There is plenty of variety in the Swarovski binoculars and one may select from the many models but, one thing is for sure, they are waterproof, nitrogen purged as well as phase corrected. A pair of these binoculars will have fit-and-feel characteristics such as easy-grip rubber shells, the ability to lock the diopter adjustments as well as objective lens caps that are attached to the binoculars and, thus not prone to being lost. Like cameras and cell phones, binoculars are getting smaller and smaller. The advantage of compact binoculars is that they are easy to carry and use. It is also easier for a thief to walk off with a pair of compact binoculars.
