Featuring an all new user-interface, AB Quantum™ includes a host of new tools and features that will enable shooters and hunters to be more successful in the field. AB Quantum™ creates a new paradigm for ballistic solvers and integration with Bluetooth®-enabled devices. With a host of new features, the platform is designed to save time and add performance for users of all skill levels.
