The ZEISS Victory RF binocular laser rangefinder system incorporates a laser with an integrated real-time ballistics computer and on-board weather station. The consideration of all relevant factors coupled with user-based customization via the ZEISS Hunting App further ensures precisely placed shots from 10-2,500 yards away - time after time. The laser signals and atmospheric data received is computed within nano seconds to give you the appropriate, and accurate, shooting solution from a single press of a button.
