Carson's 10x42 XM HD Roof Prism Binocular is a 10x42 full-sized binocular combining phase coated prisms with new HD optical coating technology to ensure the brightest, sharpest images possible.  A rubberized armor coating makes this binocular rugged and shock proof.  The body is nitrogen purged and O-ring sealed rendering it waterproof and fogproof, and the long eye relief with twist down eyecups makes this binocular perfect for eyeglass wearers.  The 10x42 XM HD was tested against nearly every competing roof prism binocular below $1000 by an independent firm for its light transmissivity levels within the visible spectrum, and excelled within the class.
