The Time To Fly Mode begins displaying four hours after the last dive has ended to assist you with deciding when enough surface time has elapsed to fly. It is part of the Pre Dive Planning Sequence and shows the word “FLY” with a countdown timer below that starts at 20 hours (Fig. 16).

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 on your nodecompression status, ascent rate, and tank pressure.
Variable Ascent Rate Indicator™- VARI The VARI occupies the right middle of the DataMax Pro display (Fig. 19b). The purpose of the VARI is to assist the diver in preventing too rapid an ascent by providing a visual and audible indication of ascent speed. The bar graph is made up of eight triangular segments and is analogous to an ascent rate speedometer. There are various speed “zones” that are color– coded green, yellow, and red. The actual speeds that the VARI segments represent are listed on page 60.

A zero ATR display shows that the diver must now begin their ascent (assuming a 60 ft./ min. ascent rate) to reach the surface with 300 psig of air.
PRIMARY ALARMS POTENTIAL DANGER: P! BEE EP! BE IMMEDIATE DANGER: P... .. E E B P. BEE EP... BE Fig. 22a – Primary audible alarms alert you to impending danger 24 Rogers and Dr. Michael Powell in 1987. Diving Science and Technology® (DSAT), a corporate affiliate of PADI®, commissioned these experiments and now uses the findings in the Recreational Dive Planner™ distributed by PADI. One advantage of using the DataMax Pro is its ability to model many tissue compartments simultaneously.
When the DataMax Pro senses immediate danger to the diver, it emits One Beep per Second until one of the following situations is corrected: • Conditional violation • Ascent rate that exceeds 60 feet per minute (VARI red zone) • Air Time Remaining equals required decompression time • Air Time Remaining equals zero (0:00) SECONDARY DATAMAX PRO ALARMS Permanent Violations – Single Long Beep If you enter a Delayed or Immediate Violation Mode, a Single Long Beep will be emitted.
TURNING OFF THE AUDIBLE ALARM A special Access Mode allows you to turn the Audible Alarm on or off. You can enter this mode by first accessing Dive Log Mode. After Dive Log Mode displays a primary screen for the most recent dive, the secondary screen for that same dive appears. During this secondary screen, press and hold the activation button for at least six seconds to enter the Access Mode. Keep holding the activation button and watch the display.
CO DE NO 30 40 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.
hours, then a 12 hour surface interval before flying is recommended. 2) Following any dive that required a decompression stop, flying should be delayed for at least 24 hours, and if possible, for 48 hours.
HANDLING THE EXTREMES 29
M a. ## DATAMAX PRO MAXIMUM DEPTH The maximum depth the DataMax Pro will display is 249 feet. If you exceed that depth, the Depth, Max Depth, and Dive Log readouts will display “ ” signifying that you descended out-of-range (Fig. 24a). For that dive, you will not see a numeric depth display over 249 feet or a Max Depth indication other than the double dashes. Although the DataMax Pro will withstand the pressures found at 249 feet, the depth that you can still use all its features is much shallower.
C . Z . 1 0 FT S T NO FT 30 40 DEPTH DEPTH EMERGENCY DECOMPRESSION After entering decompression (especially at deeper depths) the Tissue Loading Bar Graph may “fill” the 10, 20, 30 and 40 FT STOP decompression zones rapidly. Once you’ve entered decompression, it is imperative that you ascend toward the required decompression ceiling immediately.
VIOLATION MODES WARNING: If you exceed certain limits, the DataMax Pro will not be able to tell you how to get back to the surface. These situations will make the Pro 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 Pro functions for 24 hours after the last dive of a day in which a violation occurred. There are three different types of Violation Modes that the DataMax Pro can enter depending on the situation.
C . Z . 1 0 FT S T OP # NO FT DE CO M 20 30 40 Conditional Violation – Ascending Shallower than Decompression Ceiling The DataMax Pro will enter a Conditional Violation Mode if you ascend shallower than the decompression ceiling indicated by the Tissue Loading Bar Graph (Fig. 26). A momentary rise above the ceiling, such as with a surge or swell, will cause this to happen. Therefore you should stay slightly deeper than the exact ceiling depth, watching the Pro closely when managing decompression.
M P PERMANENT VIOLATION MODES If you exceed the restrictions of a Conditional Violation Mode, one of two Permanent Violation Modes will be entered; “Delayed Violation Mode” or “Immediate Violation Mode.” Either of these Permanent Violation Modes will result in loss of some computer functions for 24 hours after the last dive.

depths slightly deeper than 40 feet in some situations. If this happens, descend to the shallowest depth below 40 feet where the flashing stops. After waiting until the Tissue Loading Bar Graph recedes into the 30 foot zone, you can then ascend to not less than 30 feet and continue decompressing. After more time, the bar graph will recede into the 20 and then 10 foot zones after which the diver can ascend to less than 20 or 10 feet respectively.
M graph segments are well inside of the green No Decom zone. After five minutes of surface time, the Pro will enter Immediate Violation and operate only in Gauge Mode for twenty-four hours.

Yet, as with all new technology - especially high-tech products used in harsh environments unforeseen things happen. If you do not prepare for the unknown, you might be sorry later.
NIGHT DIVING WITH THE DATAMAX PRO The DataMax Pro uses a high contrast liquid crystal display with large numerals for easy readability in low light conditions. However, the display is not internally illuminated for night diving because of the excessive power consumption that would be required. This means that on night dives, in caves, or any other low light situation you must use your dive light to illuminate the display.
Remaining is displayed at one time, the second diver’s no-decompression information may not even be displayed when needed. A FINAL WORD OF CAUTION Although the DataMax Pro represents the latest in user-friendly dive computer technology, it cannot force you to understand how to use it. Before diving with the Pro, be sure you thoroughly understand its functions and displays. Take the quiz on pages 62 and 63 to test your knowledge.
CARE and MAINTENANCE 43
CARE AND MAINTENANCE The DataMax Pro is a sensitive electronic instrument. Although it has been designed to survive the rigors of diving, it still must be handled carefully to protect from shock, excessive heat, chemical attack, and tampering. The DataMax Pro is protected by an outer rubber boot that, along with the hose, can be cleaned and protected periodically by application of a silicone milk available in dive stores.
DataLink (Fig. 32) high-pressure quick disconnect between your computer and first stage. This allows you to remove the DataMax Pro and keep it nearby when recording dives in your log book or planning the next dive. DURING THE DIVE Keep the DataMax Pro protected from abuse underwater by using the console retainers on your B.C. If you let it hang freely, expect scratches to cover the display face after only a few dives.
