Image Quality

Leupold BX-4 Pro Guide HD 10×50 binocular is famous for its peculiar light transmission, providing superior quality images even in low lights with the Elite Optical System.

The premium technology helps to reduce glare in harsh light instead of enhancing the edge-to-edge resolution and clarity. Thus, the hunters can observe their targets from dawn till dusk.

Likewise, the Diamond Coat2 technology coated on the exterior lens surface helps improve light transmission. Due to the lens coating, the binocular offers perfect contrast and brightness. Similarly, the fully multi-coated system ensures accurate color reproduction.

The Guard-ion helps provide maintenance-free crisp images even with external challenges. It is a hydrophobic lens coating that protects the optics from water, dirt, and other factors. It not only optimizes image quality but also increases durability.

The binocular prevents light transmission interference with the phase-correction coated roof prism, thus enhancing its sharpness. Further, the broad field of vision lets you see even in difficult areas with reliable clarity. Also, the 10x zoom works well in wide spaces.

Moreover, the binocular combines some of the powerful features making it a great companion in every condition.
