Atmos ai

Compact Air Integrated Computer.

The Atmos ai is a very small, compact console; yet, the information is displayed with large, easy to read digits. It is available with or without a compass; with or without a quick disconnect. 

The Air Time Remaining feature calculates current depth, tank pressure, your breathing rate, ascent time, and decompression status to tell you exactly how much time you can remain underwater. The ATMOS ai continually displays Air Time Remaining via a numerical bar graph in addition to cylinder pressure. You may also display Air Time Remaining in oversized digits at any time with the press of a button. Dive Time Remaining, like Air Time Remaining provides a 'real' number in minutes. This calculation combines Air Time Remaining, Nitrogen and Oxygen absorption, displaying whichever allows less time.

Is it a good idea to check your computer before entering the water? You bet. Could you forget to activate your computer? Sure. The ATMOS ai features push-button or automatic activation, triggered by water contact. A benefit of push-button activation is easily verifying operation and cylinder pressure, but in case you forget, or simply choose not to activate your computer, it can be as simple as jumping in the water. The ATMOS ai 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.

The ATMOS ai 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 ATMOS ai is designed to grow with you, being easily programmed for Nitrox mixtures from 21% to 50%. 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.

AERIS Dive Computers are designed with color-coded bar graphs; green, yellow and red. These graphs monitor three very important diving parameters; nitrogen accumulation, oxygen loading 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.

Customer Reviews

All,

I have over 300+ dives on my old Atmos ai (it has to be 7+ years old) and it continues to perform despite taking a beating nearly every weekend on boat dives that bang equipment around. I have other computers that I use as backups (I have redundancies on all my equipment), but this remains my primary and my favourite.

About two years ago I bought the downloading cable and that has further increased my pleasure and my enjoyment in my Atmos.

Keep it up, Aeris!

Alex Siegel
I am a PADI instructor with approximately 200 dives using this computer. I've had no problems and would highly recommend.
I bought this Computer 3 years ago. It was only used on 3 dive trips, ( 7 dives ) It was last used Sept of 2011. When in the Caymans I went to install a New battery and upon powering up " ALT " came up on the screen and the Computer would not reset. I had to rent gear all week as the computer was useless. I contacted them tonight and will update my findings once someone returns my call or email. As of now I cant recommend something I was only ably to use for 3 trips. $300 a trip?!?!

***** AERIS Response *****
Sorry about the hassle Jason. "ALT" indicates a problem with the depth sensor. The computer's designed to shutdown should this sort of problem be detected. Our customer service team will be happy to help.
I have used several computers throughout my diving, and this is my favorite. The large numbers and intuative layout make it easy to operate and read. I especially like the ability to toggle between screen during a dive. Downloading is easy and the log gives you eveything you need to track and improve your diving.

Air Time Remaining

The Air Time Remaining feature calculates current depth, tank pressure, your breathing rate, ascent time, and decompression status to tell you exactly how much time you can remain underwater. The ATMOS Ai v.2 continually displays Air Time Remaining via a numerical bar graph in addition to cylinder pressure. You may also display Air Time Remaining in oversized digits at any time with the press of a button.

Dive Time Remaining

Dive Time Remaining, like Air Time Remaining provides a 'real' number in minutes. This calculation combines Air Time Remaining, Nitrogen and Oxygen absorption, displaying whichever allows less time.

Oversized Digits

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?

Water or Manual Activation

Is it a good idea to check your computer before entering the water? You bet. Could you forget to activate your computer? Sure. The ATMOS Ai v.2 features push-button or automatic activation, triggered by water contact. A benefit of push-button activation is easily verifying operation and cylinder pressure, but in case you forget, or simply choose not to activate your computer, it can be as simple as jumping in the water.

Audible Alarms with Flashing LED Warning Light

The ATMOS Ai v.2 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.

Air or Nitrox

The ATMOS Ai v.2 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 ATMOS Ai v.2 is designed to grow with you, being easily programmed for Nitrox mixtures from 21% to 50%.

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 brief audible and visual alarm remind 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.

Interactive Menu System

Speed through menu items and set modes easily and quickly with AERIS’s intuitive dual button operation.

Date and Time Stamp

The ATMOS Ai v.2 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.

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.

Graphic User Interface™

Using the recognizable logic of green, yellow and red color-coding in conjunction with bar graphs, the diver has at-a-glance information. As easy to understand as a traffic light, the Graphic Diver Interface helps you to easily monitor No-Decompression status, Oxygen Accumulation, Ascent Rate, and Air Time Remaining.

Automatic Altitude Compensation

All AERIS computers automatically compensate for altitude up to 14,000 feet, giving adjusted no-decompression times and depths. They even automatically recalibrate the depth display for freshwater instead of seawater.

Diver-Replaceable Batteries

All AERIS computers feature diver replaceable batteries. This can be a real trip-saver on board a live-aboard boat!

Battery Hot Swap™

An added benefit to diver replaceable batteries. The “hot-swap” feature allows you to change batteries between dives while maintaining all calculations.

24-Hour Fly Countdown and Calculated Desaturation Time

The ATMOS Ai v.2 features both a dual 12-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 ATMOS Ai v.2’s Variable Ascent Rate Indicator bar graph acts as a speedometer, allowing you to very precisely control your ascent rate via the green, yellow, and red bar graph.

 Depth-Dependent Ascent Rate

The ATMOS Ai v.2 features a depth-dependant ascent rate, allowing increased rates at deeper depths and providing additional safety as you near the surface.

Backlighting

The ATMOS Ai v.2 features an intense bluish green light that illuminates the entire dial of the computer evenly at the push of a button. The backlight may be activated either on the surface, or underwater and remains on for button depression time plus the duration that you choose.

20 Dive On-Unit Log Book

The ATMOS Ai v.2 features on-unit data storage capacity for 20 dives. Date and time stamp makes locating and viewing a specific dive quick and easy.

Optional Computer Interface

The ATMOS Ai v.2 features a watertight, plug-in serial connection for fast and reliable PC download. Feature-rich software provides intuitive post-dive analysis and logging. You have the option to add and/or edit many pieces of information to customize your log book, with data such as depth and decompression status during a dive, maximum depth, bottom time, air consumption, air time remaining, no-decompression status, descent and ascent rate, surface interval, and any violations recorded automatically.

Optional PC Upload

In addition to detailed dive analysis, the optional Computer Interface also allows you to quickly and easily set all of your ATMOS Ai v.2 settings and options directly through your PC.

Advanced Dive Planning Simulator

While AERIS manuals and cue cards are simple to understand, some people learn better through hands-on experience. The on-unit Simulator Mode allows you to run the ATMOS Ai v.2 through actual dive profiles including Air Dive, Nitrox, Gauge Mode, and Decompression. You will see the dive happen on the screen as you would in the water. Air consumption calculations may be activated, using a pre-set rate. As you dive the ATMOS Ai v.2, the simulated consumption rate will be updated to reflect your own average.

While this is not a substitute for reading and understanding your Owners Guide, it provides detailed dive planning, is an excellent auxiliary learning tool, and it is a great way to refresh your memory on the way to the dive site, particularly if you have not been diving for a while. A side benefit is that you can always show your dive buddy what a cool new dive computer you have!

Extended Range Gauge Mode

Divers using advanced breathing gas mixtures or otherwise conducting planned dives beyond the operational limits of the computer may utilize the ATMOS Ai v.2 as an advanced air integrated digital depth gauge and bottom timer with detailed PC Interface.

Split Set Mode Access

With a computer as advanced as the ATMOS Ai v.2, you may have to push a lot of buttons to personalize it just the way you want. We have split the set mode into two separate menus. Set Mode 1 includes Nitrox mix, maximum depth alarm, and other options that may change from dive to dive. Set Mode 2 includes units of measurement, PC sampling rate, and other personal preferences that will most likely be set once and forgotten.

USER SETTINGS AND OPTIONS

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.

Air or Nitrox

The ATMOS Ai v.2 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 ATMOS Ai v.2 is designed to grow with you, being easily programmed for Nitrox mixtures from 21% to 50%.

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 ATMOS Ai v.2 to alert you when your elapsed dive time reaches one hour.

Units of Measurement

Choose between Metric and Imperial settings for depth and pressure.

12/24 Hour Time Format

Choose between 12 or 24 hour time format, independent of Units of Measurement.

Date and Time of Day

The ATMOS Ai v.2 displays time of day on the surface as well as underwater for quick reference. Time and date stamp helps you to easily identify specific dives in On-Unit Log Mode or PC download memory.

Audible Alarm and Flashing LED Warning Light On/Off

You may choose to deactivate all audible and LED alarms.

Nitrogen Tissue Loading Bar Graph Alarm

Many divers have claimed that AERIS’s 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 yellow caution zone, or stay one pixel away, or – you get the point. Now you can program the ATMOS Ai v.2 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

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 ATMOS Ai v.2 feature, you are able to program an audible alarm to alert you upon reaching a pre-set number in minutes.

Maximum PO2 Level (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 ATMOS Ai v.2 lets you set your own limit. Program an audible alarm to sound at the level that you prefer.

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.

Backlight Duration

Would you like the backlight to shut off as soon as you release the button? Would you rather it remain on for 0, 3, or 7 seconds? We don’t need to make these decisions for you; it’s your choice.

PC Interface Sampling Rate

You have the option to choose at which rate (timed or depth transition) the ATMOS Ai v.2 samples and stores data for later download to your PC. More frequent sampling will provide extreme detail of your dive profiles with limited storage capacity. Less frequent sampling, while it provides less detail, can store up to 150 dives!

Extended Range Digital Gauge Mode On/Off

Activate Digital Gauge Mode for freediving or dives conducted beyond the limits of the computer.

Water Activation On/Off

Do you tend to keep your equipment in a wet dive bag longer than you should? Are you an Instructor or Divemaster in an environment where your gear is never dry? Would you like to disable the water activation feature? Now you can.

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.

Diving By The Colors
AERIS Dive Computers are designed with color-coded bar graphs; green, yellow and red. These graphs monitor three very important diving parameters; nitrogen accumulation, oxygen loading and your personal ascent rate. Pixels build up in each of these color-coded areas to give you a quick, easy reference of these perameters. 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.

*Battery Life: Battery life estimates are based on full-capacity batteries, and continuous usage as described.

- 7 days per week

- 2 dives per day

- 1 hour dive time

- 2 hour surface interval

- 18 hour interval from last dive to the first of the next day

**AERIS Dive Computers have user selectable Sampling Rates that determine when data is sampled and stored for subsequent download to associated PC interface programs. More frequent sampling provides more data per dive yet results in storage of fewer dives for download. Use with Air or Nitrox, with or without air integration, dive profiles, and other variables also effect the number of dives that can be stored. Although as many as 150 dives might be stored for consistent 60 foot dives with the Sampling Rate set for a 10 foot rate, as few as 3 may be stored when the profiles fluctuate and the sampling rate is set for a 2 second rate.
