Introduction to Club Head Data

As with the GC2 Smart Camera System, Foresight Sports’ HMT Head Measurement Technology uses high-speed, high-resolution cameras to capture club head information with a high degree of accuracy.

This portion of the reference guide provides a basic description of the club head conditions that are measured by the HMT Head Measurement Technology

Introduction to Head Measurement

Head Measurement is the measurement of the delivery of the club head described by path, face plane, velocity and impact location of the golf ball.

The following pages will briefl describe each of these measured parameters.

CLUB SPEED

The velocity that the club head travels measured just prior to ball contact.

Introduction to Head Measurement

EFFICIENCY

The ratio between club head and golf ball velocities to determine the quality of the ball strike.

Described as ball speed divided by head speed = ratio effiiency or smash factor.

EFFICIENCY

ANGLE OF ATTACK

The descending or ascending path of the club-head measured in degrees.

ANGLE OF ATTACK

CLUB PATH

The swing path measured in a horizontal plane relative to the target-line.

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.

FACE TO TARGET

The face angle relative to the target-line at impact.

FACE TO TARGET

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.

FACE TO PATH

LIE

The dynamic measurement in degrees of the club head’s face plane position horizontally relative to the ground plane. Also known as roll.

LIE

LOFT

The dynamic measurement in degrees of the club head’s face plane position vertically relative to the ground plane. Also known as pitch.

LOFT

CLOSURE RATE

The rotation of the club head heel to toe measured about the shaft in degrees per second or rpm.

CLOSURE RATE

IMPACT LOCATION

The measurement (in millimeters) of the contact point of the golf ball on the club face relative to face center.

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.
