It’s both a training device and a conventional putter.
Used as a training device you position the putter face 1” behind a golf ball at address so that the shaft is aligned with the back edge of the ball. Making a stroke from this position you will automatically execute the three fundamentals of a perfect stroke.
Shorter Takeaway: Because the head is already 1” behind the ball the takeaway is shorter which minimizes rerouting of the club off of the intended swing plane.
Square Thru Impact: On the forward stroke the golfer is aware that the putter head is back away from the shaft. This requires the golfer to maintain a square putter face for an extra 1” past the normal point of impact.
Longer Follow-Through: The delayed impact requires the golfer to make a longer follow thru, a key to proper putting technique.
Used as a conventional putter the golfer places the head immediately behind the ball. In doing so the golfer must preset the right wrist. This greatly reduces the activity of the hands promoting a more simple and dependable rocking of the shoulders. With the entire head positioned away from the shaft the TourStroke has an extremely high (effective) moment of inertia (MOI) of 20,000 that in turn greatly enhances stability and accuracy. This vast difference in stability combined with a forward preset wrist greatly improves a golfer’s accuracy, especially on shorter high-pressure putts.
