It seems ridiculous to explain to someone that looking at their watch or console takes so much effort that this mask is a great benefit - but after diving it, you quickly begin to realize just how much of a distraction monitoring your instruments actually is – and how liberating diving “hands-free” can be. Imagine driving down the freeway and having to reach down to locate a gauge to check your speed. Diving with the DataMask makes monitoring your dive data just as easy. Before you complete the thought “I wonder how much air I have?” or “How deep am I?” or “Am I ascending too fast?” – You have the answer – instantly. Imagine how enjoyable it is to complete an entire dive without taking your eyes off the reef, ever. Ascents are completely changed – you’ll see people ascend trying to manage their buoyancy and check their gauges with their left hand while their right is holding a line, assisting a buddy, shining a light on their gauge, or a combination of them all and appreciate your DataMask more than ever. Safety stops are a completely different experience - with the DataMask you’re perfectly able to observe your surroundings while seeing current depth and countdown time. For anyone that has downloaded their dives, you’ll find that regardless of buoyancy skills, most divers experience fairly significant depth and ascent rate fluctuations without ever knowing it. With the DataMask, these variations are instantly recognized, giving you an opportunity to correct them – ultimately providing much greater control and safety during the dive. And finally, you’ll enjoy the ability to easily monitor your air time remaining – and will see immediate benefits of reduced air consumption.
In-Mask Digital Optic System
The DATAMASK contains a miniature liquid crystal display (LCD) panel, proprietary Digital Optic System, microprocessor, depth transducer, wireless cylinder pressure receiver, diver replaceable battery, and controlling software. The miniature LCD allows you to keep your eyes focused on the dive while presenting critical dive data including: current depth, elapsed dive time, cylinder pressure, and dive time remaining. The Digital Optic System provides a clear, highly magnified image of the LCD, which is viewable regardless of environmental conditions and may be seen clearly by the vast majority of people, regardless of vision.
Wireless Air Integration
The DataMask HUD is a sophisticated Personal Dive Computer featuring Oceanic's wireless air integration technology. A transmitter threaded into the first stage high-pressure port continuously sends cylinder pressure data to the mask. Frequencies are individually coded to allow multiple divers to swim side by side without interference with other units. Because the transmitter and display module are independent and separately powered units, the mask may also be easily used as a stand alone, non-air integrated dive computer.
Advanced Free Dive Mode
The DataMask HUD provides accurate depth and time with an amazing 1-second sampling rate for subsequent PC download and analysis. Dive Time is displayed in seconds and minutes. Custom audible alarms include Elapsed Dive Time, Countdown Timer and (3) Independent Max Depth Alarms. The DataMask HUD is the first Free Diving Computer to calculate and track Nitrogen Tissue Loading, allowing you to switch between SCUBA dives and Free Dives on the same dive day.
Patented Air Time Remaining Algorithm
You're at 80 feet with 1300 psi remaining in your cylinder - how long before you need to begin an ascent to a shallower depth? Our patented Air Time Remaining feature calculates your current depth, breathing rate, cylinder pressure, ascent time, and decompression status to tell you exactly how much time you can remain underwater.
Full-Time Air Time Remaining Display
The DataMask HUD’s primary dive mode always displays approximate Air Time Remaining in 10 minute increments.
Dive Time Remaining
Dive Time Remaining, like Air Time Remaining provides a 'real' number in minutes, considering Air Time Remaining, Nitrogen and Oxygen absorption, and automatically displays whichever allows less time.
Turn-Around Pressure Alarm
The 'Turn-Around' Pressure Alarm is a unique patent-pending feature that allows you to pre-program an audible reminder when you reach 1000 to 3000 psi in 250 psi increments. This helps ensure that you return to your exit point with plenty of air.
Take the Oceanic challenge: When shopping for a new dive computer, compare the displays. When it comes to viewing critical information, which would you rather see at 100 feet?
The DataMask HUD features a variety of system and user-customized audible alarms, alerting you to situations that pose a potential danger, or simply serve as a convenient reminder.
Audible Alarm Acknowledgement™
Have you ever had difficulty hearing your computer's audible alarm? Perhaps that little beep signifying a potentially dangerous situation was timed perfectly with your exhaust bubbles rushing past your ears. Or maybe it seemed insignificant as that huge manta ray soared overhead. You won't miss the DataMask HUD's audible alarm. Once triggered, the alarm will sound continuously for 10 seconds. We know what you're thinking. "That's nice, I'll definitely hear the alarm, but isn't that going to annoy me and everyone else in the water?" We thought of that too. The alarm's job is to get your attention so that you look at the computer. Once it does that, simply press the button and it will stop. You're a responsible diver and the DataMask HUD treats you that way.
Air or Nitrox
The DataMask HUD acts simply as an 'Air' computer until you tell it otherwise, whether that is this weekend or 2 years down the road.
Oceanic Personal Dive Computer Algorithm
Decompression theory can be trusted only as far as it has been demonstrated by actual test dive data. In 1987 a unique series of experiments were conducted by Diving Science and Technology (DSAT). Commissioned by the Professional Association of Diving Instructors (PADI), these Doppler ultrasound monitored human experiments conducted by Dr. Michael Powell produced the most comprehensive data set that exists for recreational divers to this day. These data were used to validate the PADI Recreational Dive Planner and are the basis of the algorithm used in all Oceanic Personal Dive Computers (PDCs).
Personal Conservative Factor Adjustment
When the Conservative Factor is set On, the no-decompression limit times are reduced to values equivalent to those that would be available at the next higher 3000 foot (915 meter) altitude.
"The Ultimate Adjustable Algorithm"
That's the way divers, instructors and Authorized Dealers refer to Oceanic PDCs. Our tissue loading bar graphs provide complete control of your margin of safety for each dive. Want to be a bit more cautious? Make it a personal rule to never enter into the caution zone; or stay one or more pixel away. Now you can even program several of our PDCs to do it for you with our patent pending Nitrogen Bar Graph Alarm; set it once and let the DataMask HUD alert you when your bar graph reaches that level.
No Deco Safety Stop Prompt with Adjustable Depth and Time
An audible and visual alarm remind you as you approach your programmed no decompression safety stop depth and an automatic timer counts down to zero. As in any other dive mode, you still have access to other pieces of information, and there is no penalty should you choose to disregard the safety stop.
FastSet User Interface
Speed through menu items and set modes easily and quickly with Oceanic's FastSet Menu and intuitive button operation.
Date and Time Stamp
The DataMask HUD features time of day on the surface as well as underwater for quick reference. Time and date stamp also helps you to easily identify specific dives in Log Mode or PC download memory.
An alphanumeric "Message Box" is incorporated in the upper portion of the DataMask HUD display to provide text and numeric readouts in simple, unambiguous terms. Imagine beginning an ascent and as the ascent speed increases hearing a warning beep from the DataMask HUD as the message box alerts with the words "TOO FAST".
Automatic Altitude Compensation
The DataMask HUD automatically compensates for altitude dives up to 14,000 feet, giving adjusted no-decompression times and depths. The DataMask HUD even automatically recalibrates the depth displays for freshwater instead of seawater above 2,000 feet.
The DataMask HUD and wireless transmitter feature diver replaceable batteries. This can be a real trip-saver on board a live-aboard boat!
Battery Hot Swap
Should you be in a tight spot between dives, the "hot-swap" feature allows you to change batteries between dives while maintaining all calculations.
24-Hour Fly Countdown and Calculated Desaturation Time
The DataMask HUD features both a 24-hour countdown timer and calculated Desaturation Time, the theoretical time required to off-gas all residual nitrogen at sea level.
Depth-Dependent Ascent Rate
The DataMask HUD features a depth-dependant ascent rate, allowing increased rates at deeper depths and providing additional safety as you near the surface.
Adjustable OceanGlo® Backlighting
Backlighting may be adjusted before the dive or "on-the-fly" underwater for brightness as well as full-time or on demand use.
24 Dive On-Unit Log Book
The DataMask HUD features on-unit data storage capacity for 24 dives. Date and time stamp makes locating and viewing a specific dive quick and easy .
History Mode displays accumulative information for up to 9999 dives, 9999 dive hours and the maximum depth achieved. History information is maintained indefinitely, even if the battery is replaced .
OceanLog® PC Download and Settings Upload Interface
Oceanic's DataMask HUD OceanLog PC Interface is an exquisitely detailed digital dive log. OceanLog allows you to easily transfer dive data from your DataMask HUD to your PC via a plug-in USB cable. Following download, your dive data is automatically formatted for easy viewing, sorting, analysis, and printing.
