FEATURES
In-Mask Digital Optic System
The CompuMask 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 CompuMask HUD Wristwatch PDC is a sophisticated Personal Dive Computer featuring AERIS' wireless air integration technology. A transmitter threaded into the first stage high-pressure port continuously sends cylinder pressure data to the wristwatch. 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 CompuMask 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 CompuMask 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 CompuMask 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.
Oversized Digits
Take the AERIS 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?
Audible Alarms
The CompuMask 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 CompuMask 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 CompuMask HUD treats you that way.
Air or Nitrox
The CompuMask HUD acts simply as an 'Air' computer until you tell it otherwise, whether that is this weekend or 2 years down the road.
AERIS 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 AERIS 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 AERIS 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 CompuMask 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 AERIS' FastSet Menu and intuitive button operation.
Date and Time Stamp
The CompuMask 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.
Alphanumeric Display
An alphanumeric "Message Box" is incorporated in the upper portion of the CompuMask 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 CompuMask HUD as the message box alerts with the words "TOO FAST".
Automatic Altitude Compensation
The CompuMask HUD automatically compensates for altitude dives up to 14,000 feet, giving adjusted no-decompression times and depths. The CompuMask HUD even automatically recalibrates the depth displays for freshwater instead of seawater above 2,000 feet.
Diver-Replaceable Batteries
The CompuMask 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 CompuMask 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 CompuMask 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 CompuMask 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
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 .
ACI PC Download and Settings Upload Interface
AERIS' ACI PC Interface is an exquisitely detailed digital dive log. OceanLog allows you to easily transfer dive data from your CompuMask 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. Enter location, dive buddy and your notes and you've instantly created your own digital logbook.
In addition to detailed dive analysis, the ACI PC Interface also allows you to quickly and easily set most of your user settings and options through your PC.
Gauge Mode
Divers using advanced breathing gas may utilize the CompuMask HUD as an advanced air integrated digital depth gauge and bottom timer with detailed PC Interface.
Split Set Mode Access
To make easy work of customizing your CompuMask HUD, our user settings and options are organized in one of four set modes. Set F (FO2) includes all Nitrox settings. Set A (Alarms) allows you to activate and customize all audible alarms. Set U (Utilities) includes units of measurement, PC sampling rate, transmitter link codes, and conservative factor settings, and Set T (Time) includes date and time.
USER SETTINGS AND OPTIONS
Air or Nitrox
The CompuMask HUD acts simply as an 'Air' computer until you tell it otherwise, whether that is this weekend or 2 years down the road. As your training and experience grow, the CompuMask HUD is designed to grow with you, being easily programmed for Nitrox mixtures from 21% to 50%.
FO2 50% Default On/Off
Following a Nitrox dive, many dive computers calculate your next dive based on a "worse-case scenario", mix of 50% Oxygen and 79% Nitrogen should you forget to reset your actual mix. With FO2 50% Default OFF, your mix remains at the original set point until you change it again.
Receiver ON/OFF
Since the only information sent by the wireless transmitter is cylinder pressure and transmitter battery status, the CompuMask HUD is actually a fully functional Personal Dive Computer without air integration features when the Receiver is set Off.
Dive Mode Selection
Activate Digital Gauge Mode for dives conducted beyond the limits of the Air/Nitrox computer, Free Dive Mode or NORM Mode for Air and Nitrox dives.
Audible Alarm On/Off
You may choose to deactivate all audible alarms.
Maximum Depth Alarm
The Maximum Depth Alarm provides an audible warning upon reaching your planned maximum depth. This is an important safety feature for deeper dives or less experienced divers, and it comes in handy for rebreather diving where you can pre-set another level of safety.
Elapsed Dive Time Alarm
You're on a boat trip and the captain says, "Dive your own profiles, but be back in an hour - we're having lunch!" Just set your CompuMask HUD to alert you when your elapsed dive time reaches one hour.
Nitrogen Tissue Loading Bar Graph Alarm
AERIS' trademark nitrogen bar graph design provides the ultimate user-adjustable computer. Want to be a bit more cautious? Make it a personal rule to never enter into the caution zone, or stay one pixel away, or - you get the point. Now you can program the CompuMask HUD to do it for you. Set it once and let your computer alert you when your bar graph reaches a pre-determined level.
Dive Time Remaining Alarm
Dive Time Remaining provides a 'real' number in minutes. This calculation considers both Nitrogen and Oxygen absorption, displaying whichever allows less time. With this unique CompuMask HUD feature, you are able to program an audible alarm to alert you upon reaching a pre-set number in minutes.
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.
Ending Pressure Alarm
Air Time Remaining calculations are based on the 'Ending' Pressure Alarm. You define how much air you want in reserve upon reaching the surface.
Maximum PO2 Level Alarm (Nitrox)
When diving Nitrox, do you prefer your maximum PO2 exposure to be 1.2 ATA? 1.6 ATA? Depending on where you learned and your own personal comfort zone, the answer may be very different from diver to diver. The CompuMask HUD lets you set your own limit. Program an audible alarm to sound at the level that you prefer.
Water Activation On/Off
The CompuMask HUD automatically enters Dive Mode when the water contacts are wet, and the unit is submerged past 4 feet. To avoid this when swimming or enjoying other water sports, simply set Water Activation Off.
Units of Measurement
Choose between Metric and Imperial settings for date, temperature, depth and pressure.
Automatic Safety Stop Prompt with Adjustable Depth and Time
Set the Automatic Safety Stop Prompt On or Off. Set the Stop Depth to 10, 15 or 20 feet and the Stop Time to 3 or 5 minutes.
Personal Conservative Factor
Set the Conservative Factor On to further reduce your exposure to decompression sickness.
User-Defined Backlight Duration and Intensity
Would you like the backlight to shut off as soon as you release the button? Would you rather it remain on for 0, 5, or 10 seconds? Would you rather it remain on continously during the dive? We don't need to make these decisions for you; it's your choice. The CompuMask HUD even allows you to make modifications to these settings "on-the-fly" during the dive.
PC Interface Sampling Rate
You have the option to choose at which rate the CompuMask HUD samples and stores data for later download to your PC.
Transmitter Link Code
The CompuMask HUD wireless transmitter sends an encoded serial number, so that multiple units may be used side-by-side without interference.
