These Monarch 7 waterproof binoculars from Nikon are suitable for a wide range of outdoor activities and weigh less than 500g, making them the lightest in their class of high performance binoculars. They're waterproof, fog-free and are shielded in a protective rubber coating for shock resistance, which also gives a secure and comfortable grip. A lightweight body made of fibreglass-reinforced polycarbonate resin makes the binoculars easy to carry with you. Extra-low dispersion (ED) glass corrects chromatic aberrations. A dielectric high-reflective multilayer prism coating produces more natural colours and brighter, more truthful images. A phase correction coating gives high resolution images. Wide apparent field of view (60.7°). Long eye relief gives a clear field of view, even for those who wear glasses. Lenses and optics use only eco-glass optics which are free of lead and arsenic. Binoculars are waterproof up to 1m for up to 10 minutes, and fog-free with nitrogen gas and O-ring seals. Features turn-and-slide rubber eyecups. Rubber armouring for shock resistance and a firm, comfortable grip. Soft neck strap for comfort when using and carrying.
