Choosing your first dive computer is often a pivotal moment in a diver's life. You look for simplicity, hope for reliability, and inevitably consider the price. The Mares Puck Lite enters the market with a clear promise: to offer essential safety features, along with modern connectivity, without breaking the bank. I have seen countless entry-level models come and go over the years, some too complex, others too limited. This model positions itself in a very specific niche: immediate accessibility. It doesn't aim to impress the technical diver, but rather appeals directly to those who want to get in the water with peace of mind. Let's analyze together what this small device truly offers, beyond its specifications.
Overall Score: 3.3/5
Decompression is handled by a modern engine, although it has been intentionally simplified to avoid overwhelming beginners with complex settings.
To learn more:The Puck Lite uses the Bühlmann ZH-L16C algorithm. Unlike the Puck 4, which offers more flexibility, it limits the user to two pre-set gradient factor options. However, it provides all essential functions for recreational safety with its ascent alerts.
Designed specifically for basic recreational diving, it does not support advanced training requiring changes between decompression stages.
For more information:
This is a strictly single-gas computer. It manages air and Nitrox mixtures ranging from 21% to 50% oxygen, but does not allow configuration of a second gas. It does not support Trimix or wireless air pressure transmitters.
The segmented display remains a simple design. It offers excellent contrast in sunlight, at the expense of the visual clarity found in higher-end models.
For more information:
The LCD screen uses "chip-on-glass" technology with 800 segments for display. The interface is controlled entirely via a single button, which requires some getting used to with the "short click" and "long click" system, especially if you are diving with thick neoprene gloves.
This is a standard format that ensures you will never be caught without power far from an electrical outlet on a cruise ship.
For more information:Powered by a replaceable CR2450 button battery, Mares claims a lifespan of approximately 100 dives. The monochrome LCD screen, which consumes very little power, contributes to this longevity.
This entry-level device's real strength lies in its connectivity: it communicates with your phone instantly, without requiring any additional accessories.
For more information:
The Bluetooth module is standard. It synchronizes directly with the Mares or SSI app to transfer your dive log (with a capacity of 100 dives) and perform software updates (firmware) easily.
It focuses on its primary mission of decompression calculation and leaves navigation to traditional analog instruments.
For more information:
It does not have an electronic compass. However, it includes a traditional depth gauge mode in addition to the Air and Nitrox modes.
Don't be fooled by its "Lite" designation, its housing can withstand pressure like a professional model.
For more information:
The housing is certified for water resistance up to 150 meters. A very appreciated detail: the straps can be easily removed to adapt it to an elastic attachment (bungee), which is very practical on a drysuit.
The ideal user: A beginner or recreational diver (Level 1) who wants a simple, affordable, and smartphone-connected piece of equipment.
Avoid if: You are a diver looking to quickly advance to accelerated multi-gas decompression (confirmed Nitrox), technical diving, or someone seeking the comfort of a large color screen.
The issue of after-sales service is crucial when investing in safety equipment. Regarding Mares, feedback is sometimes mixed. Some divers report quick exchanges within eight days, while others mention delays or some rigidity regarding shipping costs. The retailer plays a significant role in this process. Therefore, it's wise to go through a trusted store that can support your case if needed.
