The innovative Mares Quad Air Wrist Dive Computer is a step-up from the Quad. Able to read tank pressure, the Quad Air receives data directly from the dive tank via an optional wireless transmitter Optional. The computer also includes a magnificently clear display, with jumbo size information, three-row layout with two customizable fields for ancillary information and four buttons for intuitive use. Additionally, the device has a multi-gas capability, decompression dive planner with user adjustable surface interval and comes with a user replaceable battery.

Let's look at the functions of Quad Air in some more detail. They all 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. The dive mode on Quad Air can be broken down into 4 subcategories:

• 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 (Quad Air monitors depth, time, tank pressure (optional), temperature and performs all decompression calculations)
• 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.
