These laser pointers produce an intense beam that is highly visible under most conditions. In darkness and even low-light, the entire beam is visible as it cuts through the air, making it an excellent long-range pointing device (as an astronomical aid to point out stars and planets, for example). Intensity is about 35 times brighter than a red 670 nm basic laser pen. Visible effects are greatly enhanced over water, in the fog, rain or snow and humidty, and at night. If one was to look in the direction of the laser, it would appear as the brightest source of light on the horizon from a distance of many miles.
