The 8x42 Spirit XF 8420 Binocular from Vanguard competes with high-end binoculars for the amount of features that are included in this 8x42mm roof design. Roof prisms offer a smaller, lighter, sleeker architecture with fewer internal parts. The fully mult-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 light weight of the binocular. Multiple-position twist-up eyecups and a smooth-motion diopter ring allow comfortable customized viewing with or without sunglasses or eyeglasses. This is a full-featured binocular at a popular price.
