The 10 x 42 BGA Monocular from Opticron combines a roof prism optical path, fully multi-coated optics, an internal focus system, and wide band focusing to produce a sharp, compact, easy to use and durable monocular. To withstand the rigors of outdoor use, its nitrogen-filled housing is fogproof and submersible to 9.8', allowing it to be used in all weather and conditions. A long eye relief eyepiece and twist-up eyecup provide a full field of view with or without eye wear, and the short 6.6' minimum focus distance lets users make detailed observations of insects, flora and fauna. This pocket-sized monocular measures just over 5" long and weighs a mere 2.4oz.
