The uni-body construction of the Night Owl Night Hawk night-vision scope contains two high-quality intensifier tubes that are preadjusted to give you optimal viewing results. This design also reduces the overall weight of the scope, making it only two pounds. You can safely use them with a temperature range of -22 F to 113 degrees F (-30 C to 45 degrees C). Its quick diopter adjustments, combined with the instant distance focus, ensure that these binoculars give you the quick focusing action you need for nocturnal wildlife observation. This compact, easy-to-use night vision scope has an integrated infrared illuminator and requires two AA batteries to operate. The protective lens covers are attached to the body.
