With so many different data parameter which Trackman is able to measure it can be difficult to remember all of them. Please see below definitions for all Trackman data parameters for both Full Swing & Putting data.
Trackman Data Parameters
Club Speed
The linear speed of the club head's geometric center just prior to first touch 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.
Swing Radius
Radius of the swing arc – measured at knee height until just before impact, i.e. the club trajectory from 8pm until impact and then fitting a circle to it and measuring the radius. Swing Radius can be used as a measure, when trying to maximize power generation in the swing or to optimize the club trajectory for pitch and chip shots.
Max Height - Distance
The distance at which the ball reaches its maximum height - Slightly different than the apex which represents only the maximum height
Low Point Height
The relative vertical distance of the club head position at the time of maximum compression to where the swing would bottom out if there was no interaction between the ball or the ground
Low Point Side
The relative horizontal distance of the club head measured perpendicular to the target line of the club head position at the time of maximum compression to where the swing would bottom out if there was no interaction between the ball or the ground
D Plane Tilt
It is the tilt of the D Plane relative to the plumb line. If face-to-path is zero, D plane tilt will be zero.D plane tilt is the expected Spin Axis discarding any gear effect because of off-center strike or other factors like ground contact of the club head during the collision with the ball, abnormal friction conditions etc.
Trackman Putting Data Parameters
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
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
Club Path
The in-to-out or out-to-in movement of the club head's geometric center at the time of impact
Face To Path
The angle difference between the reported face angle and club path
Attack Angle
The up or down movement of the club head's geometric center at the time of impact
Launch Direction
The angle the ball starts right or left in relation to the target line
Launch Angle
The vertical angle the golf ball takes off at relative to the horizon and measured immediately after separation from the club face
Bounces
The number of bounces on the ground during the skid phase
Skid Type - Sliding displayed at Launch Angle
Ball with constant deceleration during skid phase (no bounces, sliding on the ground)
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
Entry Speed Distance
The straight-line distance between where the golf ball was launched from and the point of entry speed (1.68 mph)
Side
The total side distance from the target at the time the ball reaches entry speed
Distance
The total distance in a straight line from the starting point
Effective Stimp
The speed of the individual putt, based on the average roll deceleration
Flat Stimp
The calculation of green's general speed, based on the average roll deceleration of the individual putt
Elevation
The height difference from the ball's starting position to the point of entry speed
Break
The total side movement from the ball’s launch direction, at the time the ball reaches entry speed
