For sporting events, in the theatre or in the great outdoors, the Monos are the masters of versatility, fitting snugly in a jacket pocket or handbag. Depending on the model, they are ideal for use as magnifying glasses or even for binocular amplification. They can turn your binoculars into a spotting scope by tripling the magnification. Even the smallest details can be seen: nothing escapes their notice.
