The Zeiss 3x12 T Monocular is an exceptionally compact, high-performance optical tool that functions as both a long-range pocket telescope and a high-magnification macro loupe. Measuring only 2.3 inches and weighing a mere 1.9 ounces, it features premium achromatic lenses with T multi-layer coatings* to ensure maximum light transmission and image clarity. While providing 3x magnification for distant observation, its standout feature is a remarkably short 8-inch close-focus distance, allowing it to serve as a 5x magnifying glass for inspecting fine details on maps, nature, or technical components. An Open Box unit typically represents a discounted floor model or return, offering the same high-contrast Schmidt-Pechan prism system as a factory-sealed unit.
