Leica Ultravid HD-Plus 7x42mm Roof Prism Binoculars Rubber Armored Black. Leica Ultravid 42 HD-Plus binoculars are available with a magnification factor of 7x 8x or 10x. The 7x magnification is a true leading light and so is ideal for use in the hours approaching darkness. In addition the 7x magnification offers a steady image because hand trembling or engine vibrations e.g. on a boat are not transmitted.
