Designed for enhanced performance over a broad range of uses, including hunting and wildlife observation in open country and mountain terrain, forestry, wildlife management or boating. All feature a 10-year limited warranty; rainproof construction, and Steiner?s 20-yards-to-infinity Sports Auto-Focus system. An excellent choice for those who need extra power and brightness. The large, 50-mm objective lenses gather more light, and present a larger image to the user, yielding a brighter view and greater stability than binoculars with smaller objective lenses. The 10 x 50?s power, brightness and great depth-of-field focusing make this an excellent choice for spotting antelope, elk, or caribou.
