Every stroke is influenced by weight, balance, and center of gravity.
The Modulator is designed to give you control over all three.
By fine-tuning how mass is distributed, it subtly changes how the putter moves, feels, and delivers at impact—helping you find your most consistent roll.
"Excellent inherent balance and pleasing feel. The light overall mass requires slightly more deliberate effort on the downstroke to reach the hole. Sweet-spot and toe strikes produce pure, immediate end-over end roll with excellent directional control. Heel strikes generate an unpleasant sound, reduced feedback, and a tendency to miss left."
-
"Outstanding performance. Extremely smooth and effortless stroke. Sweet-spot contact yields a confident, purposeful roll. Demonstrated exceptional consistency (50 consecutive makes from the center, followed by 15 additional from the toe). Toe misses remain highly playable; heel strikes are the only weak area. Highly recommended."
-
"Very soft feel at impact with a muted sound. Remarkable toe forgiveness — off-center toe strikes often produce gentle right-to left shape while staying on line. Sweet-spot putts exhibit zero skid and pure roll. Ideal for golfers who find the 25 g configuration too light."
-
"Superb face squaring and balance. Extremely easy to align and return to square. High make percentage even when putting one handed. Pure roll with excellent distance control, though the added stability can tempt the player to hit the ball slightly past the hole if not careful."
Useful for start-line control and off-center strike response.
