I have mine out and walk to it once a week all since march to check it. It has a flash and I have some great photo's of the same buck from the whole summer, I am working on putting them on one page so you can see his growth through the year. He comes in about once every 3 - 5 days since I set it up and tonight I got a photo of one I have not seen all year, He has only one horn on his right side and he has come through 3 days in a row with a flash.
