None! I' m on the side of the debate on decoys that say they can do more harm than good. Too often, toms will either hang-up or turn the other way and leave. If you' re able to get a copy of this month' s Turkey Call magazine (put out by the NWTF) there is an article on this very subject. The reason many theorize that this happens is because decoys are not lifelike enough, sit on the stakes too high, have no motion, etc. They really don' t know why......I' ll take mine, but probably won' t use them.
