The overall concept of the new Geovid HD-B 42 and Geovid HD-B 56 brings about a revolution in rangefinding. Unique to these rangefinding binoculars is the supreme optical performance of their patented 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 42 and HD-B 56 accesses an internal database with ballistic curves for practically all standard ammunition. In addition, users can upload their own specific parameters for hand-loaded or special ammunition from a microSD memory card.
