Winchester Supreme Features The Winchester Supreme uses silver-coated phase correcting BAK4 roof prisms paired with wide band green objective and eyepiece coatings to maximize light transmission and boost contrast in low light conditions. Its 50mm objective lenses and 4.88mm exit pupil pull in a bright image even during the dawn and dusk hours when game is most active and the 6.1-degree field of view keeps a wide picture in frame for tracking moving targets. A center focus wheel with knurled adjustment knobs delivers smooth secure focusing and the -3/+3 diopter adjustment allows each eye to be dialed in individually for a sharp overall image. Hunters and bird watchers alike benefit from this level of optical clarity in a full-size glass. Built on a high performance PPS thermoplastic chassis the Supreme balances a lightweight feel with rigid rugged durability suited to years of field carry. The Nitrile NBR/PVC rubber armoring resists heat and oil exposure while providing dependable shock absorption if the binocular is dropped or bumped against gear. Twist-up eyecups let the shooter use the Supreme comfortably with or without eyeglasses and the sealed nitrogen-purged housing keeps moisture and fog out in any weather. The package includes lens covers a cleaning cloth a chest harness and a padded case giving hunters and outdoor enthusiasts everything needed to get into the field right away.
