The Yes! Golf Groove Tube features a radical new design that combines form and function. The Yes Groove Tube incorporates 3D visual alignment technology to guarantee perfect address and setup over every putt. By looking through the alignment window and using the centre line at the bottom of the tube, you will see one seamless three-dimensional alignment line that indicates the sightline is correctly positioned over the putter. The Groove Tube's deep weight distribution and near equator centre of gravity work together to reduce twisting on off centre hits and create more immediate roll off the Yes! C-Grooves. The C-Grooves on Yes! Putters are specifically engineered to enhance and maximise the over- rolling motion of the ball. The C-Groove putters roll the ball sooner and truer resulting in more control, accuracy and consistency.
