When daylight dims and the shadows deepen, the HD (High-Density) extra-low dispersion glass of the Viper HD 10x42 Roof Prism Binocular from Vortex Optics goes to work for you. Rivaling higher-priced European binoculars, the HD glass, XR coatings, ArmorTek protection and phase-corrected prisms deliver extra-high resolution and increased light transmittance - rendering brighter views than one would expect from binoculars in this class.
Vortex Optics knows there will be times when it's just plain hard to keep a handle on things that's why the Vipers feature rubber armor, sealed O-rings and Argon gas purging for years of exceptional viewing. Let it rain. Let it snow. Let the wind blow up a dust storm. Nothing gets past the Viper. These binoculars are made to be dust proof, fog proof and waterproof. Tripod adaptable with a large center focus wheel.
