Bushnell's green 8-24x25 Spectator Sport Zoom Binocular features a wide zoom range that allows you to enjoy a wide field of view when on the low magnification, then zoom in on a specific point for detailed observations at high power. A simple lever situated on the bridge controls the zoom, and just forward of the lever is a recessed focus wheel. Individual dioptric adjustments on each eye enable most users to precisely adjust the focus to their prescriptions for tack-sharp views. Twist-up eyecups make fine-tuning the eye relief fast and easy with or without eye wear. A clear case is included to help users move through security at sporting events, concerts, and events faster and easier.
