FEATURES
An elite binocular delivering the low-light clarity and wide field of view hunters need to spot movement at dawn and dusk.
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 armour texture and interchangeable Form-Fit eyecups.
Like all Leupold binoculars, the BX-3 Alpine HD is waterproof, fogproof, and guaranteed for life.
HIGH-DEFINITION CLARITY Elite Low-Light Performance
RUGGED ARMOUR TEXTURE Protection & Grip in all Conditions
INTERCHANGEABLE FORM-FIT EYECUPS Easy to Swap and Clean
TRIPOD READY Built-In 1/4-20 Tripod Adapter Port
ELITE OPTICAL SYSTEM Offers excellent dawn-to-dusk light transmission for a bright image when it matters most, elite-level glare reduction in harsh light, and the resolution and clarity that diehard hunters and shooters demand.
EXTREME CLIMATE EXPOSURE We make sure our optics perform at the highest level by ensuring they will survive extreme temperature changes. Our binoculars are tested under the harshest conditions, so you can use them under the harshest conditions, without fail.
WATERPROOF + FOGPROOF From torrential downpours to crossing rivers, you’ll never have to worry about a Leupold binocular leaking or fogging up. Our proprietary gas blend and seals can withstand extreme temperatures, elevation changes, and shocks, so the internals of the optic stay moisture-free and crystal clear for life.
GUARANTEEED FOR LIFE Built for a lifetime of performance - if at any time your binocular doesn’t perform, we will repair or replace it for free - whether you're the original owner or not.
