The black 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 are lead-and-arsenic-free Eco-Glass elements. 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 positions 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, making this stylish binocular ready for distant observations while sightseeing and versatile enough to focus on nearby subjects when birding. The lightweight housing and pocket-sized form factor make the Aculon T01 suitable for glassing on the go. The 10x21 Aculon T01 binocular comes in clamshell packaging.
