I am with mojotex. Calls only work on deer if they are not pressured or there are local doe in heat. Doe are only in heat about two days from what I have seen. If you have an area that is reserved for you, they may work. Deer are not stupid. I used calls long ago, but gave them up because they were not worth it. I have actually seen bucks circle around out in the brush to get down wind of whatever was calling. Then they sneak off. I have seen smaller bucks run away. Most older deer have been exposed to calls and will not come running in. Deer adapt quickly. I can remember when the saying "Deer never look up" was true. Not anymore. They get a wiff of human scent, do a quick scan at ground level, and then start looking in the trees. Same with calls. To many people using them. For the amount of times a call works, you would be better off with a little Tink's lure on a rag about 10 feet off the ground.
