Uses ED glass lens for sharp and high contrast images: Compared to ordinary optical glass, it uses an ED (special low dispersion) glass lens with less refractive index changes from blue to red. By reducing chromatic aberration, you get the natural image that you see with the naked eye
(Bright and Clear with Phase Coat and Dielectric Multilayer Membrane) Daha prism is applied to correct phase differences, and the auxiliary prism is applied with an ultra-highly reflective dielectric membrane to reduce loss of light and produce bright, clear images. It also helps to improve resolution and contrast
(Fully Multi-Coating) Multi-coated (multi-layer coating) for all lens and prism surfaces to achieve high transmittance
(Twist up perimeter) The long eye relief design is over 0.6 inch (15 mm) eye relief. It does not get tired even when observing for long periods of time, and can also be worn with glasses to obtain a wide field of view
Waterproof Design: The waterproof design is safe for use in sudden rain or near water. Nitrogen gas is filled inside the body to prevent fogging inside the lens. Conforms to JISB7261 (ISO9022-8) in water depth equivalent to 3.2 ft (10 minutes) and IPX7 (10 minutes)
