We've taken everything that makes our Pocket Pro II design great and enhanced it to create the ProTimer, delivering one of the best values on the market. This upgraded timer now offers even more valuable practice session data through an intuitive, built-in user interface. With the ProTimer, you can easily collect and review all your shot data directly from the display, including a 50-shot string memory and hit factor scoring calculation to track your performance. Powered by a single 9V alkaline or lithium battery (not included), the ProTimer makes it easier than ever to refine your shooting skills and get the most out of every training session.
