Nikon has a complete line of optics Nikon built their MONARCH HG Binoculars around extra-low-dispersion (ED) glass and added multilayer coatings to all lenses and prisms, plus a dielectric high-reflective multilayer coating to the roof prisms to ensure exceptional clarity at all huntable hours. Up to 92% light transmission, true-to-life color fidelity and a phase-correction prism coating that enhances resolution and contrast give you the ability to pick apart a distant hillside at first or last light. Lightweight, compact die-cast magnesium-alloy construction delivers the toughness to go anywhere without weighing you down. Rubber grip panels ensure sure handling in all sorts of weather. A wide interpupilary distance adjustment ensures a perfect fit for your eyes, while a locking diopter keeps them set just the way you want. Long eye relief and twist-up eyecups. Scratch-resistant lens coatings. Nitrogen filled to resist water pressure and prevent fogging up, even in low-pressure, high-altitude environments. Minimum focus distance of just 65 ft. lets you scan thick brush near your stand. Backed by Nikons No-Fault Repair/Replacement policy and a limited lifetime warranty.
