The Controller® Driving Iron features a patented shot-control system that automatically corrects hooks and slices whilst giving 15% more hitting power than woods and more accuracy that irons. The ‘Roll and Bulge’ design tames the hook-and-slice spins caused by off-centre shots. The Controller out-hits drivers because its head is smaller and 15% heavier than oversized steel and titanium drivers. The smaller head reduces drag, increases club-head speed and concentrates more mass directly behind the ball. No driver can match this concentration of power!
