DESCRIPTION

If you hit a ball off the toe of an ordinary iron, it will start off to the right, as the impact "opens" the club face. But then a stronger force, called the gear effect, takes over and spins the ball violently to the left. The reverse happens with a heel shot. It "closes" the club face and starts off to the left, then the gear effect slices it wildly to the right. The Controller driving irons have a patented "invisible" curve (you can feel it, but barely see it) across their hitting surface that tames the stronger gear effect and draws off-centre shots back to the middle of the fairway. It''s a major golfing breakthrough and, along with their massive power, probably makes the Controllers the longest and straightest clubs in golf today.
