The overall concept of the new Geovid HD-B brings about a revolution in rangefinding. Unique to these rangefinding binoculars is the supreme optical performance of their Perger Porro prism system, the optimised ergonomics of their bridge construction, and the additional integration of an extremely high-performance laser rangefinder with a multifunction ballistic computer. The Geovid HD-B accesses an internal database with ballistic curves for practically all standard calibre ammunition. In addition, users can upload their own specific parameters for hand-loaded or special ammunition from a microSD memory card. The newly developed ABC ballistic function (Advanced Ballistic Compensation) allows hunters to determine the point of aim much more easily and with greater precision than ever before. In fractions of a second, hunters can read off the precise parameters they need for their particular reticle or click adjustment. And all this taking the ammunition specifics, angle, temperature and barometric pressure into account.
