Wide 10-22x zoom magnification range provides wide views at low magnification, with the ability to make detailed observations of distant objects at high magnification. Large 50mm objective lenses improve light-gathering ability for bright and clear images, even in challenging conditions such as at dawn and dusk. Traditional Porro prism light path produces a rich depth of field, allowing the user to discern the relative distances between objects in the view. Ergonomically placed zoom lever allows user to adjust the zoom without removing binocular from the eyes with a simple movement of the thumb. Tripod adapter included for hands-free use to eliminate the vibrations/shakes and arm fatigue that are common when holding high-power optics
