A device allows a golfer to hit full swing golf shots with a real ball in a limited area while still providing the golfer with trajectory information about their shot and realistic feel of an actual golf ball. The device tethers a golf ball to the ground. When the golfer swings, the ball flies about 20 yards and drops to the ground. The device is easy to use and affordable. The device is made from two different cord materials, one being more elastic than the other, allowing the golfer to hit a ball without having the ball spring back to hit the golfer. The golf ball can be attached to the cord with a lightweight screw eye screwed into the ball.
