When Mares launched its Puck dive computer on the market in 2008, a shock wave shook the field. It is an extremely intuitive nitrox dive computer, easy to use, with all the RGBM functionalities - at an extremely competitive price. It was not easy to improve the original design, but Mares was able to do it by adding an even larger display to a thinner design, then added progressive software and multi-gas management.
