Compact enough to fit in the palm of your hand, the new Vortex Solo 36mm R/T Tactical monocular delivers the optical performance required in low-light combat situations. Featuring generous eye relief and a large exit pupil, the Solo is built with a premium roof prism and fully multi-coated optics for a bright, clear view. Completely waterproof and nitrogen purged, with textured rubber armor and convenient carry clip, the Solo 36mm R/T is protected from the harshest elements, yet always ready for instant deployment. Special tactical features include a R/T ranging reticle based on Mil (mrad) measurements and a flared eyecup to block stray light.
