Designed with large objectives and a wide exit pupil, Bushnell's green 10x50 Trophy Xtreme Binocularis an optic with enhanced low-light capabilities versus optics with smaller objectives. To further boost its low-light abilities are phase-corrected BAK4 roof prisms and anti-reflection fully multi-coated optics that produce bright and clear high-contrast images with accurate color rendition from dawn to dusk. The combination of optics and objectives make the Trophy Xtreme ideally suited for most outdoor activities from hunting, to birding, to sporting events.
