The Pentax 10x30 A-Series AP WP Binocular delivers bright clear images without being over sized or cumbersome owing to its anti-reflection fully multicoated 30mm objectives which maximize light transmission to produce the brightest views possible. Utilizing traditional porro prisms produce scenes with a rich depth of view over similarly sized roof prisms with the added benefit of a larger surface area to give it a comfortable feel in the hand.

In order to cut weight, the housing is made of corrosion and impact-resistant fiberglass reinforced polycarbonate polymer. The material is also temperature-resistant allowing for its use in extreme climates while reducing expansion and contraction wide temperature swings can cause which can make the optical components move out of collimation over time. Its optical tubes are nitrogen-filled and O-ring sealed so they can are submersible to 3.3, as well as fogproof in all weather conditions.
