Opticron's 10x42 Oregon 4 PC Oasis Monocular features a phase-corrected BAK4 roof prism, large objective lens, and anti-reflection fully multicoated optics to give you a versatile and capable optic that produces bright and clear high-contrast images with accurate color rendition from dawn to dusk. The high magnification and large objective allows you to observe at a long distance without giving your position away. Its wide angle of view reveals a large observation area while minimizing the appearance of the distracting hand shake that is common when holding high-power optics such as this. The combination of optics, magnification, and viewing angle makes this version of the Oregon 4 PC Oasis ideally suited for most outdoor activities from hiking, to birding, to sightseeing.
