The 7-15x35 Level Zoom Binoculars from Barska integrate a versatile thumb lever that allows you to take in a large field of view at a low magnification, and with a quick slide of the lever, increase the magnification to make detailed observations at a distance. Utilizing a traditional Porro prism optical path provides you with a rich depth of field, and the binoculars' fully multi-coated optics ensure images are bright and clear with enhanced contrast and true color rendition. Their protective rubber armoring is textured to provide a slip-resistant grip, and if you're planning on glassing for extended periods the Level Zoom can be mounted on a tripod using an optional adapter.
