Immediately after a dive, various information is stored in the DataPlus’ memory and can be viewed by accessing the Dive Log Mode. This gives you a opportu- nity to record data in your log book before it is eventually overwritten by subse- quent data.

  • Page 23: Knowing When To Fly

    DataPlus KNOWING WHEN TO FLY Due to the present lack of a complete data set derived from actual human testing, there are different recommendations cited by various scientific organiza- tions for the amount of time a diver should wait before flying after diving. The DataPlus follows one of the more conservative of these, cited by Divers Alert Network (DAN);...

  • Page 24: Altitude Diving

    The mathematical model within the DataPlus accounts for the reduced No Decompression time available at higher elevations based on NOAA (National Oceanic and Atmospheric Administration) guidelines. When diving in high altitude lakes or rivers from 2,000 to 14,000 feet (610 to 4,268 meters), the DataPlus will adjust automatically, providing corrected depth and reduced No Decompression times.

  • Page 25: Sharing The Dataplus

    DataPlus SHARING THE DATAPLUS WARNING: Never participate in sharing or swapping of a dive computer. Doing so may result in injury or death. The DataPlus provides information based upon a diver’s 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.

    HANDLING EXTREMES...

  • Page 54: Emergency Decompression

    ® EMERGENCY DECOMPRESSION There are few legitimate excuses for making unplanned Decompression dives, and the consequences of this type of diving can be severe. Decompression diving requires special training. The DataPlus is intended for use by recre- ational divers not engaged in intentional decompression diving. De- compression features are provided only for emergency situations.
  • Page 55 It should not be considered, however, that these built-in capabilities provide any im- plied approval or consent from Oceanic for individuals to exceed the defined limits of recreational dive profiles, as agreed on by all interna- tionally recognized training agencies.

  • Page 56: Caution Zone (Tlbg)

    ® WARNING: Existing data for making planned decompression dives is extremely limited, and virtually nonexistent for repeti- tive decompression diving. You must therefore avoid decompres- sion diving and allow a surface interval of at least 24 hours before reentering the water in the event a dive requiring decom- pression is made.

  • Page 57: Decompression Dive Mode

    DataPlus nient way to consistently monitor how close you are coming to the No Decom- pression limit. Oceanic suggests always leaving the water with the TLBG in the green No Decompression (NO DECO) zone. WARNING: Never exit the water with the TLBG in the red Decompression (DECO) zone.
  • Page 58 ® decompression dive time/depth limits are exceeded causing the TLBG to pass the yellow caution (C.Z.) zone and enter the red decompression (DECO) zone. Information provided includes current depth, current required decompression ceiling stop depth and time (and Ceiling Stop icon), and total ascent time that includes stop time at all ceilings and vertical ascent time calculated at 60 feet (18 meters) per minute.
  • Page 59 DataPlus ascending any further, or you will increase your risk of decompression sickness. The amount of decompression credit time you receive is dependent on depth, with slightly less credit given the deeper you are. Still, you must never ascend shallower than your decompression ceiling. Doing so will greatly increase your risk of decompression sickness and place the DataPlus into a Conditional Violation Mode described later.

  • Page 60: Violation Modes

    ® VIOLATION MODES WARNING: If you exceed certain limits, the DataPlus will not be able to tell you how to get safely back to the surface. These situations will make the DataPlus enter 'violation modes' and must be avoided at all costs. They exceed tested limits and can result in loss of some DataPlus functions for 24 hours after the dive in which a violation occurred.

  • Page 61: Delayed Violation Mode

    DataPlus The DataPlus will alert you to the Conditional Violation by flashing the Total Ascent Time display until you descend below the required decompression stop ceiling. If you descend below the required decompression ceiling before 5 minutes have elapsed, the DataPlus will continue to function as if no violation had occurred.
  • Page 62 ® would then need to follow the ceiling stop depths and time toward the surface until the TLBG recedes toward the caution (C.Z.) zone.

Oceanic reminds you that the DataPlus is intended for no decompres- sion diving at depths within 130 feet (39 meters). Expanded capabili- ties of the DataPlus are provided as safety features to assist you with emergency situations.

  • Page 64: Immediate Violation Mode

    These dives represent gross excursions into decom- pression that are beyond the boundaries and spirit of the DataPlus design. If you are following these dive profiles, Oceanic advises you not to use a DataPlus dive computer. Immediate Violation Mode occurs when a Decompression Stop depth much greater than 60 feet (18 meters) is required.

  • Page 65: Gauge Mode

    DataPlus GAUGE MODE Underwater the Gauge Mode is a continuation of the Immediate Violation Mode that turns the DataPlus into a digital instrument without any decompression or oxygen monitoring functions (Fig. 64). After surfacing, Gauge Mode does not provide the Time to Fly, FO2, PO2, and PDPS features.

    130 feet (39 meters). Any deeper dive should be avoided. Special training, equipment and support are necessary for this type of diving. Oceanic does not advocate diving to depths below 130 feet (39 meters), the basis for which is purely theoretical.

  • Page 67: Oxygen Exposure

    DataPlus dives, the DataPlus will allow a maximum of 7 minutes no decompression dive time available at 160 feet (48 meters). Since part of the 7 minutes is used during descent, the actual time available upon reaching 160 feet (48 meters) can be a very short amount of time.
  • Page 68 It should not be considered, however, that these built-in capabilities provide any implied approval or consent from Oceanic for individuals to exceed the defined limits of oxygen exposure, as agreed on by all internationally recognized nitrox training agencies.

  • Page 69: High O2 Accumulation

    DataPlus Oceanic strongly recommends that you avoid exceeding oxygen expo- sure limits, and reminds you that nitrox diving requires special train- ing and understanding of the effects of oxygen toxicity. WARNING: In the event that you exceed the maximum per dive allowable O2 exposure (dose), it is recommended that you allow a surface interval of at least 2 hours before reentering the water.

  • Page 71: Unexpected Loss Of Displayed Information

    This is an important reason to avoid pushing the no decompression and oxygen tolerance limits, and a critical reason to avoid entering decompression. Regardless of your diving habits, Oceanic advises you to dive with additional backup instrumentation that can provide the DATA data necessary to properly surface if and when your primary instruments fail.
