The Zeiss 3x12B Tripler Monocular without Adapter is a compact, multi-purpose optic that requires an adapter ring to connect the monocular to the eyepiece of select Victory FL / RF series binoculars. When not using the adapter to triple the magnification of your glasses, this monocular's 8-inch minimum focus distance and fully multi-coated lens system make it a premium-quality pocket-sized magnifying glass. Zeiss configured the 3x12B Mono with glass to match its functionality; it features achromatic lenses that produce detail-rich, color faithful images. Multiple layers of Zeiss' T* anti-reflective lens coating complement the color fidelity of the glass and enhance the contrast and sharpness of the transmitted view. Included with the monocular is a carrying strap and leather carrying case.
