I have used horses for decoys.They work very very good. As for the cow elkIII I have not seen them work real good so far.Most the elk I call in are looking and listening for movment not just a elk. I think movement is way better than a good pic of an elk.Tie the horse bake in the woods far enough the elk can not see it unless it walks right by you.Some times just the chewing is enough to get a bull to come to you.You may not even need to call :}
