Sightron Japan Binoculars SV 10X42ED 10x Diameter 42mm Large Diameter Outdoor Field Observation Completely Waterproof SIB40-1013

This product is a high-end binocular that combines the technology that Sightron Japan has cultivated over many years of binocular development and pursues high optical performance without any compromise, with the motto of ``binoculars that can see clearly''. The objective lens uses a special low dispersion (ED) lens. It achieves clear, extremely sharp high resolution with no chromatic aberration. Although it is a roof type prism, it uses an Abbe-Koenig type prism that achieves total reflection on all reflective surfaces. All lenses and prisms are coated with high-quality full multi-coating, which is superior to conventional coatings. Of course, the performance of these binoculars increases as it gets darker, allowing you to see brighter and clearer images. Adopts center focus method and large metal focus ring. The large focus ring allows you to easily adjust the distance to your target. The long eye relief design also allows you to see every corner of your field of vision even when wearing glasses. Filling the inside of the main unit with dry nitrogen prevents internal fogging. It is safe for use outdoors in sudden rain or near water. The elastomer exterior makes it easy to handle even in cold regions and allows for a firm grip.
