Dunk them, douse them, get them wet. The PENTAX UCF WP series of binoculars aren't afraid of a little water. Featuring nitrogen-filled waterproof (JIS Class 6) construction and a unibody design, these hardy binoculars are durable enough to stand up to even the wettest weather conditions. Available in two magnifications, the PENTAX UCF WP line features high-refraction BaK4 glass prisms for superior viewing, aspherical eyepiece lens elements for edge-to-edge sharpness, and fully multi-coated optical elements for improved light transmission and decreased glare. Compact, lightweight, and durable, the PENTAX UCF WP series are the ideal choice for use on or around water.
