Putter Face Aim Calibration (Alignment Rods & String Line)
Calibrate alignment and eye position using parallel alignment rods and an overhead string line.
Key points
- Set two parallel rods forming a start channel to square the putter alignment mark
- Use an overhead string line split down the center of the ball to check distance from the ball and neck tilt
- Match the putter face line precisely parallel with the target track before stroking
Common mistakes
Manipulating eye line or tilting the neck inconsistently, causing the golfer to aim off-target without realizing it.
