Full review: Mares Puck Pro

The Mares Puck Pro is a dependable, easy-to-read dive computer designed for divers who want reliable performance without unnecessary complexity. Housed in a rugged, oversized case, it features a large, high-contrast display that remains legible even in low visibility or murky water conditions. The intuitive single-button interface allows divers to navigate through menus and settings with minimal fuss, making it an excellent choice for both new divers still building confidence underwater and experienced divers who prefer straightforward functionality over a cluttered array of features. Its wrist-mounted design, complete with an adjustable strap, ensures a comfortable and secure fit over a wetsuit or drysuit sleeve.

At the core of the Puck Pro is the Mares-Wienke RGBM (Reduced Gradient Bubble Model) algorithm, which calculates decompression information with a strong safety margin, making it suitable for recreational air and nitrox diving. The computer supports up to three gas mixes, giving divers flexibility when diving with enriched air blends. It tracks essential data such as depth, dive time, ascent rate, and no-fly time, while also offering a visual and audible alarm system to alert divers to rapid ascents or missed safety stops. The backlit display and user-replaceable battery add practical convenience, eliminating the need for costly servicing just to swap out a depleted battery.

Built to withstand the rigors of repeated dives, the Puck Pro is water-resistant to significant depths and constructed from durable materials that resist scratches and impacts common in dive travel and boat diving. Its logbook function allows divers to review past dives, tracking key metrics for training progression or simply reminiscing about a memorable reef exploration. Compact enough to pack easily yet robust enough for demanding dive conditions, the Mares Puck Pro strikes a balance between affordability and functionality, making it a popular choice among dive schools, rental fleets, and individual divers looking for a no-nonsense, trustworthy companion beneath the waves.
