Club Head Data describes the measured delivery of the club head at impact. This data includes measurements of club head motion, face orientation, and impact location.
Club head delivery is described by:
Path
Face plane
Velocity
Impact location
Foresight Sports HMT Head Measurement Technology uses high-speed, high-resolution cameras to capture club head information with a high degree of accuracy.
Introduction to Club Head Measurement
Head Measurement is the measurement of the delivery of the club head described by:
Path
Face plane
Velocity
Impact location of the golf ball
The following sections describe each measured club head parameter.
Club Head Measurement Metrics
Club Speed
The velocity that the club head travels measured just prior to ball contact.
Efficiency
The ratio between club head and golf ball velocities to determine the quality of the ball strike.
Described as:
Ball Speed ÷ Club Speed = Efficiency (Smash Factor)
Angle of Attack
The descending or ascending path of the club head measured in degrees.
Club Path
The swing path measured in a horizontal plane relative to the target line.
Face to Target
The face angle relative to the target line at impact.
Face to Path
The face angle relative to the club path. The main components in generating side angle and the curvature of the golf ball.
Lie
The dynamic measurement in degrees of the club head’s face plane position horizontally relative to the ground plane. Also known as roll.
Face Angle
The dynamic measurement, in degrees, of the club head’s face plane position at a right angle (90 degrees) perpendicular relative to the target line or swing path. Also known as yaw.
Impact Location
The measurement, in millimeters, of the contact point of the golf ball on the club face relative to face center.
Closure Rate
The rotation of the club head heel to toe measured about the shaft in degrees per second or RPM.
Loft
The dynamic measurement in degrees of the club head’s face plane position vertically relative to the ground plane. Also known as pitch.
F-Axis
The perpendicular axis measured relative to the directional path that the golf ball rolls or slides up the club face.
In a typical shot where ball impact is centered on the club, the F-Axis and Spin-Tilt Axis should coincide.
Relationship Between Club Delivery & Ball Flight
Club head delivery measurements directly influence ball launch measurements. Club Speed, face orientation, and impact location affect:
Ball Speed
Spin Characteristics
Launch Direction
Shot Curvature
Ball flight outcomes are determined by the interaction of club delivery and ball launch conditions.
