It can be real good for you or it can be real bad. Sub-dominant birds will shy away from it and stay out of range. So do be aware of that. I like to place mine close and make it look as natural as possible. I have been experimentin g with strutting toms long before these came out. They can work beyond your belief. You all seen the videos. Or it will make a good Tom stay away as I have had it both ways. I have played with both a real tom fan and a jake fan. The jake fan worked this time somewhat. I do beleive it worked more as I pulled all his hens away from him. And this Tom was reported to me as the Tom who runs off other Toms - but he sure took his time getting to me.
