Combined with any night vision riflescope or monocular, the Sightmark Infrared Illuminator acts as a flashlight during night vision use. With the Infrared Illuminator, the user can illuminate the target without the prey detecting it. It is great for indoor and outdoor use, where there is low ambient light, such as during a SWAT raid in a dark warehouse or varmint hunting out on a moonless night. Operable with two AAA batteries, it offers two power options, a low output at 70 milliwatts and a high output at 100 milliwatts for a more powerful and brighter experience. Featuring a battery life of 20 hours, the Infrared Illuminator also has an adjustable beam focus to widen or narrow the stream of light. As long as the enemy does not have night vision, the IR flashlight can be used for covert signaling at night. The Infrared Illuminator comes with a standard one-inch weaver mount that fits most AR15s and average rifles and a nylon carrying case for easy storage.
