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.
