Similar to its 42mm counterpart, the BX®-4 Pro Guide® HD Gen 2 10x50mm is a versatile optic for backcountry hunters. However, its 50mm objectives go the extra mile, collecting even more light for improved long-range identification. This upgraded version of our best-selling binocular uses high-quality glass and improved lens coatings to deliver the resolution, clarity, and glare reduction diehard hunters and shooters demand—no matter the time of day, you’ll be able to conquer the challenges of harsh light and bright reflections. Along with its outstanding optical system, the BX-4 Pro Guide HD Gen 2 includes interchangeable Form-Fit eyecups that’ll keep your eyes fresh through hours of hillside glassing.
