Introducing the ATMOS ai, Aeris' new air integrated console. 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. Essentially, it is an ATMOS 2 with airtime 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 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 co ntact. 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 assimple 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 potentialdanger, 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).
