Easily stored in a pocket or purse, Zeiss Monoculars can be used as magnifying glasses or for transforming your binoculars into a spotting scope by tripling the magnification. These monoculars offer a tiny splash-proof housing, large field of view, Zeiss T* multi-layer coating for high light transmission, close focus capabilities, and a diopter adjustment +/- 4 diopters. Ideal for sporting events, reading, concerts, or the great outdoors, monos are the masters of versatility.
