Opticron's 8x50 Discovery WP PC Binoculars fuse image-enhancing optical technologies and ergonomic handling to create a set of glasses with bright and clear high-contrast images, especially in low-light conditions, that can stand up to the elements. They feature large objective lenses that enhance the Discovery's performance at dawn and dusk or areas with a thick canopy, and anti-reflective fully multicoated optics to maximize light transmission and enhance image contrast. Complementing the lens system are phase-corrected roof prisms that render lifelike colors and sharpness. Twist-up rubber eyecups and a long 21mm eye relief outfit the binoculars for a comfortable viewing experience even while wearing eyeglasses.

Complementing the optical performance is a light and durable magnesium alloy housing that is nitrogen-filled and o-ring sealed to perform in extreme humidity or temperature extremes and heavy rainfall without fogging. The build quality and optical performance, including an exceptional close viewing distance of just 4.9', make the Discovery a full-featured optic for close to long-range observations from dawn to dusk.
