Brunton, a mining engineer, invented a pocket-sized precision compass. He developed and sold compact, high-precision compasses, replacing the time-consuming and difficult-to-use outdoor equipment of the time. Today, it's a top brand for compasses and optical instruments. Brunton's monoculars are well-regarded in the field of optics and precision instruments. The prism, a key component of the monocular, uses Bak4, an optical material with high reflectivity, providing a bright field of view, clear subjects, and a sharp image. Its compact size and light weight fit in your bag or pocket without getting in the way, and it's easy to adjust the focus with one hand when in use, making it very user-friendly. The rubber-covered body is non-slip and easy to hold, and it comes with a case with a belt holder and a strap to prevent accidental drops during trekking or sports viewing. This is the same type of monocular used by Jack Bauer in the American drama "24."
