What, how, and when we track.

Full Swing

Club Speed

The linear speed of the club head’s geometric center just prior to first contact with the golf ball.

Attack Angle

The up or down movement of the club head’s geometric center at the time of maximum compression.

Dynamic Loft

The vertical angle of the club face at the center-point of contact between the club and ball at the time of maximum compression.

Club path

The in-to-out or out-to-in movement of the club head’s geometric center at the time of maximum compression.

Face Angle

The direction the club face is pointing at the center-point of contact between the club and ball at the time of maximum compression.

Face to Path

The angle difference between the reported face angle and club path.

Spin Loft

The angle between the direction of the club head’s movement and the club face’s orientation at the time of maximum compression.

Swing Plane

The vertical angle between the plane created by the club head’s geometric center movement and the horizon.

Swing Direction

The angle between the base of the plane created by the club head’s geometric center movement and the target line.

Low Point

Distance from the club head’s geometric center to the lowest point on the swing arc at the time of maximum compression.

Impact Height

The vertical impact location distance relative to the center of the face.

Impact Offset

The horizontal impact location distance relative to the center of the face.

Dynamic Lie

The angle of the lower portion of the shaft relative to the waterline at impact.

Ball Speed

The speed of the golf ball’s center of gravity immediately after separation from the club face.

Smash Factor

The ratio between the measured ball speed and measured club speed.

Launch Angle

The vertical angle the golf ball takes off at relative to the horizon and measured immediately after separation from the club face.

Spin Rate

The rate of rotation of the golf ball about the imaginary line the golf ball rotates around measured immediately after separation from the club face.

Launch Direction

The horizontal angle the golf ball takes off at relative to the target line and measured immediately after separation from the club face.

Spin Axis

The angle relative to the horizon of the imaginary line that the golf ball rotates around and is measured after separation from the club face.

Height

The maximum height or apex of the trajectory measured relative to the elevation at which the golf ball was launched.

Curve

The horizontal side movement perpendicular from the launch direction to carry side.

Landing Angle

The angle the golf ball lands at relative to the horizon and at a point that has the same elevation as where it was launched.

Carry

The straight-line distance between where the golf ball was launched from and where it crosses a point that has the same elevation.

Side

The perpendicular distance between the target line and where the trajectory crosses a point that has the same elevation as where the golf ball was launched.

Total

The straight-line distance between where the golf ball was launched from and its calculated resting position.

Side Total

The perpendicular distance between the target line and the golf ball’s calculated resting position.
