The LEICA DUOVID 8 +12 x 42 and 10 +15 x 50 are the only premium performance binoculars with two magnifications. No matter what the situation, whether it is over long distances or during critical lowlight conditions, the Leica Duovid adapts to it perfectly. The lower magnification (8 x with the 42 Duovid or 10 x with the 50) allows for shake-free viewing and a large field of view. By switching to the higher magnification (12 x or 15 x respectively) one achieves greater detail recognition. In contrast to monocular add-on power boosters, a binocular booster is already integrated in the Duovid –lightweight, easy to operate and with a large field of view. Both models are well balanced and feature an outstanding ergonomic design, thereby allowing for virtually shake-free viewing, even at high magnification. Other technical innovations, such as the Leica HighLux-System HLS™ and the Automatic Diopter Compensation ADC™ when switching between powers, make the Duovid a unique and versatile instrument.
