These new binoculars offer the premium viewing of all Swarovski binoculars in a waterproof, dustproof and impact-resistant package. It has a rugged magnesium-alloy frame that is strong yet light, and the unique wrap-around grip lets you use them with one hand. The roof prism is SWAROBRIGHT® p-coated which ensures a degree of reflection of 99.5% over the entire width of the light spectrum. SWAROTOP® and SWARODUR® multi-layer coatings on all lens surfaces cut light reflection for extra-sharp viewing and detail. The patented three-lens objective maximizes light transmission. The diopter adjustment is integrated into the focusing wheel. A wide angle ocular allows an extra-large field of view, even when wearing glasses. These binoculars have a focus as close as 6.6-feet, making them ideal for close and detailed viewing. Limited Lifetime Warranty.
