The silver 10x24 Aculon T51 Binocular from Nikon is a compact optic designed for close to mid-range observations. At the core of the Aculon T51 series binocular are lead-and-arsenic-free Eco-Glass optics. This responsibly-sourced multicoated lens system is designed to transmit enhanced contrast and clarity. Complementing the multicoated Eco-Glass optics, a broad focus range equips this streamlined binocular for close-up sightseeing as well as viewing the stage from nosebleed seats. The 10x configuration of the Aculon T51 features an 8.2-foot minimum focus distance and a 5.3° angle of view. A stylish metallic silver finish, lightweight aluminum housing, and pocket-sized form factor make the Aculon T51 suitable for traveling, concert-going and any observation on the go.
