These all weather models set a new performance standard. With one-touch Image Stabilizer technology, they instantly compensate for “binocular shake”. Large diameter 50mm front objective lenses accommodate a wide range of activities – from sports to astronomical observation. A multi-coated Ultra-low Dispersion (UD) lens element in each objective section delivers outstanding image contrast, sharpness and colour clarity. To accommodate eyeglass wearers, 15mm Long-Eye Relief provides greater viewing comfort, and the ergonomic design makes them very easy to hold. An optional anti-fog eyepiece prevents condensation and fogging in foul weather.
