last year was the first time i used it, i used 1 time on a 6 point. i let him walk by but at about 20 yds past me i would hit the can and he would walk back right under my tree, i did it 3 times just messing with himand he came back each time...heres the funny part i attempted a 4th try and turnedthe can overhalf a** and made a terrible sound!! he didnt like that and left!! quite funny...30 mins later i shot my biggest buck. BUT yea it works!!!
