These are the binoculars designed for magnification of subjects as near as 18". Unlike traditional models that use two-barrel construction, the objective lenses of these binoculars are mounted together in the same barrel, moving in tandem as the user adjusts focus. As a result, they allow the viewer to get close enough to discern the chitinous scales of a butterfly wing or the grains of pollen tucked into a honeybee's legs. the 8.5X magnification delivers crisp long-distance viewing as well, with a 344' field of view at 1,000 yards. Multi-coated optics block ultraviolet rays while heightening contrast for clear viewing. The tough rubber exterior and light weight make the binoculars suitable for any birdwatcher's field work. Includes case and strap. 3" H x 5" W x 5 1/2" L. (10 oz.)
