no-stop dive computer Aladin is furnished with a new, revolutionary calculation model which
makes it even safer and more comfortable. The Aladin®Sport Plus is designed for no-stop diving, but also
provides the necessary information for safe diving in case of a decompression dive. Aladin®Sport Plus displays all information necessary for safe diving in such a manner that it is easy to survey and to be understood at once.
The convincingly simple handling and the high comfort of carrying speak for themselves from the first dive.
Read this operating manual carefully and to the last page.
2 Aladin®Sport Plus Your Personal Companion
Aladin®Sport Plus considers your individual reactions during the dive and the cooling of your skin.
The latest results of medical and technical research were taken into consideration. As a special feature the
calculation model also considers the formation of micro-bubbles and the skin temperature. This has led
to the development of a unique, adaptive calculation model.
Aladin
®
Sport Plus was exclusively designed for diving with compressed air and especially for diving in the
no-stop range. It distinguishes itself from its 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 con-
duct and the ambient conditions. This allows for an even more precise calculation of a modeled risk for
decompression sickness which can lead to greater diving safety.
• The Aladin
®
Sport Plus is much more of a personal instrument, which considers the individual conduct
of the diver.
Different conducts of diving buddies can lead to distinctive differences in the display of the no-stop and
decompression information, since risk situations (violations of the diving rules) may have a strong influence by the anticipation of physiological processes. On the other hand, Aladin
®
Sport Plus “rewards” a
diving conduct following the rules with highest diving comfort.
• The new calculation model considers for the calculation of the surface intervals and the decompression
information for repetitive dives that the physical performance at the surface is smaller than during the
dive.

• The Aladin®Sport Plus uses optical alarms in risk situations or dangerous conduct.
You must strictly observe all optical alarms due to risk situations or dangerous
conduct and take appropriate action based upon those alarms to avoid
serious injury or death from decompression sickness!
• By using the Aladin
®
Sport Plus‘s logbook, a diver may directly call up information from the last 19 dives.
When interfaced with a personal computer, 37 dives and 200 minutes of dive profile in intervals of 20
seconds can be read out.
• The dive planner allows the advance planning of no stop dives with readily determinable surface intervals.
• Aladin
®
Sport Plus is designed to be carried on the diver‘s wrist. Ease handling, easy to watch and unambiguous arrangement of the data in the display, increase of diving safety without the loss of diving comfort and the possibility of transferring data to a personal computer are the main features of the Aladin
®
Sport Plus comfort.

3 The Calculation Model ZH-L8 ADT
I Uwatec®Aladin®Sport Plus
3.1 Description
The Aladin
®
Sport Plus uses a new decompression calculation model known as the ZH-L8 ADT. This model
uses eight compartments or “tissue“ groups with nominal half time periods from 5 to 640 minutes. This
model differs considerably from other models by its consideration of the following additional physiological
processes:
1. Blood perfusion to the body‘s organs is not constant. Skin and muscle tissues are especially subject to
changes in blood perfusion, depending on temperature and work load. Changes in blood perfusion to
these organs change their nitrogen saturation tolerance. The model used by the Aladin
®
Sport Plus takes
these effects into account and thus the “skin“ and “muscle“ compartments in the Aladin®Sport Plus
show variable half-time periods and saturation tolerances. Decompression information is calculated
according to the workload and decrease in skin temperature. The decrease in skin temperature is based
upon the water temperature and the dive time. By considering these changes in saturation, the time
that must be spent at the surface prior to flying can be considerably lengthened, depending upon the
depth, time, and temperature of a dive, as well as the diver‘s work during that dive.
2. The decompression model used by the Aladin
®
Sport Plus considers nitrogen in both its dissolved as well
as its gaseous phase (microbubbles). Formation of microbubbles is considered to be a strong indicator
of a high risk of decompression sickness. The Aladin®Sport Plus model calculates the formation of
microbubbels depending on various assumed influences in arterial and venous blood. In normal, slow
ascents, microbubbles form mainly in venous blood. During fast ascents, microbubbles may also form in
arterial blood and in the body‘s tissues as well. If a particular dive profile may result in the creation of
microbubbles according to the Aladin
®
Sport Plus‘s model, decreased bottom time and/or increased
decompression times as well as increased “no fly“ time will be indicated.
• Microbubbles can form if the diver makes too fast an ascent, ignores required decompression stops, or
makes repeated ascents during a dive (yo-yo diving). These microbubbles can form in arterial blood as
well as in the body‘s tissues. If these microbubbles partially impair circulation, the rate of gas diffusion
and saturation tolerance for those tissues immediately surrounding this area of impaired circulation are
changed. If required, no-stop time, decompression time and -depth will be adjusted in such a way that
already existing microbubbles will stop growing. Increased decompression time will also assist those local
areas of impaired circulation to desaturate with less risk of decompression sickness.
13
3 The Calculation Model ZH-L8 ADT
I Uwatec®Aladin®Sport Plus

• The calculation of microbubbles results in altered ascent instructions. If microbubbles are assumed to be
present based on the data used by the Aladin®Sport Plus, the ascent rate to the surface is reduced to
23 feet/minute. This will help prevent the formation of microbubbles in the arterial circulation and minimizes formation of microbubbles in the venous circulation after the dive.
3.2 Advantages
On the first dives following responsible diving procedures, a diver using the Aladin
®
Sport Plus should
never experience a shortened no-stop phase or be required to decompress, although at least a 1 to 3
minute safety stop between 10 and 15 feet is recommended for every dive. If, however, unplanned circumstances arise during the dive which increase the risk of decompression, the Aladin
®
Sport Plus can, if
closely followed, reduce the risk of decompression sickness by increasing decompression time. Some of
the more common risk situations are as follows:
• Repetitive dives, especially those deeper than 60 feet and those with short surface intervals.
• Repetitive dives using square dive profiles.
• Repetitive diving over the course of several successive days.
• Diving in cold water.
• Yo-yo diving (repeated descents and ascents to the surface during a given dive).
• Flying within 24 hours after diving.
• Excessive ascent rate.
If a diver experiences any of these risk factors while diving, the Aladin
®
Sport Plus will require decom-
pression in order to help minimize the risk of decompression sickness.
Do not use the Aladin
®
Sport Plus for planned decompression dives!

4 Safety in Diving
I Uwatec®Aladin®Sport Plus
If signs or symptoms of decompression sickness occur after diving with Aladin®Sport Plus, seek IMMEDIATE treatment at the nearest recompression facility.
With its new calculation model the Aladin
®
Sport Plus is an extremely versatile tool which can increase your
diving comfort and safety. As with any diving tool, however, ultimate responsibility for diving safety
remains with the individual diver. The same responsible diving practices taught by all diving certification
agencies are still absolutely necessary in order to safely dive with the Aladin
®
Sport Plus.
Certain mistakes which may be made by a diver, such as ascending at an excessive rate, going too deep,
or staying too long at depth, may be overcome if the diver carefully follows the Aladin
®
Sport Plus‘s corrected ascent instructions. Of course, the Aladin®Sport Plus can do nothing to prevent the occurrence of
lung overexpansion injuries or nitrogen narcosis, whose avoidance lies solely with the individual diver. The
Aladin®Sport Plus is a highly sophisticated technical instrument which, if used and maintained properly,
will have high reliability. Despite that, no dive should be made with an Aladin®Sport Plus without a
thorough understanding of decompression theory and dive table use, and every diver must have a set of
decompression tables with him on every dive.
Do not use the Aladin
®
Sport Plus without a set of accepted diving tables
with you as a back up decompression tool on every dive.
Should decompression sickness occur, whether the Aladin
®
Sport Plus was used correctly or not, a detailed history of the previous dives may be used to allow a better diagnosis and the most effective treatment
for the diver.
