No, the Oceanic Prodigy does not allow switching between metric and imperial settings. It is manufactured as either metric or imperial, and the unit type cannot be changed.

  • Page 6: 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.
  • Page 7 ® 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), no- Fig.
  • Page 8 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 nor- mal, caution, and danger zones, respectively.
  • Page 9 If your depth or bottom time is such that the TLBG enters the red zone, Fig. 4 – Decompression the PRODIGY will switch to the “Decompression Dive Mode” (Fig. 4) signi- Dive Mode fied with the flashing Decompression Dive Identification Icon (Fig. 4a). A decompression stop “ceiling”...
  • Page 10 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.
  • Page 11 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.
  • Page 12 The PRODIGY follows one of the more conservative of these, cited by Divers Alert Network (DAN); that divers wait at least 12 hours before flying in pressurized commercial aircraft, and at least 24 or more if making repeti- tive multi-day or decompression dives.
  • Page 13 Planning Sequence over again. After the timer reaches zero, 24 hours have elapsed. You may choose when to fly according to the type of diving you have done, consulting your PRODIGY to determine the amount of surface time that has elapsed. To learn more about flying after diving and DAN's guidelines, see page 24.

    15% of rated voltage all graphic displays will shut off except the Bat- ® tery Icon which will flash 15 final times prior to shutdown of the PRODIGY. WARNING - Never activate the PRODIGY if the computer is under- water.
  • Page 17 WARNING - If a Low Battery condition is indicated immediately upon activation, Oceanic strongly recommends that you DO NOT dive until you have obtained battery replacement, described on pages 47-50. Activating the External Access(EA) mode, described...
  • Page 18 profiles. The PDPS automatically replaces Surface Mode every minute. Information provided includes depths and no-decompression dive times. WARNING – The Pre Dive Planning Sequence predicts only no- decompression times for subsequent dives. Depending on tank size and air consumption, you may have less time available than shown in the PDPS because of air limitations.
  • Page 19 DECOMPRESSION DIVE MODE The PRODIGY will help you to avoid, or easily manage, decompression. Before explaining further, read the following warning. WARNING - Oceanic recommends the application of responsible diving practices and does not recommend decompression diving, or diving deeper than 130 feet, as these practices will greatly increase your risk of decompression sickness.
  • Page 20 Still, you must never ascend shallower than your decompression ceiling! Doing so will place the PRODIGY into a Conditional Violation Mode (see page 30) and greatly increase your risk of decompression sickness. Often while coping with surge and swell, it is difficult to stay at a chosen depth.
  • Page 21 Gauge Mode on subsequent dives. The PRODIGY removes displays that no longer provide correct information because of the violation (see page 35). No dives must be made for 24 hours for the PRODIGY to reset itself. DIVE LOG MODE Dive Log Mode, identified by the Dive Log Icon (Fig.
  • Page 22 When accessing Dive Log Mode, you can choose to either press and release, or press and hold, the button on the face of the PRODIGY. As mentioned, pressing and releasing the button initiates the Automatic Dive Log Sequence, showing previous dives for about four seconds each.
  • Page 23 TELLING THE DIFFERENT MODES APART The PRODIGY’s different operating modes are easy to tell apart. Each is clearly identified with graphic Mode Icons (Fig. 16) which provide quick visual reference during the various modes of operation. You will not see Decompression Dive, Violation, or Gauge Modes unless you dive to extremes.

  • Page 24: Informational Displays

    INFORMATIONAL DISPLAYS Each PRODIGY numeric or graphic display represents a unique piece of information. The following section describes each display in detail. Depth Display The top portion of the LCD (Fig. 17a) contains the current Depth display. The dive number display replaces the depth display in the Surface or Dive Log modes.
  • Page 25 GRAPHIC DIVER INTERFACE Two different bar graphs are located around the perimeter of the PRODIGY LCD (Fig. 18). They are color coded green, yellow, and red to denote normal, caution and danger zones, respectively. The Graphic Diver Interface allows you to make quick status checks underwater of your no- decompression status and ascent rate.
  • Page 26 Ascent Rate Indicator currently holds a U.S. Patent. DIVE TIME REMAINING DISPLAY One of the most important pieces of information on the PRODIGY is the no-decompression dive time remaining display (Fig. 19a). The PRODIGY constantly monitors theoretical loading of twelve different tissue compart- ments and calculates no-decompression time based on the amount of nitrogen ®...
  • Page 27 Over 3,000 feet (915 meters) depth calibration automatically changes to read in feet of freshwater rather than feet of seawater. WARNING - Until it has shut itself off, you must not use the PRODIGY at a different altitude than the altitude where it was originally activated. Doing so will result in an error equal to the difference in barometric pressure, and possibly a false dive mode.
  • Page 28 FLYING AFTER DIVING In 1990 the Undersea and Hyperbaric Medical Society (UHMS) published a set of guidelines aimed at minimizing the possibility of decompression sickness due to flying too soon after diving. The UHMS suggests divers using standard air tanks and exhibiting no symptoms of decompression sickness wait 24 hours after their last dive to fly in aircraft with cabin pressures up to 8,000 ft.

  • Page 32: Maximum Depth

    PRODIGY MAXIMUM DEPTH The PRODIGY will display a maximum depth of 250 feet (76 meters). If you exceed that depth, the Depth, Max Depth, and Dive Log readouts will display dashes signifying that you descended out-of-range (Fig. 22). 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.

  • Page 33: Emergency Decompression

    PRODIGY closely because you will enter decompression rapidly. Upon entering decompression the TLBG will enter the red zone and the decompres- sion dive icons will be displayed (Fig. 23). 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.

  • Page 34: Violation Modes

    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.
  • Page 35 The PRODIGY will stay in the Conditional Violation Mode for up to 5 minutes of being shallower than the decompression ceiling. After 5 minutes, it will enter the Delayed Violation Mode (see next section). But, if the Condi- tional Violation is corrected before 5 minutes have elapsed (meaning you ®...

  • Page 36: Permanent Violations

    24 hours after the last dive. DELAYED VIOLATION MODE When the PRODIGY enters Delayed Violation Mode it retains the capac- ity to tell the diver how to get back to the surface. Delayed Violation Mode will be encountered in either of the following decompression situations:...
  • Page 37 PRODIGY. As previously described, you would then need to follow the ceiling toward the surface as the TLBG recedes toward the Caution Zone. Upon...
  • Page 38 After 5 minutes of surface time, the PRODIGY will enter an Immediate Violation and will then revert to the Gauge Mode (see page 35) for 24 hours. IMMEDIATE VIOLATION MODE The PRODIGY enters Immediate Violation Mode when a situation totally exceeds its capacity to predict an ascent procedure.

  • Page 39: Gauge Mode

    “Gauge Mode” up to 24 hours after a dive in which any Immediate or Delayed Dive time avail Violation Mode was entered. Gauge Mode turns the PRODIGY into a digital TLBG instrument without any decompression monitoring functions. Figure 27a All other displays Yes illustrates the changes effected in Gauge Mode.
  • Page 40 WARNING – Never exit the water with the Tissue Loading Bar Graph in the red decompression zone. Doing so greatly increases the risk of decompression sickness, and may result in injury or death. A diver’s metabolism varies from person to person, and even from day to day. If you are feeling slightly less than 100%, or you are in less than perfect physical shape, use the Caution Zone as a visual reference to place a wider margin of protection between you and the no-decompression limit.
  • Page 41 If you ever extend your dive profiles to the maxi- mum limit, Oceanic advises you to bring additional backup instruments with you on your dives, and to log each dive profile during every surface interval.
  • Page 42 (like a car trunk). After the dive, cover the PRODIGY and keep it out of the sun. If inadvertently left in the direct view of the sun, the LCD display may become totally black.
  • Page 43 Oceanic recommends that you carry a backup dive light, in case of primary light failure. SHARING THE PRODIGY The PRODIGY provides information based upon your personal dive profile and therefore must not be “shared” between divers. You should never, under any circumstances, swap your computer with another unit between dives, or share your computer with another diver underwater.

  • Page 46: Before The Dive

    Many dive computers (and dive trips) are ruined by encounters between carelessly tossed computers and weight belts or tanks. If the PRODIGY is attached to a tank in a rack, tuck Fig. 30 – DataLink high the computer into a B.C.
  • Page 47 (if you have a console version). This allows you to keep the PRODIGY nearby when recording dives in your log book or planning the next dive. DURING THE DIVE Keep the PRODIGY protected from abuse underwater by using the console retainers on your B.C.
