UltraView binoculars combine fabulous light-gathering capability with the long eye relief and unsurpassed optical performance that have earned them their outstanding reputation. The eye relief of 22mm means eyeglass wearers can leave their glasses on and still take in the whole field of view. Just retract the twist-lock eyecups and you're in business. UltraViews have high-index BAK-4 glass prisms, with fully multi-coated eyepiece and objective lenses to facilitate maximum light transmission and image quality. Their precision-engineered, cast-metal alloy body stands up to rugged field use and is rubber armored for water resistance and a secure grip. Includes soft case, lens caps, and deluxe wide neck strap. Ten-year limited warranty. Made in Japan.
