I bought the 250 kill light for my rifle. But now I need a scan light. Do you scan mostly with red lens or white. whats the distance and brightness with a scan light. I know it has to be fairly light tried scanning with the rifle and bipod lastnight arm got tried. lol. I called one in but i had the light off could see with just the moon light. When i turned the light on to shoot him he left the country. Chalk one to a learning curve. so I know with a light I could have seen him sooner.
