I always have it in my jacket pocket. I have used in on 1/2 of the deer I have gotten with a bow. The rest were so close it didnt matter much. I typically use it when the deer is walking or feeding in an area that I am not 100% sure of the yardage since I range everything that is around me but sometimes I just forget how far things are. They are a great tool if you have the time to use it.
