The YF 8x30 Binocular (Black) from Kowa Sporting Optics is a porro prism binocular with a stylish exterior and an optically excellent interior. Smooth and sleek with strategically placed indentations in the rubber armoring, this glass delivers a secure and firm grip. It has a closed hinged bridge with an eye-catching red line at the intersection of the bridge's point-of-contact. Fully multi-coated, highly reflective coated and phase coated, these optics deliver crisp, clear, contrasted images with real color fidelity. With an eye to keeping the weight down, the engineers at BSA have not sacrificed the nitrogen gas filled fogproofing and waterproofing. This is a wide-angle glass with the ability to scan an exceptional field of vision. Rubber armoring provides a secure and comfortable grip, as well as added shock-resistance. Twist-up eyecups customize the viewer's personal preference with or without eye or sunglasses. The YF 8x30 binocular is a nice looking binocular with the optical features that will be appreciated in any venue; hunting, hiking, birding or sporting events.
