The red 10x21 Aculon T01 Binocular from Nikon is a compact optic designed for close to mid-range observations. At the core of the Aculon T01 series binocular is lead and arsenic-free Eco-Glass optics. This responsibly-sourced multicoated lens system is designed to transmit clear images with enhanced contrast. Nikon's Turn-and-Slide rubber eyecups have multiple click-stop settings that enable a comfortable viewing distance even while wearing eyeglasses. This configuration of the Aculon T01 features 10x magnification and a 10-foot minimum focus distance, equipping it for distant observations yet versatile enough to focus on close subjects when birding or sightseeing. The stylish red finish, lightweight 6.8 oz housing, and pocket-sized form factor make the Aculon T01 suitable for glassing on the go.
