Mares Quad Air LED Computer Written by: Debra Davis Created: 01/15/2018 Updated: 09/25/2026

Jumbo Size and Air Integrated!

Like the Mares Quad, the Quad Air is a dive computer capable of both air and nitrox plus multi-gas switching. It still has four intuitive buttons that make this large, jumbo character, magnificently clear display’s set-up and operation simple enough to learn in just a few minutes. However, unlike the Quad, the Quad Air is air integrated and can receive data for up to three transmitters at once. Not only can you monitor your own tank’s pressure, you can also monitor the tanks of two of your dive buddies at the same time! Mares transmitters even have different color LEDs that alert your dive buddy of a low air situation during your dive. The Mares Quad Air is highly functional, looks great, and fits perfectly on your wrist.

Technologies

Mineral Glasst Display

The Mares Quad Air has a mineral glass display that combines tempered glass with superior scratch resistance. The jumbo character display provides improved readability in all diving conditions and from all viewing angles.

Segment Display

The segmented three-row layout comprises all relevant data including tank pressure and even has two customizable fields for ancillary information. The needle-sharp display combined with intelligent placement of information provides the Mares Quad Air with the easiest readability.

Gas Switching

You can set your Quad Air computer to include one or more oxygen enriched gases (up to 99%) in addition to your main gas. This will allow you to benefit from shorter decompression times by switching gases during the dive.

Keep your Quad Air dive computer up-to-date with the latest Mares software developments. Programs available for download are compatible with both MAC and PC computers.
