The Argos G2 10×42 UHD has a secure, ergonomic, and comfortable one-handed grip. They come with superior quality Advanced fully multi-coated lenses for sharp contrast, true color, and excellent light gathering capabilities. They also have Bak-4 prism glass featuring Extra-Low Dispersion lenses and our new ESP Dielectric coating and phase correction for color fidelity and sharpness. Argon gas purging makes the Argos binoculars waterproof and fog proof. A light weight magnesium alloy chassis reduces weight, taking strain off of your neck but makes it strong enough for the harshest environments.
