Using cutting-edge optical technology, Sightmark® Solitude 7x36 XD Binoculars deliver stunning sharpness and contrast. Their XD (extra low dispersion) glass help correct optical color defects, caused when different light wavelengths do not converge at the same point after passing through optical glass. Featuring Bak-4 roof prisms, the Solitude 7x36 XD Binoculars yield an advanced, straight tube light system, achieving maximum light transmission and a compact design. The prisms and lenses are fully broadband multi-coated, improving efficiency at the entire range of the visible spectrum. The Solitude's 7x magnification provides crisp, clear short distance imaging for any outdoorsman wanting to explore their surroundings. With a smaller objective lens, the Solitude 7x36 XD Binoculars are ideal for travel and quick, on-the-go observation. Its magnesium bridge makes the unit lightweight, noncorrosive and durable. Built to withstand the harsh conditions of the outdoors, Sightmark's Solitude 7x36 XD Binoculars have a rubber-armored, nitrogen-filled and O-ring sealed body, making them waterproof, fog proof and dust proof. The twist-up, adjustable eye cups provide a comfortable, custom fit, helping to correct eye relief at any viewing position.
