20x80 M2080 Military Binoculars
Product Description
Their performance starts with the combination of powerful magnification and over-sized objectives. At 80mm the objectives draw in the copious amounts of light required for seeing in low light, or in heavy fog and cloud cover; while the 20x power brings distant subjects in close for detailed observations. The optics are fully multi-coated to maximize light transmission through the light path, with a wide angle of view to provide sweeping views despite the high power, while helping to minimize the discomfort often associated with using optics on rough or rolling seas. All of these features, when coupled with the traditional Porro prism light path, present the user with an immersive observational experienced defined by bright and clear high-contrast views and accurate color rendition.
Complementing the optical performance are construction details that allow the binoculars to withstand the rigors of the outdoors. These details begin with Steiner's Sport -Auto-Focusing System which allows the user to focus each eyepiece, just one time, and eliminates the need to refocus again regardless of how near or far the subject is - or if it is moving. The chassis is made of a lightweight and impact-resistant Makrolon polycarbonate material that is wrapped in an oil-, petroleum-, and chemical-resistant NBR synthetic rubber armor that offers improved grip security, especially in cold and wet weather. Their optical tubes are nitrogen-filled and O-ring sealed to be waterproof to a depth of 16 feet, and resistant to internal fogging when moving through extreme temperature changes and environmental conditions. Because of the challenges posed by hand-holding large and powerful optics, Steiner includes a tripod adapter that clamps anywhere along the center stabilizer bar to steady the view and relieve arm fatigue.
