Mares Quad Air

Maximum operating depth (MOD)

Water resistance

The level to which the device can withstand water pressure without leaking or getting damaged.

Gases

The number of gases the dive computer support

Nitrox support

Trimix support

Gas mixture containing oxygen, nitrogen, and helium, aimed at reducing risks in deep technical dives.

Fresh and sea water support

Gauge mode

Residual nitrox reset

Allows divers to clear memory of past nitrogen and oxygen levels to safely switch between different nitrox mixes for new dives

Deco dive planner

A "Deco" (Decompression) Dive Planner is a tool for scuba divers to plan dives exceeding the no-decompression limit (NDL), necessitating calculated stops during ascent for safe nitrogen release from the body.

No fly time indicator

The necessary surface interval a diver must wait before flying after a dive, calculated to prevent decompression sickness by allowing excess nitrogen to safely dissipate from the body.

Deep stop

Dive time maximum

Surface time maximum

Ascent rate indicator

Planner mode

Allows users to simulate the decompression of multiple dives and set surface intervals between them

Altitude selection

The altitude selection in a dive computer adjusts the decompression model to account for reduced atmospheric pressure at higher elevations, ensuring safer dive planning and decompression calculations.
