Leupold BX-3 Alpine HD 10x42mm Binocular

Whether you're hunting in the timber, open terrain, or anything in between, the BX-3 Alpine HD 10x42mm 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.
