The blue 8x21 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 8x 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 lightweight 6.8 oz housing and pocket-sized form factor make the Aculon T01 suitable for glassing on the go.
