Designed and ready for the great outdoors, these Minox BL HD 10x44 Binoculars feature phase-corrected prisms, high density (HD) glass, anti-reflective multi-coated optics and APD lens elements, which all-in-all leads to remarkably clear and enjoyable viewing - under any light. The 44mm objective lenses increase the light gathering abilities, as well as increasing the angle of view, so you are sure to easily survey the whole scene as you look around.
