The 30x Wide Angle Ranging Eyepiece from Vortex only fits the 85mm Razor HD spotting scope and integrates a practical level of magnification with a MOA reticle for precision target-range estimation and shot correction. The eyepiece is O-ring sealed and argon-purged to be waterproof and fog proof.
All optical surfaces are fully multicoated with Vortex's XR anti-reflective coatings. The lenses are made of high-density extra-low dispersion glass. This combination of HD EL lenses with the XR coatings produces clear and bright images without distortion, even in low-light conditions. The ArmorTek scratch-resistant coatings protect the exterior lens surfaces from scratches, dirt, and oil.
