Full review: Mares Quad Air

The Mares Quad Air stands out as a premium wrist-mounted dive computer designed for divers who want comprehensive data at a glance without sacrificing readability underwater. Its most defining feature is the large, high-resolution digital display paired with an analog-style depth gauge bezel, giving divers an intuitive dual-reading experience that mimics traditional gauge instruments while delivering the precision of modern digital technology. The screen is generously sized, making it easy to read critical information such as depth, no-decompression limits, and ascent rate even in low visibility or during night dives. Built with rugged construction, the Quad Air is designed to withstand the rigors of frequent diving, whether in tropical reefs or cold, murky waters.

What truly sets the Mares Quad Air apart is its air integration capability, allowing it to wirelessly communicate with a compatible transmitter attached to the diver's tank valve. This means real-time monitoring of tank pressure and remaining air time directly on the wrist display, eliminating the need to constantly check a separate gauge console. The computer supports multiple diving modes, including air, nitrox, and gauge modes, making it versatile for recreational divers who may explore different diving disciplines over time. Its algorithm, the RGBM (Reduced Gradient Bubble Model), calculates decompression information with a focus on diver safety, factoring in variables like altitude and repetitive dive profiles to give accurate, conservative guidance throughout a dive session.

Beyond its core diving functions, the Mares Quad Air offers user-friendly navigation through a simple button interface, allowing divers to switch between screens and access logbook data, dive history, and settings without complicated menus. The rechargeable battery and USB connectivity add a layer of modern convenience, letting divers download dive logs to their computer or mobile device for detailed post-dive analysis. Its comfortable wrist strap and moderate size make it suitable for extended wear, whether during a single dive or a multi-day liveaboard trip. Overall, the Quad Air caters to divers who value a blend of traditional analog aesthetics with the functional benefits of digital air integration, making it a reliable companion for both recreational adventurers and more serious sport divers looking to track their performance and safety metrics dive after dive.
