Sporty binoculars provide focus free use and require no manual adjustment. The sophisticated optical system is based on the eye's natural ability to focus at a set point. All objects from that point and beyond are automatically in focus without additional work on the part of the eye muscles. The sporty binoculars will function from a near Focal point to Infinity. This binocular Series is ideal for fast moving events like auto racing, horse racing, and other sporting events.
