8x magnification , 43mm objective lenses , BAK4 roof prism optical path. Anti-reflection fully multi-coated optics ,Extra-low dispersion (ED) glass reduces chromatic aberration for sharper images with accurate color,Phase-corrected prisms produce high-contrast images with true color rendition,Hybrid aspherical lens elements correct for spherical aberrations to reduce distortion at the edges of the lenses and correct for astigmatism that can prevent sharp focusing. 330.8' field of view at 1000 yards ,50 degree angle of view.
Closed-bridge configuration,Large knurled center focus wheel,Right eye diopter adjustment,22mm eye relief, 5.4mm exit pupil,Twist-up eyecups for use with or without eyewear,Tripod mountable with optional adapter.
Lightweight and durable magnesium-alloy housing,Rubberized armoring protects against impacts and provides slip-resistant grip,Nitrogen-filled fogproof and submersible to 3.3' (1m),Internal focusing system helps to maintain waterproof seals,Dust/water/grease-repellent coatings keep the optical surfaces clean.
