The reflector binoculars NRB 30x50 feature the highest magnification in the Yukon product line. The 30x magnification allows the binoculars to be used for long-distance observation. Application of Newtonian reflector technology permits the NRB 30x50 to estimate unequal distances between the target objects. For prolonged observation the use of a tripod is recommended. The binoculars are outfitted with ¼ inch tripod mount to attach the tripod adapter (included).
The binocular’s body and its controls (central focusing wheel, eyepieces) feature rugged rubber armored covering. External riffled coating and ergonomic shape of the body provide secure grip and comfortable operation. The use of this coating protects the body as from moisture and dust.
