These are the field binoculars that attach to an iPhone for easy viewing and recording. The view through the eyepiece transfers to the phone’s camera lens, turning the phone into a viewfinder for sharing the sights with friends or taking pictures of the action. The 36mm lenses on the binoculars deliver 8X magnification for a 465-foot field of view at 1,000 yards. When the phone is in camera mode, the screen displays all magnified images as if it were an external monitor. The included phone case seals snugly over one eyepiece, aligning the phone’s camera with the binocular lens. Included phone cases fit iPhone 5/5S and 4/4S. The field glasses also function as standard binoculars when detached. Includes carrying case and cleaning cloth. 1 3/4" H x 6" W x 7" L. (2 lbs.)
