These GTHUNDER digital night vision binoculars use an infrared illuminator to show animals and other objects in total darkness, and record photos and video (without sound) to the included 32GB memory card. A 3 inch TFT screen shows the image, the 4x digital zoom reaches targets up to 986 feet away, and the 24mm objective lens is fully multi-coated. A case, neck strap, data cable, manual and cleaning cloth are included.
