Vortex Viper 8x28 R/T Tactical Binocular [VOV828RT]
The Viper R/T tactical binocular combines award-winning optics and required military features to create a tough, durable roof prism binocular-reliable in the worst conditions. XD (extra-low dispersion glass) objective lenses further enhance resolution and deliver the true-to-life color accuracy so essential for identifying targets. Soldiers and hunters can range objects of known dimension with the R/T Ranging reticle, which features four human silhouettes to serve as a secondary ranging aid.
