The Yes Golf Hanna is a centre shafted mallet putter. Yes Hanna is a face balanced, centre shafted mallet head style, made of 304 stainless steel with a head weight of 355 grams. The toe-heel weight distribution across the face is designed to stabilize the head and provide maximum forgiveness. The Yes Hanna features a long single sight line for effortless alignment with the target. YES Hanna has the C-Groove putter face technology that is manufactured with a precision-milled set of concentric, C-shaped grooves. These grooves are specifically engineered to enhance and maximize the over-rolling motion of the ball. C-Groove putters roll the ball sooner and truer resulting in more control, accuracy and consistency.
