    Easy to use

    One of the great features of the 8x21 binoculars is how easy they are to use. Both barrels can be adjusted to suit your eyes, while the central focus wheel moves smoothly but precisely to produce a crystal-clear view. The diopter adjuster on the right eyepiece can also be used to make fine adjustments. No previous binocular experience is required, making it possible for adults and children of all ages to explore the world around them.
