Explore the outdoors at night using the compact and water-resistant Nightfall 3.5x42 Digital Night Vision Monocular. With a built-in infrared illuminator and a digital CCD sensor, you obtain detailed images during both day or night, improved range, and adequate visibility in complete darkness. Compared to NVDs with intensifying tubes, the digital night vision sensor has nearly unlimited lifetime and unparalleled resistance to bright light. You don't have to worry about accidentally exposing it to daylight and burning it. The 3.5x objective lens offers a tradeoff between notable magnification, a 5º field of view, and a wider than average 42mm aperture for gathering infrared light. In addition to direct viewing capability, this night vision monocular features an output port for recording night scene videos with an external recording device.
