Straddling the line between compact and full-sized models, the 8x30 X-Trail All-Metal Field Binoculars are built using traditional Porro prisms that offer a rich depth field and anti-reflection fully coated lenses to enhance light transmission for accurate color representation and improved contrast. Complementing these features are moderate magnification and objectives, and a lens diameter that allows these binoculars to be highly portable and easy to use, but with a wide 60° field of view. This generous field of view allows you to take in wide swaths of the landscape and immerse yourself in wonders of the world. The aluminum chassis has a textured exterior that provides a solid slip-resistant grip, with the natural ergonomic design for which Porro prisms are known, to make it comfortable and balanced in the hand. A large center focusing wheel and right-eye diopter help you bring your subjects into crisp focus, with fold-down rubber eye cups for easy use whether you wear eyeglass, sunglasses, or no glasses.
