Configured with a powerful magnification and large objectives for maximum viewing distance to assist outdoor enthusiasts, birders, hunters, and sightseers, Leupold's gray colored 12x50 BX-4 Pro Guide HD Binocular is a great addition to any kit. The Pro Guide are engineered with lead-free high-transmittance calcium-fluoride glass elements, phase-corrected BAK4 roof prisms, and the proprietary Twilight Max HD lens coating system which is engineered to complement the optical properties of the glass to deliver crisp and clear high-contrast images with accurate color rendition and virtually zero distortion across its wide field of view. The Twilight Max system ensures maximum light transmission across the entire visual spectrum, especially in the upper blue/violet wavelength range to enhance low-light vision. Its wide 60° apparent angle of view helps to minimize the appearance of visible hand-shake that is common with high-power optics such as this.

Its open-bridge/dual-hinge design helps to reduce weight while providing more surface area for your hands to grip the optical tubes — improving grip security and stability. To withstand the rigors of the outdoors, the chassis is made of a lightweight and durable aluminum alloy wrapped in a protective gray-colored rubberized armor. Textured palm-pads improve grip security for sure-handling even in cold and wet weather, and a large textured focus wheel ensures precision adjustments even when wearing gloves. The optical tubes are nitrogen-filled and O-ring sealed to be waterproof and resistant to internal fogging when moving through extreme temperatures and environmental conditions.
