Get instant feedback on, a variety of shot-types, with the Pill Full-Range Training Aid. Fine tune all elements of your golf game from full swing to putts. The specially engineered shape provides visible feedback when you don't hit a square shot. Inaccurate hits make the ball wobble, roll off-center or fall on its side. A soft, durable Surlyn cover provides a crisp feel at impact and the performance core help replicate the roll of a real golf ball.
