    (level stop) sooner than a diver using level L0. If a diver ignores a required level stop, Aladin TEC 3H will cascade to a lower MB level and the dive can not be completed with the initially chosen MB level. E.g. if a diver sets level L4 on Aladin TEC 3H prior to the dive and during the dive ignores the recommended stops Aladin TEC 3H will automatically adjust the setting to level L3 or lower.

    4.8.1 Comparison of dives with MB level L0 and MB level L5 When two Aladin TEC 3H are used simultaneously, one unit is set for example to MB level L5, the other to L0, the no-stop time will be shortened and level stops will be required before the diver has the obligation of a decompression stop.

    The warning “MB level reduced” is activated if the diver ascends more than 1.5m (5ft) above the required level stop. Aladin TEC 3H reduces the MB level, an attention beep* goes off and the new MB level is shown in the lower left corner.

WARNING Avoid decompression dives when diving with MB levels. How to avoid decompression stops:...

  • Page 40: Complete A Dive With Mb Levels

    Repetitive dives and MB levels: If during a dive a level stop is being ignored and the diver starts another descent shortly afterwards, Aladin TEC 3H might immediately request level stops. To complete the dive with the initially set MB level all level stops must be observed.

  • Page 41: Pdis (Profile Dependent Intermediate Stop)

    Spending 2 or 15 minutes at 30m/100ft would result in the same deep stop of 15m/50ft. With PDIS, as the name suggests, Aladin TEC 3H interprets your dive profile 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 reflect the continuosly changing situation in your body.

  • Page 42: How Does Pdis Work

    PDIS (Profile Dependent Intermediate Stop) 4.9.2 How does PDIS work? The mathematical decompression model in Aladin TEC 3H, called ZH-L8 ADT MB, tracks your decompression status by dividing your body into 8 so-called 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.

  • Page 43: Diving With Pdis

    NO to indicate the fact that you have not performed the PDI stop. If Aladin TEC 3H 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.
  • Page 44 PDIS (Profile Dependent Intermediate Stop) NOTE: Aladin TEC 3H issues no 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.

  • Page 45: Diving With 2 Or 3 Gas Mixtures

    Aladin TEC 3H enables you to use up to 3 different Nitrox mixtures during the same dive. Tank 1 contains the bottom mix (gas 1), tank 2 the travel mix and tank d contains the deco mix (gas d).

  • Page 51 If after the decompression calculation has readjusted itself to reflect the failed switch the diver goes again below the switch depth (MOD of gas 2 / gas d), Aladin TEC 3H will revert to the decompression calculation that considers gas 2 / gas d also, since upon ascending again the diver will have a renewed opportunity to perform the switch once the switch depth is reached.
