Kaibab HD Binoculars deliver the power and superior optical quality hunters need to locate trophy animals at extreme distances. It starts with premium extra-low dispersion glass that delivers the ultimate in resolution and color fidelity, resulting in high-definition images. The lenses are index-matched for color correction across the visible spectrum, and enhanced with XR Plus full multi-coatings on all air-to-glass surfaces for peak light transmission and clarity that brings distant bulls right up close. And because hunting above the treeline is so demanding of your gear, Vortex outfitted the Kaibab with all the best performance features. All exterior lenses feature ArmorTek ultra-hard, scratch-resistant coatings to protect against scratches, oil and dirt.
