The Mares Puck 4 redefines what divers can expect from an entry-level dive computer. Combining simplicity with advanced technology, it ensures safe, customizable, and effortless dive management.

At its core, the Bühlmann ZH-L16C algorithm with adjustable gradient factors allows you to personalize decompression profiles for maximum safety and comfort. With air, nitrox, and bottom timer modes, as well as multigas capability (up to three gases), the Puck 4 adapts to any dive scenario.

Its 800-segment crystal-clear display ensures instant readability underwater, while intuitive single-button navigation makes operation seamless. Safety and planning are enhanced with a decompression dive planner, ascent rate indicator, and a functional bottom timer featuring a resettable average depth and stopwatch.

The digital logbook stores up to 100 dives with detailed graphs accessible via the Mares app, thanks to integrated Bluetooth connectivity. Divers can keep firmware up-to-date effortlessly and analyze dives directly from their smartphone.

Practical details such as adaptable straps, Mission Console compatibility, and a user-replaceable CR2450 battery (lasting up to 100 dives) make the Puck 4 a reliable, long-term companion. Built with mineral glass for durability and designed to meet the needs of both new and seasoned divers, it is your perfect underwater partner.
