The Quad Air scuba diving computer is a reliable, intuitive, and customizable choice for divers who value ease of use and reliability. It features a three-segment display layout, low battery consumption, and hoseless tank data integration for up to three transmitters. With such great qualities, the Quad Air is sure to enhance any diving experience. The Quad Air scuba dive computer is reliable, intuitive and easy to use. With its clear display and large data viewer, the Quad Air allows divers to instantly and easily read their depth, time, decompression, and cylinder pressure at a glance. The user interface is divided into three segments, with the most important parameters displayed in bigger numbers for increased communicative effectiveness. One of the Quad Air's key strengths is its low battery consumption, which allows for up to 150 dives on a single user-replaceable commercial battery (for battery replacement, please contact your local Mares dealer. Refer to the Mares Locator). Additionally, the Quad Air can integrate tank data for up to three transmitters (sold separately), providing quick and intuitive communication to the diver and their companions. The transmitters use radiofrequency and feature a color-coded LED that changes from green (above 180 bar) to yellow (100 bar) to red (50 bar) to indicate the tank pressure level. The Quad Air features mirrored buttons on the dial, which makes it easy to operate regardless of which arm it is worn on. It also includes a 'Runaway Deco Alarm' that alerts the diver when staying at the current depth will result in a significant increase in mandatory decompression stops, and a 'Deco Dive Planner' that adapts the surface interval input to the diver's needs.
