Small in size, big in performance. These mini binoculars provide a very sharp and detailed image and can be focussed from 1.8 meter. Because of the nitrogen gas filling these binoculars are waterproof. They are also suitable for people who wear glasses and for people who don't because of the nice twist-up ocular. The prisms are phase coated and equipped with high reflection aluminium coating which ensures a sharp image with true-to-life colours.
