CHOOSE YOUR DIVE MODE DISPLAY - ON THE FLY
The XR-1 Nx is as versatile underwater as it is topside. Upon starting your dive, the XR-1 NX will simply display your current depth and how long you can stay there (Dive Time Remaining). While many divers have asked for such simplicity and ease of use, you know that with all the XR-1 Nx's features, there must be more - and there is. Simply press the button to see more information. Is this information important to you on a full time basis? Leave it there. Just want to check it and then move on to another display? You can do that too. It's up to you and your new XR-1 Nx.
DIVE TIME REMAINING
Dive Time Remaining provides a 'real' number in minutes, considering Nitrogen and Oxygen absorption, and automatically displays whichever allows less time.
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?
"HOCKEY PUCK" MODULAR DESIGN
Allows easy upgrade from most analog gauge or computer consoles. This innovative modular design allows versatile configurations from our 2 and 3-Gauge consoles, wrist mount, hose-mount boot, or a retractor attached to your BC.
AIR OR NITROX
The XR-1 Nx acts simply as an 'Air' computer until you tell it otherwise, whether that is this weekend or 2 years down the road.
AERIS 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 Dive Computers.
"THE ULTIMATE ADJUSTABLE ALGORITHM"
That's the way divers, instructors and Authorized Dealers refer to AERIS Dive Computers. 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.
DIVING BY THE COLORS
AERIS Dive Computers are designed with color-coded bar graphs; gray, yellow and red. These graphs monitor nitrogen accumulation and your personal ascent rate. Pixels build up in each of these color-coded areas to give you a quick, easy reference of these parameters. Proper monitoring of these graphs allows you to select the personal degree of conservatism you wish to build into each dive, putting you in control of your margin of safety.
AUTOMATIC SAFETY STOP PROMPT
A visual alarm reminds you as you approach 15 feet. An automatic 3-minute 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.
USER FRIENDLY MODE ICONS
All AERIS computers feature bar graphs and universal icons that help you to quickly understand the information displayed on the screen at a glance.
TIME STAMP
The XR-1 Nx features time of day on the surface as well as underwater for quick reference.
AUTOMATIC ALTITUDE COMPENSATION
The XR-1 Nx automatically compensates for altitude dives up to 14,000 feet, giving adjusted no-decompression times and depths. The XR-1 Nx even automatically recalibrates the depth displays for freshwater instead of seawater above 2,000 feet.
DIVER-REPLACEABLE BATTERY
The XR-1 Nx features a diver replaceable battery. 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 XR-1 Nx features both a 24-hour countdown timer and calculated Desaturation Time, the theoretical time required to off-gas all residual nitrogen at sea level.
VARIABLE ASCENT RATE INDICATOR™
Some computers simply flash an icon, telling you that you’re ascending too quickly. The XR-1 Nx’s Variable Ascent Rate Indicator bar graph acts as a speedometer, allowing you to very precisely control your ascent rate via the gray, yellow, and red bar graph.
DEPTH-DEPENDENT ASCENT RATE
The XR-1 Nx features a depth-dependant ascent rate, allowing increased rates at deeper depths and providing additional safety as you near the surface.
12 DIVE ON-UNIT LOG BOOK
The XR-1 Nx features on-unit data storage capacity for 12 dives. Dive numbering and time stamp makes locating and viewing a specific dive quick and easy.
USER SETTINGS AND OPTIONS
FO2
The XR-1 Nx 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 XR-1 Nx 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.
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 XR-1 Nx lets you set your own limit.
WATER ACTIVATION ON/OFF
The XR-1 Nx 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.
