Developed to give hunters and birders a slightly higher magnification over standard 8x optics while preserving a wide-angle field of view, long eye relief, and limiting visible hand-shake common in higher power glasses, Swarovski 8.5A-42 EL Binoculars feature a high-transmission optical path, legendary Swarovski optical coatings, and a weather-sealed magnesium-alloy housing that delivers exceptional performance with the ability to withstand extreme conditions.Swarovski Demo ProductsSwarovski demo products have been slightly used for display or demonstrations by Swarovski during outdoor industry events.
