The Viper HD 20-60x80 Spotting Scope from Vortex has proprietary XR anti-reflective coatings and HD (High Density) extra-low dispersion glass for increased resolution and color fidelity. Fully multicoated on all air-to-glass lens surfaces, the light transmission is increased for greater brightness. The Porro prism construction offers excellent image quality and performance in a traditional design. Meeting challenging conditions with confidence is accomplished by the argon gas purging which ensures fogproof and waterproof performance of this all-weather scope. The waterproof optics are sealed with o-rings to prevent moisture, dust, and debris from getting inside the spotting scope. ArmorTek ultra-hard, scratch-resistant coating protects exterior lenses from scratches, oil and dirt. Complete with a zoom eyepiece, built-in sunshade, rotating tripod mount, and case, this is a spotting scope to own.
The versatile magnification of the Viper spotting scope allows viewing at a wide field-of-view at lower power, then zooming in on distant details. The magnification of the spotting scope is changed by simply turning the magnification adjustment ring. A straight body design is valued for quick target acquisition and ease-of-use with car window mounts. A twist up and down eyecup provides comfortable viewing with or without eyeglasses or sunglasses so that the full field of view can be observed. Twist the eyecup down when viewing with eyeglasses or sunglasses and twist up when viewing without glasses.
The dual focus feature allows for maximum focusing precision with both coarse and fine focus adjustments. After setting the magnification, you can adjust the fine focus. This does more than allow you to see critical details, it also ensures fatigue-free viewing. When you change the magnification, some refocusing is usually required. The coarse and fine adjustments is handled with just the tip of a finger: slowly turn the coarse focus dial until the subject is nearly in focus and then turn the fine focus dial to pick out the details.
The sunshade reduces glare and shields the objective lens from rain and snow. Extend this fitted shade to effectively block out disturbing stray light. The tripod foot attaches to any tripod or car window mount that uses 1/4 x 20 screw threads.
A built-in Picatinny rail can be used to easily attach red dot type sights.
