[. . . ] Once you've entered decompression, it is imperative that you immediately begin an ascent at a safe rate of 60 feet (18 meters) per minute or slower toward the required decompression ceiling. If you continue to dive at a deeper depth, your exposure to decompression sickness will increase, and you risk entering a violation mode and losing information needed to properly ascend. Whether at 160 feet (48 meters) on a first dive, or 60 feet (18 meters) on a third dive, it is possible to quickly enter decompression if you're not careful. Decompression is to be avoided because you cannot ascend directly to the surface without potentially dire consequences. If your equipment failed, requiring you to surface immediately, you would risk decompression sickness. Your buddy would be unable to lend assistance without also risking decompression sickness. Decompression diving requires special training and equipment to be done properly. For these reasons, decompression sport diving should be avoided. FT ® Fig. 23 ­ Decompression warning 29 VIOLATION MODES If you exceed certain limits, the PRODIGY will not be able to tell you how to get back to the surface. These situations will make the PRODIGY enter violation mode and must be avoided at all costs. They push decompression theory to the limits and can result in loss of some PRODIGY functions for 24 hours after the last dive of a day in which a violation occurred. There are three different Violation Modes that the PRODIGY can enter depending on the situation. They are termed "Conditional Violation Mode, " "Delayed Violation Mode, " and "Immediate Violation Mode. " It is important to understand how each of these modes function and how to carry out decompression procedures in the event you encounter one. CONDITIONAL VIOLATION MODE Before a situation that may ultimately result in loss of nitrogen monitoring functions, the PRODIGY will enter a Conditional Violation Mode. If properly handled, the Conditional Violation Mode will not only assist you in getting back to the surface, but will also allow continued use of the PRODIGY. There is one situation that will force the PRODIGY to enter a Conditional Violation Mode: Ascending Shallower than Decompression Ceiling The PRODIGY will enter a Conditional Violation Mode if you ascend shallower than the decompression ceiling indicated by the TLBG (Fig. A mo- 30 mentary rise above the ceiling, such as with a surge or swell, will cause this to happen. Therefore you must stay slightly deeper than the exact ceiling depth, watching the PRODIGY closely when managing decompression. The PRODIGY will alert you to a Conditional Violation by flashing the Total Decompression Stop Time display until you descend below the required decompression ceiling. Once the PRODIGY enters a Conditional Violation Mode, no off-gassing credit will be given. For every minute in the Conditional Violation Mode, 1. 5 minutes of penalty time is added to decompression stop time for greater protection. The PRODIGY will stay in the Conditional Violation Mode for up to 5 minutes of being shallower than the decompression ceiling. [. . . ] WARNING ­ Oceanic recommends that you follow the rules of responsible diving on every dive, and strongly recommends against decompression diving, or diving below 130 feet (39 meters). CONCLUSION The PRODIGY will provide you with information to help plan your dives, make mid-dive decisions, and enjoy more fun time underwater. However, it is only an informational tool whose entire worth depends on using it correctly. The PRODIGY can greatly add to your enjoyment of the underwater world. [. . . ]
