You have an Oceanic Air Integrated Hose-Less Dive Computer and want to get rid of your submersible pressure gauge and hose to take advantage of the air integrated feature. This Oceanic Transmitter will work with many of Oceanic's computers that are air integrated. If you have an OC1, Atom 1.0, 2.0 & 3.0, VT, VT3, V, VT, VT3 and VT4 and want to upgrade or need to replace your transmitter this item is what you want. Each compatible Oceanic Hose-Less Air Integrated Computer may be programmed to link with up to 3 independent transmitters. The transmitter has a user replaceable 3.6v CR2 battery and when installed to your regulators 7/6" threaded high pressure (HP) port with provide the computer with the following unique features.

Air Time Remaining:
The Air Time Remaining (ATR) 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 dive computer 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. When using, the transmitter option the computer with display gas pressure from 0 to 5000 psi (0 to 350 bars).

Dive Time Remaining:
Dive Time Remaining (DTR), like Air Time Remaining provides a 'real" number in minutes. This calculation combines nitrogen and oxygen absorption, displaying whichever allows less time. Displayed as DTR on the No Deco Main Screen, the graphic NDC, or OTR will identify which time is being displayed. NDC is the maximum amount of time that you can stay at your present depth before entering decompression. During nitrox operations oxygen accumulation during a dive or a 24-hour period, is displayed as a percent of oxygen saturation allowed per dive or per day.
