Whether you&';re hunting in the timber, open terrain, or anything in between, the BX-3 Alpine HD 12x50mm delivers a clear advantage when it matters most. It&';s built for the hunters who rely on their eyes to spot movement, break down terrain, and stay engaged. Built around our Elite Optical System, the BX-3 Alpine HD series is designed to maximize light transmission, deliver edge-to-edge clarity, and provide a wider field of view. That means brighter images in low light, sharper detail across the entire image, and more ground covered with every scan. It&&';;s fully redesigned magnesium chassis keeps weight down while delivering durability and enhanced ergonomics-including an improved armor texture and interchangeable Form-Fit eyecups. Like all Leupold binoculars, the BX-3 Alpine HD is waterproof, fogproof, and guaranteed for life.
