Club Speed:
Club speed measured just before impact. Club speed varies a lot between the different tour players. Tiger Woods is among the players with the highest driver club speed - averaging around 124 mph. The Tour Pro Average is 113 mph for a Driver and 95 mph for a 5 iron.

Vertical Swing Plane:
The angle of the swing plane of the club head seen from ground and up. A high value is a steep swing plane - Low value is a flat swing plane. The primary goal is to have a consistent vertical swing plane. Tour Pro Average with the Driver is 48 degrees

Horizontal Swing Plane:
The swing plane of the club head - seen from above. Orientation left/ right measured in relation to the target Line. Positive value means swing plane orientation toward the right (inside/out for right handed player) and a negative value means orientation towards the left (outside/in).

Attack Angle:
The angle with which the club head is "attacking" the ball just before impact - measured in relation to ground level. Negative value is hitting down on the ball, and positive is hitting up on the ball. This is a very important number for club fitters.

Dynamic Loft:
The dynamic or effective loft of the club at the point of impact on the club face - calculated relative to vertical. When hitting down on the ball, the dynamic loft will normally be less than the static loft of the club.

Club Path:
The club head path measured at impact. Positive value if club head is moving to the right (inside/out for right handed player) and negative value is a club head moving to the left through impact. A shot with a Club Path value between -1 to +1 degree is considered to be straight towards the target.

Face Angle:
The club head angle calculated at impact on the club face relative to the target line. A positive value if the the Club head is open at impact.

Ball Speed:
Ball speed measured just after impact. A high ball speed is primarily generated from a high club speed. However, the impact location on the club, the dynamic loft, and the attack angle also play a role in producing the ball speed.

Spin Rate:
The launch spin measured just after impact. Spin is of major importance for the carry distance and launch angle for high speed shots - a drive in particular. To maximize the driving distance a combination of high launch angle and low spin is needed.

Smash Factor:
Ball speed divided by Club speed. It represents the ability to transfer power from the club to the ball. 1.48 is maximum for a driver (COR regulated)

Spin Axis:
The spin axis is the axis around which the ball is spinning. The tilting of the axis dictates if the ball will draw or fade. The value is +/- in degrees relative to the horizon. Positive value when the ball is going right - and negative when it's going left.

Vertical Launch Angle:
The launch angle measuered just after impact in relation to the horizon. The optimal launch angle for a driver is individual for each player and is primarily dictated by club speed and attack angle. The TrackMan driver fitting application takes the mystery out of finding the optimal launch angle for each palyer.

Horizontal Launch Angle:
The launch angle measured just after impact in relation to target line.

Maximum Height:
The measured maximum height of the ball during the ball flight. The height of golf shots are more or less the same for every club in the bag.

Landing Angle:
The measured landing angle in relation to the horizon. Keep it below 40 degrees for a driver. Get it higher than 55 degrees for control on approach shots. Tour Pro average - Driver 39 degrees.

Carry:
The carry - measured to same level as launch (carry flat). Tour Pro Average - Driver: 262 yds

Carry Side:
The carry side - measured in relation to target line

Total distance:
equals carry plus calculated bounce and roll.

Total Side:
The total side (left or right) calculated in relation to target line.
