* Clearly See in 100% Darkness - While other night vision spy gear can't provide high-quality photos & videos without ambient light, drain your batteries within minutes or they are impossible to focus and zoom, the IR High-Tech Night Vision Binoculars feature an 850 NM infrared illuminator which allows you to view animals in pitch dark for hours. The focus is smooth making it simple to capture crisp photos & videos. Use the 4" viewing screen.
