Years ago I purchased a video by Bruce Scott about being a better dove shot. In the video they were using an aluminum pole set up and talked about how to place it in the field. Well I purchased one and Stan is right. Doves have flown over the field and done a 180 to come and check it out.
A couple of years ago one December afternoon me and a friend was in a "HOT" dove field. Doves were all over the place. I had just set the pole up and my friend was saying because it was bare shiny aluminum no doves would come to it. At that time I asked him to turn around and two doves were trying to land on the pole with my decoys.
