When Mares introduced the Puck dive computer on the market in 2008, it sent a shockwave rippling through the industry: a super intuitive, easy to use, full-featured RGBM nitrox computer at an extremely competitive price. Now they are doing it again. Though improving on the original concept was not easy, Mares did so by implementing a larger display in a slimmer design, then added upgradeable firmware and multigas capability. All the bells and whistles, no unnecessary frills.Puck Pro is the computer that can accompany you through years and years of diving adventures.
