The functions of the Quad Air computer can be grouped into three categories, each corresponding to a specific mode of operation. Surface mode: Quad Air is dry on the surface.
You can change settings, review your logbook, use the dive planner, see remaining desaturation after a dive, download to PC and much more. Dive mode: Quad Air monitors depth, time, tank pressure (optional), temperature and performs all decompression calculations; dive mode itself can be broken down into 4 sub categories: - pre-dive (Quad Air is on the surface but actively monitoring ambient pressure, so that it can begin to calculate a dive the instant it is submerged below 4'/2 meters); - dive - surfacing (Quad Air is on the surface at the end of a dive; dive time calculation is halted but if the diver submerges within three minutes the dive is resumed including the time spent on the surface); - post-dive (after the three minutes of surfacing mode, Quad Air closes the logbook and reverts to a display showing desaturation time, no-fly time and surface interval; this lasts until the desaturation and the no-fly time both have been reduced to zero).Sleep mode: the computer is on the surface after 1 minute without operation (3 minutes from pre-dive mode). Though the computer appears to be turned off completely, it is still active.
Quad Air computes tissue desaturation and checks the ambient pressure once every 20 seconds for uninterrupted monitoring of the environment. Magnificently clear display with jumbo size information. Hoseless tank data integration for up to three transmitters. Three-row layout comprises all relevant data including tank pressure. Two customizable fields for ancillary information.
Four buttons for intuitive user interface. Mirrored button function during dive. Option to view dive time including seconds.
Decompression dive planner with user adjustable surface interval. Long battery life, user replaceable.
