Leupold BX-3 Alpine HD Features The Leupold BX-3 Alpine HD is built around Leupold s Elite Optical System engineered to maximize light transmission and deliver edge-to-edge clarity along with a wider field of view spanning 342 feet at 1 000 yards. Guard-Ion lens coating sheds water oil and dust while improving light transmission for brighter images particularly valuable during the low light hours of early morning and late evening when game is most active. A 42mm objective lens paired with a 4.1mm exit pupil keeps the image bright even as available light fades. The binocular s 10x magnification offers enough reach to break down distant terrain and confirm details on game before closing the distance. A fully redesigned magnesium chassis keeps the Leupold BX-3 Alpine HD s weight to just 22.6 ounces while improving durability and ergonomics over earlier Leupold binocular designs. Interchangeable Form-Fit eyecups let users customize the fit for eyeglass wearers or those who prefer direct eye contact with the ocular lens and an improved armor texture provides secure grip in wet or gloved conditions. A built in 1/4-20 tripod adapter allows the binocular to mount for extended glassing sessions without hand fatigue. Fully waterproof and fogproof and backed by Leupold s lifetime guarantee this binocular is built for hunters who need dependable performance trip after trip.
