[. . . ] If you exceed that depth, the Depth, Max Depth, and Dive Log readouts will display dashes signifying that you descended out-of-range (Fig. For that dive, you will not see a numeric depth display over 250 feet (76 meters) or a Max Depth indication other than the three dashes. Although the PRODIGY will withstand the pressures found at 250 feet (76 meters), the depth that you can still use all its features can be much shallower. Before going further, read this warning: FT WARNING - The maximum recommended sport diving limit is 130 feet (40 meters). Special training and equipment are necessary for this type of diving. Oceanic strongly recommends against diving to depths below 130 feet (40 meters) or decompression diving. ® Fig. 22 ­ Out of Range display On a first "clean" dive, no residual nitrogen from previous dives, the PRODIGY will allow a maximum of 7 minutes no-decompression dive time available at 160 feet (48 meters). The PRODIGY will continue to calculate residual nitrogen for up to 24 hours. Depending on your descent rate, 7 minutes at 160 feet (48 meters) can be a very short amount of time. It is much more practical to stay within the 11 minutes of no-decompression time allowed at 130 feet (39 meters). If you exceed 160 feet (48 meters), watch the 28 PRODIGY closely because you will enter decompressionrapidly. Upon entering decompression the TLBG will enter the red zone and the decompression dive icons will be displayed (Fig. EMERGENCY DECOMPRESSION After entering decompression (especially at deeper depths) the TLBG may fill the 10, 20, 30, and 40 FT (3, 6, 9, and 12 M) STOP decompression zones rapidly. 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.
