Now the PRO features LEICA introduced with the GEOVID PRO 32 models are available in 42mm and 56mm models as well, creating the most extensive line of professional-grade laser ringefinding binoculars available. The unrivaled combination of optical quality, unique ergonomic design, sophisticated Applied Ballistics ballistic calculation, and the fastest, most reliable range measurements are the advantages that make our GEOVID PRO models the revolutionary and leading pioneer in their class. Out of the box, Geovid PROs are equipped with Applied Ballistics UltraLite, allowing the user to range a target and receive both ballistic drop and wind corrections out to 875 yards as soon as your rifle's ballistics are programmed into the free and easy-to-use Leica Ballisitcs app and Leica Pro Track, which allows you to mark a target location via 3 (external) GPS solutions: BaseMap hunting app, GoogleMaps, or Leica's own ProTrack system (accessible thorugh the Leica Ballistics App. Your Geovid PRO's ballistic system can also be upgraded to Applied Ballistics Elite via an in-app upgrade for 150. This allows the Geovid PRO to provide ballistics drop and wind corrections as far as the PRO can range via advanced ballistics corrections available only in Applied Ballistics Elite such as: AB's radar generated custom drag models, spin drift correction, aerodynamic jump and coreolis effect. Specifically, the 10x42 Geovid PRO provides increased detail recognition at distance because of its 10x magnification, yet maintains very good low light performance and ample field of view, all in a familiar and easy to carry 42mm form factor.
