The Carson Optical Mini Aura Night Vision Monocular is a compact night vision monocular with the ability to see up to 82 ft. in total darkness! Unlike the murky green images from devices with intensifier tubes that burn out over time, this night vision monocular produces a crisp black and white image with an intensity that can be easily adjusted with the simple push of a button. The monocular can be used in ambient light or total darkness, making it ideal for late night wildlife viewing or hunting at dusk. Backed by a 1 year limited warranty. Requires 3 AAA batteries.
