DECOMPRESSION MODEL The programs within the PRODIGY simulate the absorption of nitrogen into the body by using a mathematical model. This model is not magic, merely a way to apply a limited set of data to a large range of experiences. The PRODIGY dive computer model is based upon the latest research and experiments in decompression theory. Still, using the PRODIGY, just as using the U.S. Navy (or other) No-decompression Tables, is no guarantee of avoiding decompression sickness, i.e. "the bends." Every diver's physiology is different, it even varies from day to day. No machine can predict how your body will react to a particular dive profile. The PRODIGY is intended for use by divers who have successfully completed a nationally recognized course in scuba diving. It must not be used by untrained persons who may not have knowledge of the potential risks and hazards of scuba diving. You must obtain proper training before using the PRODIGY if you have not already done so. You also must read this owner's guide completely before diving with the PRODIGY. R5 R5 iii CONTENTS I.

INTRODUCTION The PRODIGY was designed to be extremely easy to use and understand. This owner's guide is divided into five sections designed to make it easy to learn how to use the PRODIGY. The first two sections will show you how it performs in most diving situations. Section three describes extreme condition performance such as deep or decompression diving. Sections four and five present care & maintenance procedures and reference material. Start here to begin learning about the PRODIGY. REGULATOR ATTACHMENT If you have purchased the PRODIGY in a console version, you will need to have it attached to your regulator by an Authorized Oceanic Dealer. ACTIVATING THE DISPLAY You can activate the PRODIGY by pressing and releasing the button under its display (Fig. 1a). After a diagnostic check (10 seconds), it enters "Surface Mode" signified by the Surface Display Icon (Fig. 1b). WARNING - Be sure to inspect your PRODIGY prior to every dive, checking for any signs of the entrance of moisture, damage to the button membrane, or damage to the LCD display. If these or other signs of damage are found, return the unit to an Authorized Oceanic Dealer or Oceanic Parts & Service. DO NOT attempt to use until it has received factory service. ® a. Fig. 1 ­ Surface Mode 2 PLANNING YOUR DIVE Surface mode shows the Surface Display Icon, the number of the most recent dive you have made, surface interval, and residual nitrogen. After 20 seconds, then once every minute, it alternates with another mode called the "Pre Dive Planning Sequence" (Fig. 2) signified by the Pre Dive Planning Identification Icon (Fig. 2a). When planning your next dive, the Pre Dive Planning Sequence (PDPS) provides adjusted no-decompression limits based upon previous dives made. The PDPS shows depths from 30 to 160 feet (9 to 48 meters) in 10 foot (3 meter) intervals and the available no-decompression time for each. This makes dive planning extremely simple because you know exactly how much time you can spend at each depth without making any table calculations. MAKING A DIVE Once you enter the water and descend to a depth below 5 feet (1.5 meters), the PRODIGY changes to the "No-decompression Dive Mode" (Fig. 3) signified by the No Decompression Identification Icon (Fig. 3a). This mode displays current depth, elapsed dive time (and Elapsed Dive Time Icon), nodecompression time remaining, maximum depth for this dive (and Max Depth Icon), nitrogen loading (and Tissue Loading Bar Graph) and ascent rate (and Variable Ascent Rate Indicator). a. FT ® Fig. 2 ­ Pre Dive Planning Sequence 3 d. b. FT USING THE "GRAPHIC DIVER INTERFACE" To make it easy to check your dive status on the PRODIGY, a color-coded system of graphic displays is used. This "Graphic Diver Interface" is made up of two bar graphs that have green, yellow and red markers to indicate normal, caution, and danger zones, respectively. The two graphic displays represent ascent rate and nitrogen loading. When underwater, you can make quick status checks by glancing at the two bar graphs and making sure that they are "in the green." With one quick glance you can make sure you're not getting too close to the no-decompression limit or ascending too fast. ASCENDING TO THE SURFACE A graphic representation of nitrogen absorption can be seen in the "Tissue Loading Bar Graph" (Fig 3b). This green, yellow, red bar graph shows how close you are to the no-decompression limit. It "fills­up" with segments as your depth and bottom time increase, simulating the absorption of nitrogen. Upon ascent to shallower depths, the Tissue Loading Bar Graph (TLBG) will begin to recede giving a visual representation of nitrogen off­ gassing. The TLBG also provides a way to easily manage decompression by indicating four red "ceiling" depths. This is discussed fully in the "Handling the Extremes" section beginning on page 27. a. ® c. Fig. 3 ­ No-decompression Dive Mode 4 When rising towards the surface, the "Variable Ascent Rate IndicatorTM" (Fig. 3c) shows how fast you are ascending. The Variable Ascent Rate Indicator (VARI) will alert you with a flashing display if you enter the red zone, which represents ascent rates over 60 feet (18 meters) per minute. Immediately slow your ascent whenever this is seen. If you have not entered decompression, a safety stop made between 15-20 feet (4.5-6 meters) is strongly recommended as a standard procedure before completing your ascent. Many divers do this to provide a wider zone of caution from the no-decompression limit. The TLBG gives a visual representation of just how close you are to the no-decompression limit with a yellow "Caution Zone" (Fig. 3d). This Caution Zone portion of the TLBG allows you to make a decision regarding safety stop duration or necessity. While you cannot provide a guarantee against the occurrence of decompression sickness, you may choose your own personal zone of caution based on age, physique, excessive weight, etc., to reduce the statistical risk. EMERGENCY DECOMPRESSION If your depth or bottom time is such that the TLBG enters the red zone, the PRODIGY will switch to the "Decompression Dive Mode" (Fig. 4) signified with the flashing Decompression Dive Identification Icon (Fig. 4a). A decompression stop "ceiling" will be indicated by the TLBG (Fig. 4b), digital display (Fig. 4c), and Stop Ceiling Icon (Fig. 4f). You must stay below the a. b. FT e. c. ® d. f. Fig. 4 ­ Decompression Dive Mode 5 ceiling depth indicated or risk decompression sickness. Also indicated by digital displays are current depth, decompression time for current stop (Fig. 4d) and total decompression stop time (Fig. 4e). You must stay at or a few feet below the TLBG indicated ceiling depth until the bar graph recedes into the next shallower zone before ascending any further. An alternate display (Fig. 5) appears automatically for 3 seconds at 12 second intervals during a decompression dive. The display replaces individual stop information with maximum depth (and Max Depth Icon, Fig.5a) and elapsed dive time (and Elapsed Dive Time Icon, Fig. 5b). FT a. ® b. PLANNING FOR THE NEXT DIVE After reaching three feet upon ascent, the Surface Mode will display once again. After 10 minutes, and at one minute intervals, it alternates with the Pre Dive Planning Sequence. The Pre Dive Planning Sequence will show adjusted no-decompression limits based on the nitrogen absorbed during your last dive. The longer the surface interval, the more dive time available in the PDPS. Fig. 5 ­ Decompression Dive Mode-Alternate 6 IT'S REALLY JUST THAT SIMPLE! The PRODIGY is designed to help you stay out of trouble with quick visual reference during all modes of operation. Just "keep it in the green" and you'll greatly reduce your exposure to decompression sickness. WARNING ­ Using the PRODIGY, just as using the U.S. Navy (or other) No-decompression Tables, is no guarantee of avoiding decompression sickness, i.e. "the bends." a. OTHER SPECIAL FEATURES The PRODIGY also helps you log your dives, dive at high altitudes, and know when the minimum allowable surface time has elapsed to be able to fly, according to UHMS guidelines. These special features are described on the following pages. ® LOGGING YOUR DIVES Immediately after a dive, various information is stored in the PRODIGY's memory and can be accessed in the "Dive Log Mode." Recalling this information gives you a chance to record it in your log book. Your latest 10 dives are stored and can be accessed by pressing the activation button. Dive Log Mode signified by the Dive Log Identification Icon (Fig. 6a) will automatically scroll through the latest ten dives starting with the most Fig. 6 ­ Dive Log Mode 7 recent dive first. The log displays dive number, surface interval, maximum depth (and Max Depth Icon), bottom time (and Elapsed Time Icon), and maximum ascent rate (VARI). It also displays end­of­dive tissue loading (TLBG). This is handy when making decisions about future dive plans. ALTITUDE DIVING The PRODIGY automatically compensates for decreased ambient pressure when activated at high altitudes up to 14,000 feet (4,268 meters). Its program contains a high altitude algorithm that reduces no-decompression limits to add a larger zone of caution. Whenever it is activated above 3,000 feet (915 meters), it will automatically recalibrate itself to measure depth in feet of fresh water. KNOWING WHEN TO FLY Due to the present lack of a complete data set derived from actual human testing, there ar ...
