On the go glassing has never been easier than with this little wonder of forward thinking engineering. FEATURES: Reverse porro prism design of the Vanquish uses high quality glass and fully multi coated optics to render images crisp and bright With a wide field of view that makes quick work of scanning any landscape HD Optical System: Optimized with select glass elements to deliver exceptional resolution, cut chromatic aberration, and provide outstanding color fidelity, edge-to-edge sharpness, and light transmission Fully Multi-Coated Lenses: Anti-reflective coatings on all air-to-glass surfaces provide increased light transmission for greater clarity and low-light performance Dielectric Prism Coatings: Multi-layer prism coatings provide bright, clear, color-accurate images Phase Correction: Coating on roof prism enhances resolution and contrast ArmorTek(R): Ultra-hard, scratch-resistant coating protects exterior lenses from scratches, oil and dir Rubber Armor: Provides a secure, non-slip grip, and durable external protection Argon Gas Purged: Gas purged and O-ring sealed for superior fogproof and waterproof performance in the most extreme conditions Waterproof: O-ring seals prevent moisture, dust and debris from penetrating the binocular for reliable performance in all environments Fogproof: Designed to withstand a wide range of temperatures Shockproof: Rugged construction withstands recoil and impact Tripod Adaptable: Allowing use on a tripod or car window mount. Tripod adapter may be required
