Compact binoculars are by far the most popular type of binocular; they are ideal for walking, sporting events, theatre and opera. The generally small size means they can be placed in a bag or even the pocket. The Swarovski 8x20 boasts no fewer than 16 lenses and yields an unexpectedly wide field of view and brilliant, contrast-rich images with a weight of less than 215 g (8 oz.). This model is one of the few compacts which are nitrogen filled and fully waterproof.
