Tasco Futura LE Black/Gray Binoculars with Carry Case

. 7x50mm: The 7x means objects appear seven times closer than with the naked eye. The 50mm is the diameter of the front objective lenses in millimeters, which dictates light-gathering power.FULLY COATED: This indicates that all air-to-glass optical surfaces have a special chemical layer to reduce reflections and increase light transmission for a brighter image.355FT / 1000YDS: This is the Field of View (FOV) in standard units. Looking at a distance of 1,000 yards, the width of the visible area is 355 feet wide.119M / 1000M: This is the metric equivalent of the Field of View. At a distance of 1,000 meters, the visible area spans 119 meters wide.  Marine & Boating: The 7x magnification is low enough to keep images stable on a moving boat, while the large 50mm lenses pull in plenty of light over open water.Low-Light Hunting: Excellent for dawn or dusk tracking when animals are most active because the large lenses capture minimal ambient light.Basic Astronomy: The large objective lenses work like small telescopes, making them great for viewing wide-field celestial targets like constellations and the moon
