     Designed for both astronomical and terrestrial use, the Pentax 20x60 SP WP Binoculars can be relied on with confidence in all weather and conditions. The large oversized 60mm objectives are fully multicoated to reduce reflection and maximize light transmission through the entire optical path. Utilizing the traditional porro prism configuration gives scenes a rich depth of view for an immersive observation experience and provides a comfortable feel in the hand with a lot of surface area to maintain a sure grip. The large objectives and coatings maximize the amount of light getting to the user's eyes for exceptional low-light capabilities.
