I decided to use one of my old decoys... It has a small rabbit and a animal with a coon tail.. I used the decoy with the tail . I called two fox in one from each direction to the decoy and when they saw it they ran away....This decoy device also illuminated the decoy for night use. SO I know the fox actually saw it as they crested a hill and came out the side of still standing corn field. The breaks went on and they turned and hauled it!!!
