  • Page 6: Introduction

    INTRODUCTION The DataMax Sport was designed to be extremely easy to use and under- stand. This owner’s guide is divided into five sections designed to make it easy to learn how to use the “Sport.” The first two sections will show you how it performs in most diving situations.
  • Page 7 Mode is displayed for three seconds before switching back to the NDC mode. Fig. 2 – Pre Dive Planning Sequence USING THE “GRAPHIC DIVER INTERFACE” To make it easy to check your dive status on the DataMax Sport, a color- coded system of graphic displays is used. This “Graphic Diver Interface” is...
  • Page 8 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.”...
  • Page 9 EMERGENCY DECOMPRESSION If your depth or bottom time is such that the Tissue Loading Bar Graph DataMax enters the red zone, the DataMax Sport will switch to “Decompression Dive ® SPORT ®...
  • Page 10 The longer the surface interval, the more dive time available in the PDPS. IT’S REALLY JUST THAT SIMPLE! The DataMax Sport is designed to help you stay out of trouble with a minimum of effort reading the displays. The Graphic Diver Interface elimi- nates any confusion from looking at too many numbers.
  • Page 11 BOTTOM ing decisions about future dive plans. ALTITUDE DIVING The DataMax Sport automatically compensates for decreased ambient pressure when activated at high altitudes up to 14,000 feet. Its program DataMax contains a high altitude algorithm that reduces no-decompression limits to ®...
  • Page 12 The DataMax Sport follows one of the more conservative of these, cited by Divers Alert Network (DAN); that divers wait at least twelve hours before flying in pressurized commercial aircraft, and at least 24 or more if making repetitive multi-day or decompression dives. The DataMax Sport easily tracks how much surface time has elapsed with the Time to Fly display.

    DETAILED OPERATIONS GUIDE...

  • Page 14: Operational Modes

    During Diagnostic Mode, the DataMax Sport measures its own battery voltage level. If there is not enough battery power to complete a day of diving, the DataMax Sport will either deactivate itself or not activate at all.
  • Page 15 WARNING - If the words “LOW BATT” appear immediately after activation, Oceanic strongly recommends that you DO NOT dive until you have obtained battery replacement - especially if you are starting out on a multi-day dive trip. Although there will usually be...
  • Page 16 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. PDPS no-decompression times are displayed only for depths where there is at least one minute available.
  • Page 17 Temperature. You can easily tell when you are viewing the Alternate Dive Mode because the Graphic Diver Interface bar graphs, and Dive #, disappear. 6. DECOMPRESSION DIVE MODE The DataMax Sport will allow you to avoid, or easily manage, decompres- sion. Before explaining further, read the following warning. °...
  • Page 18 Still, you must never ascend shallower than your decompression ceiling! Doing so will place the DataMax Sport into a Conditional Violation Mode (see page 28) and greatly increase your risk of decompression sickness. Often while coping with surge and swell, it is difficult to stay at a chosen depth. To ensure that you do not enter a violation mode you should stay close to, but no shallower than, the decompression ceiling depth.
  • Page 19 9. DIVE LOG MODE Dive Log Mode can be accessed on the surface by pressing the button on the front of the DataMax Sport (Fig. 13a). Pressing and releasing the button Fig. 13 – Dive Log Mode will start the Automatic Dive Log Sequence. This mode displays information Primary Screen of up to nine dives from your most recent day of diving.
  • Page 20 When accessing Dive Log Mode, you can choose to either press and release, or press and hold, the button on the face of the DataMax Sport. As mentioned, pressing and releasing the button initiates the Automatic Dive Log Sequence, showing previous dives for about four seconds each.
  • Page 21 ® TELLING THE DIFFERENT MODES APART The DataMax Sport’s ten different modes are easy to tell apart. Each is Fig. 15 – Mode Labels clearly marked with Mode Labels (Fig. 15) and occur at different times. Unless you routinely dive to the extremes, you will rarely see Decompression Dive, Violation, or Gauge Modes.

  • Page 22: Informational Displays

    Time to Fly Modes. Become familiar with all ten modes so that you understand exactly what the DataMax Sport is telling you. INFORMATIONAL DISPLAYS Each DataMax Sport numeric or graphic display represents a unique piece of information. The following section describes each display in detail. Depth Display The lowermost portion of the LCD (Fig.
  • Page 23 ™ Two different bar graphs are located around the perimeter of the DataMax Sport LCD (Fig. 17). 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 24 - VARI The Variable Ascent Rate Indicator (VARI) occupies the bottom portion of the DataMax Sport display (Fig. 17b). The purpose of the VARI is to assist the diver in preventing too rapid an ascent by providing a visual indication of ascent speed.
  • Page 25 Recreational Dive Planner distributed by PADI. One advantage of using the DataMax Sport is its ability to model many tissue compartments simultaneously. It constantly updates No decompres- sion Time as the controlling tissue changes with different depths. You always have a current prediction of remaining no-decompression time regardless of which compartment is in control.
  • Page 26 FLYING AFTER DIVING In 1990 the Undersea and Hyperbaric Medical Society 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.

A clean dive is one where there is no residual nitrogen from previous dives. The DataMax Sport will continue to calculate residual nitrogen for up to 24 hours although the dive counter resets to zero after 12 hours.

    practical to stay within the 11 minutes of no-decompression time allowed at 130 feet. If you exceed 160 feet, watch the Sport closely because you will enter decompression rapidly. The Tissue Loading Bar Graph will alert you when entering decompression by entering the red zone (Fig. 22) and chang- ing dive time remaining from NDC to DEC.

  • Page 32: Violation Modes

    VIOLATION MODES If you exceed certain limits, the DataMax Sport will not be able to tell you how to get back to the surface. These situations will make the Sport enter violation mode and must be avoided at all costs. They push decompression theory to the limits and can result in loss of some DataMax Sport functions for 24 hours after the last dive of a day in which a violation occurred.

  • Page 35 After DEC Time reaches zero and the Tissue Loading Bar Graph recedes into the yellow Caution Zone (C.Z.), the diver can surface. However, to add a greater margin of protection, Oceanic strongly recom- mends that you wait until the segments are well within the green No Decom zone, unless a low air condition requires you to surface.
  • Page 36 The DataMax Sport enters Immediate Violation Mode when a situation totally exceeds its capacity to predict an ascent procedure. These dives represent gross excursions into decompression that are beyond the bound- aries and spirit of the DataMax Sport design. If you are following these DataMax ®...

  • Page 37: Gauge Mode

    GAUGE MODE Time to Fly The DataMax Sport will operate with limited functions in what is called “Gauge Mode” up to twenty–four hours after a dive in which any Immediate or Delayed Violation Mode was entered. Gauge Mode turns the DataMax Sport into a digital instrument console without any decompression monitor- ing functions.

  • Page 38: Caution Zone

    Above water, Gauge Mode is indicated by the lack of a Pre Dive Planning Sequence or Time to Fly display. Twelve hours after surfacing, a countdown timer with “triple dash” display will inform you of the number of hours remaining before normal operation can resume (Fig. 27). CAUTION ZONE –...

  • Page 41: Night Diving/Sharing

    SHARING THE DATAMAX SPORT The DataMax Sport 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.

    DataMax Sport. The propellants may chemically attack the plastic. BEFORE THE DIVE If diving with a console version of the DataMax Sport, be careful not to leave it lying on a boat deck where it might be damaged. Many dive comput- ers (and dive trips) are ruined by encounters between carelessly tossed computers and weight belts or tanks.

  • Page 45: During/After The Dive

    AFTER THE DIVE Soak the DataMax Sport in fresh water after each dive. If possible, use lukewarm water to dissolve any salt crystals. Salt deposits can also be dissolved using a slightly acidic vinegar/water bath. After removal from a fresh water bath, place the DataMax Sport under gently running water.
