The ND5 Long Distance Laser Illuminator is the first high-powered, hand held laser light built for civilian use. The patented design integrates a state of the art micro Green Laser Pump with a hand controlled Linear Optical Collimator to create the ultimate lighting instrument. One hand, thumb control quickly adjusts laser beam diameter and illumination intensity. The high power laser beam may be collimated down and concentrated to cast an intense, highly visible beam of light able to be seen at distances up to 5 miles for signaling or search and rescue operations. Adjusting the ND5’s collimator more open increases the diameter of the beam to fully illuminate objects up to 400 yards or even a trail for night hiking. Excellent source of illumination for hunting, camping or hiking. The ND5 Laser Locator light utilizes a proprietary 20MW Green Laser which operates at 532NM using two, 3V lithium batteries. Green is the easiest light or color for the human eye to see and causes no typical “night blindness” associated with standard or high intensity flashlights. Thus the ND5 provides illumination completely suitable for night work with the least amount of eye adjustment. Allows for full night vision up to 250 yards. Includes cleaning kit, 2 CR 123A Lithium batteries and a padded case. 9 3/4" L x 2 1/4" DIA x 1 1/5" DIA Tube
