Magnification zoom range and objective lens diameter combination is optimized for use in forested areas where light can be poor and conditions less than ideal; 2.4-12x magnification is ideal for close to mid-range use; Large 50mm objective provides the light-gathering ability required for use in low or challenging light-such as at dawn and dusk or under a heavy cloud cover or in dense fog; Versatile zoom range allows users to enjoy a wide field of view on low power to scan a large area then zoom in for proper identification and accurate shots; Anti-reflection index-matched SWAROTOP lens coatings are specifically formulated for the glass they are applied to-which minimizes light loss while reducing glare and improving contrast, color rendition, and clarity; Scratch-resistant SWARODUR coatings protect exterior lens surfaces; 46' field of view at 100 yards on 2.4x magnification, 9' at 12x power; Non-illuminated; Located on the second focal plane so reticle appears to stay the same size regardless of the magnification setting; Modified duplex crosshair design
