Optical PerformanceWide 8-18x zoom magnification range provides wide views at low magnification, with the ability to make detailed observations of distant objects at high magnificationLarge 42mm objective lenses improve light-gathering ability for bright and clear images, even in challenging conditions such as at dawn and duskTraditional Porro prism light path produces a rich depth of field, allowing the user to discern the relative distances between objects in the viewHigh refractive index BAK4 prisms deliver a round exit pupil and a crisp and clear image with limited edge distortionAspherical eyepiece lenses correct spherical aberration to produce clear and crisp images, with reduced edge distortion and astigmatismAnti-reflection multi-coated optics produce neutral and accurate color fidelity and improve contrast and image brightness199-foot field of view at 1000 yards, on 10x power
