The ZEISS Victory RF combines the premium German craftsmanship and superior optical quality you've come to expect with a built-in rangefinder and ballistic computer to create the ultimate hunting Binocular. As with all Victory Series Binoculars, the Victory RF features ED glass that produces 90% to-the-eye light transmission for excellent target resolution and exceptional clarity in all light conditions-even twilight. And since deer move at dusk, being able to pick out tines in the dying daylight gives you a huge advantage. The T* 6-layer light transmission coating guarantees maximum color rendition and image brightness-so the views are always vivid, colorful and true to life. And because the weather isn't always ideal, ZEISS outfitted the Victory RF with their innovative LotuTec coating, which enables a clear and unhindered view in all weather conditions, rain included. But it's the built-in rangefinding and ballistics capabilities that set the RF apart. The rangefinder determines the precise target distance up to a maximum range of 2,500 yards, while the on-board ballistics computer and weather station send precise shot info and BDC with the single press of a button. Even better, the rangefinder system sends the info directly to the ZEISS Hunting App via Bluetooth. Every measurement takes the physical and environmental factors, such as temperature and air pressure, into account when making the calculation-so you can count on precision accuracy in addition to premier optical quality.
