Vortex Diamondback 20-60x80 Angled Body Spotting Scope - The Diamondback optics guarantee a bright image throughout the magnification range and, as true to all Diamondback optics, the rugged construction stands up to rough use in the field. Multi-layer coatings provide the clearest, brightest, most color-accurate images possible. Vortex proprietary XR anti-reflective coatings, fully multi-coated on all air-to-glass lens surfaces, increase light transmission for maximum brightness. The angled body design is valued for allowing an overall lower mounting height which maximizes stability in wind, offers greater comfort when glassing for extended periods, and permits the use of a smaller, lighter tripod. Nitrogen gas purging delivers fogproof, waterproof performance.
