The Smart is the quintessential dive computer!
Has a perfectly clear display and an exemplary design. Extremely comprehensive and ergonomic, it is also suitable for multimix and free diving.
On the surface, you can adjust the nitrox settings, or view the logbook at a glance.
On the other hand, underwater, the Smart allows you to switch between depth information (shown on the top line), which is completely independent of the complementary information shown on the bottom line. The middle row is dedicated to information on the decompression state.
The buttons have been repositioned to the side, thus favouring a truly compact, ergonomic profile and providing immediate performance. The upper right button manages data regarding the maximum depth, average depth and maximum depth reached by the gas.
The lower right button, on the other hand, adjusts the field next to the dive time, providing temperature, oxygen percentage, CNS, time of day and stopwatch.
The time of day is given a 4-second timeout, after which the dive time will be displayed again for safety.
The battery has a guaranteed burn timeof 2/3 years (depending on the number of dives), and can be easily replaced independently by the user, without any technical support.
Equipped with a two-tone black/white and black/grey strap.
Mares Quad Air Computor
The Quad Air scuba dive computer has a clear display and allows you to view relevant dive data at a glance.
With the Mares Quad Air you can also read the tank pressure directly on the display, via a wireless connection.
The three-sector layout includes all the relevant data, including tank pressure. Extended battery life, user-replaceable.
All the information a diver requires is instant and readable at a glance, thanks to the clear display and giant data viewer.
User interface is divided into three segments:
- one for depth,
- one for time and decompression
- one for cylinder pressure.
For an even more intuitive reading of the data, Mares has increased the communicative effectiveness of the most important parameters by displaying them in bigger numbers, whilst the two secondary parameters are displayed in a way that takes up less space on the monitor.
Among the Quad Air's strengths are its low battery consumption (user-replaceable with standard commercial batteries), which offers up to 150 dives.
During a dive, the four buttons on the dial - those on the left have the same functions as those on the right - are mirrored so that it is always easy to operate the Quad Air regardless of which arm it is worn on.
The 'Runaway Deco Alarm' alerts the user when staying at the current depth will result in a significant increase in mandatory decompression stops; the 'Deco Dive Planner' adapts the surface interval input to your needs.
The multi-blend function, which tunes three different probes and mixtures in a single dive without looking at the gauge, completes Quad Air's customisations.
The main features of the Quad Air dive computer are:
- Extraordinarily clear display with data displayed in giant size
- Integration of tank data without a hose for up to three transmitters
