1. Aladin® Pro - With More Safety The impressing operational features and its aspects of safety and quality make Aladin® Pro an outstanding diving computer. Building on the proven technique and finish the Aladin® Pro has now been made safer and more comfortable by incorporating a new, revolutionary calculation model. Aladin® Pro desplays all information necessary for safe diving in such a manner that it is easy to survey and to be understood at once.
2. Aladin® Pro - Your Personal Companion I Aladin® Pro considers your individual reactions during the dive, the cooling of your skin and includes your workload by a constant value in the calculations. 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 in the venous circulation depending on workload and skin temperature.
2. Aladin® Pro - Your Personal Companion WARNING WARNING Although the Aladin® Pro can be used to plan decompression dives, such dives are beyond the realm of recreational or sport diving and must not be attempted by recreational or sport scuba divers.
3. The Calculation Model ZH-L8 ADT I 3.1 Description The Aladin® Pro 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: The decrease in skin temperature is based upon the water temperature and the dive time.
3. The Calculation Model ZH-L8 ADT 2. The decompression model used by the Aladin® Pro 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 ® Pro 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.
3. The Calculation Model ZH-L8 ADT I If a diver experiences any of these risk factors while diving, the Aladin® Pro will decrease remaining bottom time without requiring decompression, or will add required decom-pression time in order to help minimize the risk of decompression sickness. 3.
4. Safety in Diving With its new decompression model the Aladin® Pro 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® Pro.

Beside this indicator is the time in hours that should pass before a flight.
5. Functions at the Surface 5.4 Warning of bubbles depth dive time DO NOT FLY h DESATURATION h max. depth deco info Through repetitive dives microbubbles may accumulate in the lungs if the surface interval is not long enough. Ignoring decompression stops or an excessive ascent rate can also lead to bubbles in tissues. In order to reduce the risk of decompression sickness for future repetitive dives, the surface interval should be planned long enough to reduce the risk of decompression sickness.
6. Diving in Mountain Lakes depth dive time DESATURATION h max. depth Aladin® Pro measures the atmospheric pressure even while in sleep-mode. If the computer detects a higher altitude, it switches into surface-mode automatically. Desaturation time indicated at this moment refers to adaptation time at this altitude. If diving starts within this adaptation time, Aladin® Pro treats it as a repetitive dive, since the body still has a higher saturation.
6. Diving in Mountain Lakes In order to assure optimal decompression even at higher altitudes, the 10 ft decompression stage is divided into a 13 ft stage and a 7 ft stage (the pescribed decompression depths are, in sequence, 7 ft, 13 ft, 20 ft, 30 ft). depth max. depth dive time deco info WARNING III Diving with Aladin® Pro Aladin® Pro can be used as decompression computer in case of an emergency up to an altitude of 13123 ft.

IV DIVING AT REDUCED RISK WITH ALADIN® PRO 1. Diving at Reduced Risk with Aladin® Pro 1.1 Diving at reduced risk __________________ 46 1.2 Minimizing risk on repetitive dives ________ 48 1.
1. Diving at Reduced Risk with Aladin® Pro 1.1 Diving at reduced risk Analyzing the most recent results of decompression research and statistical analysis of diving accidents involving decompression sickness allows for the creation of guidelines for diving at reduced risk for decompression sickness. Aladin® Pro recognizes and reacts “intelligently“ to certain risk situations. Of course, it is much better that each individual diver avoids these higher risk situations altogether.
1. Diving at Reduced Risk with Aladin® Pro • Always make the deepest dive of the day first when repetitive dives are planned, and for each successive dive make sure that the deepest portion of that dive is done at the beginning of the dive. • The Aladin® Pro is designed for dives made with compressed air only. Do not use the Aladin® Pro for dives made with nitrox or other mixed gases.
1. Diving at Reduced Risk with Aladin® Pro • You MUST be familiar with all signs and symptoms of decompression sickness before using the Aladin® Pro! Seek IMMEDIATE treatment for decompression sickness should any of these signs or symptoms occur after a dive! There is a direct correlation between the efficacy of treatment and the delay between the onset of symptoms and the treatment for decompression sickness. • Always observe the optical and acoustic alarm signals of the Aladin® Pro.
1. Diving at Reduced Risk with Aladin® Pro • Never make “square“ dive profiles of 60 feet or greater as repetitive dives. • Avoid yo-yo diving during repetitive dives. • Plan for a minimum surface interval of three to four hours. • Do not attempt to repetitive dive if the is visible on the display. IV • Take a day off from diving every three or four days. • Avoid exertion at depth and during the ascent. • Make sure you always have enough air for the ascent. 1.
1. Diving at Reduced Risk with Aladin® Pro Situation: The diver ascends too rapidly: Reaction of computer: The model calculates the formation of bubbles due to the excessively rapid ascent. No-stop time is shortened or a longer (and eventually at greater depth) decompression prescription is displayed in order to assure increased decompression. Recommended response of the diver During the dive: – Observe the new decompression prescription shown by Aladin® Pro.
1. Diving at Reduced Risk with Aladin® Pro Situation: The diver disregards the prescribed decompression depth. Reaction of computer: The model calculates the formation of bubbles due to ignoring decompression. A longer (and eventually at greater depth) decompression is displayed in order to assure sufficient time for desaturation. Recommended response of the diver During the dive: – Descend to the prescribed decompression depth at once. – Do not descend to greater depths during the dive.
1. Diving at Reduced Risk with Aladin® Pro Situation: The diver is physically exerting himself or herself, (e.g. swimming against the current). Recommended response of the diver During the dive: – Avoid further physical exertion if possible. Relax. – Extend decompression time at the highest stop if possible. After the dive: 52 – Refrain from heightened physical exertion on your next dive. – Make sure the surface interval is long enough. It may be advisable to go on another dive only the next day.
1. Diving at Reduced Risk with Aladin® Pro Situation: It is very unlikely to have a surface interval long enough to clear the prior to the next dive during an organized dive trip from a boat. This previous buildup of nitrogen must be taken into consideration for the next dive. Reaction of computer: Aladin® Pro calculates a shorter no-stop time or decompression prescription to reduce the risk of decompression sickness.

VIII TROUBLE SHOOTING 1.
1. Trouble Shooting symptom possible reason(s) response Altitude section does not correspond to the current altitude. Atmospheric pressure is especially high or low. Air pressure measured by the computer is wrong. Check barometric information. Desaturation time and/or no fly time are very long. Slow tissue and/or little workload at the surface. Review chapter III 5 very carefully. Too many repetitive dives, yo-yo-diving, square profile repetitive dives or disregarding decompression stops.
1. Trouble Shooting symptom possible reason(s) response An unexpected decompression stop appears in place of no-stop time or decompression increases in leaps. Too rapid an ascent or ignoring decompression stops have caused a large number of microbubbles, which leads to an attention message (warning of bubbles). Plan sufficiently long surface interval and dives at lower risk. Review chapters III 5 and IV very carefully. Attention messages are not given acoustically.
