The 10X42 in Bushnell's Forge binocular line defines clarity. The Forge Binocular features Bushnell's newest and best protective lens coating, EXO Barrier Protection to ensure your lens are resistant to water, oil, fog, dust, and debris. Adding to this protection Forge binoculars feature IPX7 Waterproof Construction that allows your optics to stay dry inside for up to 30 minutes when immersed in 3 ft of water and are Nitrogen Purged to prevent fog. The Forge Series binoculars use Multi-Coated lenses that include Ultra Wide Band, Dielectric Prism, and PC-3 Prism Coatings that ensures optimal resolution and contrast even in low-light situations. The extra-low dispersion ED Prime glass also allows the Forge binocular to deliver superior color while preventing chromatic aberration so no detail goes unnoticed.
