Leupold BX-1 McKenzie HD 10x50mm Binoculars Shadow Gray

The Leupold BX-1 McKenzie HD 10x50mm binoculars deliver professional-grade optical performance with enhanced light transmission for extended hunting sessions and outdoor observation. Built with Leupold's HD lens system and Twilight Max Light Management System, these roof prism binoculars provide exceptional clarity in challenging light conditions.

What Makes This Different

The HD lens system incorporates multiple anti-reflective coatings that increase light transmission to 92%, significantly outperforming standard coated optics that typically achieve 85-88% transmission. The 50mm objective lenses gather 25% more light than comparable 42mm models, extending usable viewing time into dawn and dusk periods. Leupold's Twilight Max technology optimizes the light spectrum specifically for low-light performance.

Key Features

• 10x magnification with 50mm objective lenses for superior light gathering
• HD lens system with multiple anti-reflective coatings for 92% light transmission
• Twilight Max Light Management System optimizes low-light viewing

Field testing demonstrates consistent edge-to-edge sharpness across the 341-foot field of view at 1,000 yards. The close focus distance of 6.5 feet makes these binoculars versatile for both distant observation and near-field detail work. Weather sealing withstands submersion to one meter and prevents internal fogging in temperature differentials up to 100 degrees Fahrenheit.
