The 10x42 Acadia binocular has the power you need when searching for critical details from a distance. Named after the first National Park east of the Mississipi River, the Leupold Acadia binocular combines the positive handling characteristics of a roof prism binocular with the performance and price of a Porro prism design. Fully multi-coated lenses enhance the light transmission which, in turn, provides a bright, crisp image.
