Clear Viewing from First Light to Dusk

When you are working through timber or scanning open country, the BX-3 Alpine HD 10x42 gives you a broad area to work across while retaining clear detail through the image. Leupold's Elite Optical System is designed around dawn-to-dusk light transmission, glare reduction in harsh light and edge-to-edge clarity, while the 114 m field of view at 1000 m gives you plenty of ground in each scan.

Adjustable Fit and Tripod Support

The magnesium chassis weighs 641 g and is covered with rubber armouring for a positive grip. Interchangeable Form-Fit eyecups let you choose between different viewing profiles, including a low option designed for glasses and a winged option for blocking stray light. A built-in rotatable 1/4-20 tripod port provides a mounting point when you want a steadier glassing setup.

Guard-Ion hydrophobic coating helps shed water and dirt from the lens surfaces, while Leupold's waterproof and fogproof construction uses internal sealing and gas to help keep moisture out through changing temperatures and elevation.
