To learn how to get the most out of your gear underwater, discover the [AquaExposure Training](/lms). ## 1. Introduction
Learning scuba diving often exposes students to a significant cognitive overload.
Ask any instructor what causes the most problems during initial dives.
The answer invariably revolves around the difficulty of reading and understanding information displayed on a console that is being tossed about by the current.
A dive computer is more than just a mathematical calculation tool.
It is the vital interface that must translate your security level into a fraction of a second.
Clarity, reliability, and ease of use should be immediately apparent without requiring any interpretation or effort.
With the Mares Quad Air, the Italian manufacturer has taken its largest screen model and integrated wireless air management.
The goal is to provide such absolute clarity that even water with a high concentration of particles no longer detracts from the diving experience.
This test aims to determine whether this giant of segmented display technology remains relevant today.
We will analyze its capabilities in relation to the arrival of its colored counterparts and evaluate its RGBM algorithm.
Overall score: 3.4/5
| Criterion | Score | What it means |
|---|---|---|
| Algorithm & levels | 3.4/5 | Proprietary Mares-Wienke RGBM algorithm, solid but closed to fine adjustments. |
| Air & multi-gas | 2.5/5 | Three Nitrox gases ideal for recreational diving, but no Tek or Trimix functions. |
| Screen & ergonomics | 3.5/5 | Giant segmented LCD screen, unbeatable contrast, operable with four large buttons. |
| Battery life | 3.7/5 | Excellent battery life thanks to a low-power display and an easy-to-replace CR2450 battery. |
| Connectivity & app | 3.0/5 | Reliable, but requires the purchase of an external interface to export the logbook. |
| Compass & instruments | 2.5/5 | No electronic compass, compensated by a good depth gauge mode. |
| Resistance & depth | 4.1/5 | Hardened plastics and scratch-resistant mineral glass, certified for depths up to 150 meters. |
| Price & customer service | 4.1/5 | The comfort of a giant screen with integrated air at a reasonable price, supported by Mares' customer service. |
The decompression management relies on a proven mechanism that will not let you down.
The Quad Air is based on the proprietary Mares-Wienke RGBM algorithm, which uses ten tissue compartments.
This mathematical model is very safe for recreational diving.
However, it does not offer adjustment of the Gradient Factors, nor does it support the use of the Bühlmann ZH-L16C model.
The display of the levels is very, very, very clear on the main screen.
The total ascent time and the depth of the platform are immediately identifiable.
The device triggers audible and visual alarms in case of a rapid increase or breach of setpoint.
This computer will seamlessly support your learning progress without any issues.
It will faithfully guide you up to the threshold of light technical diving.
The device can manage up to three different gases, whether it be air or Nitrox with oxygen concentrations ranging from 21% to 99%.
This feature allows you to easily schedule accelerated decompression processes.
However, it does not include any Trimix functions or a mode for closed-circuit rebreathers.
It is the true powerhouse of the Quad range.
The screen is large and intelligently divides the space into three main sections.
This open design prevents the diver's eye from becoming overwhelmed.
The segmented LCD screen measures over 2.2 inches diagonally.
Key information such as the depth and pressure of the block are displayed in very large font sizes.
The four buttons located in the corners allow for very intuitive navigation.
You won't need to search through lengthy menus, even when wearing thick waterproof gloves.
The main advantage of a monochrome LCD screen is its very low power consumption.
This technology eliminates the hassle of daily recharging between dives.
The computer is powered by a CR2450 button battery that you can replace yourself.
The Quad Air offers approximately 150 dives of battery life with a single charge.
The use of the wireless sensor for air management will consume the battery a bit faster.
The data transfer system is fully functional in daily use.
However, it exhibits a slight technological lag compared to recent models.
The dive log stores approximately 100 hours of dive profiles, with data sampled every five seconds.
The device does not have Bluetooth built into its casing as a standard feature.
To transfer your dive data to the smartphone app, you will need to purchase a separate interface.
You will have the option of choosing between the USB Dive Link 2 cable or the Bluetooth Bluelink Pro connector.
The device focuses exclusively on its primary function.
It manages air and decompression with remarkable efficiency.
Therefore, underwater navigation will be done in the traditional way using a separate instrument.
The Quad Air does not have an integrated electronic compass.
However, it includes a depth sounder mode that is very useful for specific applications.
This mode displays the resettable average depth and includes a precise timer.
The rectangular casing is designed to withstand the inevitable impacts.
It will perfectly withstand impacts from boats or against blocks.
The computer features a tempered mineral glass that offers excellent resistance to abrasion.
The superficial scratches are very well contained by this hardened material.
The maximum depth of use certified by the manufacturer is 150 meters.
By offering air management on a screen of this size, Mares is making a significant impact.
The brand positions this model in a very competitive price range.
The price-to-performance ratio is excellent for an all-in-one computer of this size.
The density of the distribution network ensures rapid support in case of hardware issues.
The Mares Quad Air is primarily designed for recreational divers or those who dive with a club.
It will be the ideal companion for levels 1 through 3.
It's the perfect device for those who want all their data displayed on a single giant screen.
You will never have to squint again to read your pressure levels or air reserve.
This computer, however, is not ideal for advanced technical divers.
Those who want to modify their Bühlmann gradient factors will have to look elsewhere.
It will also not be suitable for those looking for a modern color matrix display.
The after-sales service of Mares elicits polarized opinions within the community.
Some divers report that material exchanges occurred in just eight days.
Other users report occasional delays or some inflexibility regarding shipping costs.
The local reseller acts as a crucial intermediary between the manufacturer and the end customer.
The quality of your service will largely depend on the professionalism of the store where you purchased it.
The ability to replace the battery by the user is a major advantage for travelers.
You can place two spare CR2450 batteries in your first aid kit.
This approach ensures that you will never miss a dive because you forgot your charger.
It's a very practical solution for long cruises where access to electricity is sometimes limited.
The generous battery life of the LCD screen largely compensates for the absence of a rechargeable battery.

If you're looking for a more compact watch format for everyday use, the Mares Sirius is worth considering.
You can find our detailed analysis on the page Mares Sirius dive computer review: A device for both technical and recreational diving..
For those who prefer a high-definition color screen with a Bühlmann algorithm, the new model in this range is very interesting.
