Its 10x magnification and 40 mm objective lenses provide a detailed view of action at distance, while the 305-ft field of view at 1,000 yards gives viewers useful coverage across a field, track, or stadium.
The optical system combines BaK-4 roof prisms with multi-coated optics and a 4 mm exit pupil. Bushnell’s PermaFocus technology is designed to keep distant subjects in focus without requiring constant adjustment, which is particularly useful when following fast-moving action during a game or event.
