The 10x42 Spirit XF 1042 Binocular from Vanguard is a 10x 42mm roof binocular with a smart, tough and rugged looking design. With its cross-over black rubber supports, ridged and textured non-slip rubber armoring and open-bridge architecture, this roof binocular looks like it's ready to do tactical duty on a spaceship. But don't be fooled. This high performance optic is targeted for terrestrial operation. It has been nitrogen-charged providing fogproof and waterproof use on earth-based bodies of water and our atmospheric rain, drizzle or snow conditions.
The optical line-up is impressive. Fully multi coated optics providing brighter, higher-contrast images augmented by two coatings. Multiple-position twist-out eyecups and a smooth-motion diopter ring allow comfort customized viewing with or without sun or eyeglasses for extended viewing sessions. This is a tough looking binocular that can withstand tough conditions.
