The Spirit XF 8420 Binocular from Vanguard competes with high-end binoculars for the amount of features that are included in this 8x 42mm roof design. Roof prisms offer a smaller, lighter, sleeker architecture with fewer internal parts. The fully coated optics are made with superior BAK4 glass as well as emerald coating to ensure vivid and natural shades of green.
Textured rubber armoring provides a secure and comfortable grip, as well as added shock-resistance. O-ring sealing and nitrogen charging furnish waterproof and fogproof protection making the Spirit XF suitable for all types of outdoor activities in any kind of weather. The open-bridge architecture is visually pleasing and adds to the lightweight of the binocular. Multiple-position twist-out eyecups and a smooth-motion diopter ring allow comfort customized viewing with or without sun or eyeglasses. This is a full-featured binocular at a popular price.
