# WHAT CAN TRACKMAN TRACK?

**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.

**Putting**

**Club Speed**

The speed the club head is traveling immediately prior to impact.

**Backswing Time**

The time the club head is traveling away from the ball.

**Stroke Length**

The distance the club head is pulled back from the ball in the backswing.

**Forward Swing Time**

The time the club head is traveling towards the ball until impact.

**Tempo**

The Backswing time divided by the Forward swing time.

**Dynamic Lie**

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

**Launch Direction**

The angle the ball starts right or left in relation to the target line.

**Ball Speed**

Initial ball speed immediately after separation from the putter face.

**Skid Distance**

The distance the ball is bouncing/sliding until it starts to roll.

**Roll Speed**

Speed at the point where the ball starts to roll.

**Speed Drop**

The percentage drop in speed from Ball Speed to Roll Speed.

**Roll %**

The amount of roll on the total putt distance.

**Effective Stim**

The speed of the individual putt, based on the average roll deceleration.

**Side**

The total side distance from the target at the time the ball reaches entry speed.

**Break**

The total side movement from the ball’s launch direction, at the time the ball reaches entry speed.

**Distance**

The total distance in a straight line from the starting point.

**Attack Angle**

The up or down movement of the club head’s geometric center at the time of impact

**Club Path**

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

**Face Angle**

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

**Face to Path**

The angle difference between the reported face angle and club path

**Entry Speed Distance**

The straight-line distance between where the golf ball was launched from and the point of entry speed (1.68 mph)

**Elevation**

The height difference from the ball’s starting position to the point of entry speed

**Slope %**

The average horizontal inclination of the surface

**Slope % rise**

The average vertical inclination of the surface

**Stimp (flat)**

The calculation of green’s general speed, based on the average roll deceleration of the individual putt
