Pairing a tested optical system with efficient functionality, the 10x42 Natura BGA Binocular from Opticron features fully multicoated optics along with phase-corrected roof prisms for maintained sharpness and color accuracy. Furthermore, a 64-layer Oasis coating has also been applied to the prisms in order to maintain 99% or greater light transmission with minimized reflections for increased clarity and contrast. When coupled with the 10x magnification, this versatile binocular is ideally suited for general and distant viewing applications.
A textured rubber armoring offers enhanced durability and the housing has been nitrogen-purged to resist fog and render the binocular waterproof up to 10'. The body's design is double hinged for a more compact profile, which also offers exacting balance while holding. Focusing down to 8.9' is possible using the center wheel, which also adjusts diopter settings, and quick half-turn focusing between 10' and infinity is possible for easier tracking of moving subjects.
