The Swarovski CL Companion 10x30 Binocular 58248 features impressive optics that deliver smooth, high-contrast images. Swarovski's SWAROBRIGHT phase-correcting coatings applied to their premium roof prisms eliminate color fringing and aberrations for enhanced color fidelity and contrast, while their SWAROTOP coatings on the other optical surfaces maximize light transmission, transmit neutral and natural color fidelity, and improve contrast and clarity. The outer lens surfaces are further coated with Swarovski's SWARODUR coatings, which offer scratch resistance and allow oils, saps, and water to bead off. This not only helps to keep the surfaces clear, it makes cleaning them easier. This model comes with the Northern Lights accessory package, which includes a sheep's wool felt field bag and a leather strap.Swarovski CL Companion Features10X MagnificationCompact Roof PrismShort Bridge DesignSwarovski Optical CoatingsIn the BoxUrban Jungle Field Bag & StrapLens CoversEyepiece CoverWarranty CardSwarovski Demo ProductsSwarovski demo products have been slightly used for display or demonstrations by Swarovski during outdoor industry events.
