The cow decoy worked! We closed the distance on a group of antelope from 800 yards to 175 yards and took a nice buck antelope. After the shot, the does with the buck were confused. They walked right toward us. We kept stalking to within 22 yards of a doe and a fawn. We did have an unsuccessful stalk with the cow decoy. The sun was to our side and for a split second the angle of the sun hit the decoy. This caused the antelope to bolt. Make sure you get the sun at your back when using the decoy on a stalk. We also had success by working our way through cows toward the antelope. This added to the realness of the situation. This product assembles easily. It comes folded in 3 with a bar that fastens to the corugated plastic on the back. The bar works well as the handhold for 1 or 2 people. There are 2 slits that can be punched out for viewing. We used the decoy with 2 people. For the shot we simply had the walker take 2 extra steps past the shooter to allow the shooter to get set up on a tripod. When ready, we backed up and lowered the cow decoy right under the gun barrel, covered our ears and took the shot -- worked pretty slick. Next year we are going after antelope via bow and plan to try out both the cow decoy and a buck decoy.
