Optical Features:

• XD Lens Elements: Extra-low dispersion (XD) glass increases resolution and color fidelity, resulting in crisp, sharp images.
• XR Fully Multi-coated optics: Proprietary coatings increase light transmission with multiple anti-reflective coatings on all air-to-glass surfaces.
• Second focal plane reticle: Scale of reticle maintains the same ideally-sized appearance. Listed reticle subtensions used for estimating range, holdover and wind drift correction are accurate at the highest magnification.

Construction Features: 

• Tube Size: 1 inch diameter tube offers a versatile blend of adjustment, size and weight for a wide variety of shooting applications.
• Single-piece tube: Maximizes alignment for improved accuracy and optimum visual performance, as well as ensures strength and waterproofness.
• Aircraft-grade aluminum: Constructed from a solid block of aircraft-grade aluminum for strength and rigidity.
• Waterproof: O-ring seals prevent moisture, dust and debris from penetrating the binocular for reliable performance in all environments.
• Fogproof: Argon gas purging prevents internal fogging over a wide range of temperatures.
• Shockproof: Rugged construction withstands recoil and impact.
• Hard anodized finish: Highly durable hard-coat anodization provides a low-glare matte surface and helps camouflage the shooter's position.
