CARRY DISTANCE

The amount of distance the ball travels through the air.

BALL SPEED

The measurement of the golf ball’s velocity just after impact. Ball speed is the main component in generating distance.

TOTAL SPIN

The amount of total spin created around the tilt axis is expressed as total spin. This will determine the curve and lift of the shot.

VERTICAL LAUNCH ANGLE

Commonly referred to as "launch angle" for short, this metric is the initial vertical angle of ascent relative to the ground plane measured in degrees. The launch angle, combined with ball spin and speed, will determine the ball's carry and total distance.

HORIZONTAL LAUNCH ANGLE

Also know as "Azimuth," side angle, or deviation angle, it's the initial horizontal angel relative to the target line. Horizontal launch angle, combined with side spin, will determine the final ball position range relative to the target line.

SPIN TILT AXIS*

One of the most important pieces of data measure is spin-tilt axis. The spin-tilt axis is the axis that the golf ball rotates around to create shot curvature and lift.

BACK SPIN*

A component of total spin that defines ball lift and trajectory.

SIDE SPIN*

A component of total spin that defines ball curvature or shot shape; related to the spin-tilt axis.

CLUB HEAD SPEED

The velocity at which the head travels, measured just prior to ball contact.

SMASH FACTOR

Smash Factor, also know as Efficiency, is the ratio between club head and golf ball velocities.

CLUB PATH*

The swing path measured in a horizontal plane relative to the target line. This data point will tell you if the club was moving from inside-out, outside-in, or perfectly down the line.

ANGLE OF ATTACK*

The descending or ascending path of the club head, measured in degrees. A positive number is hitting up on the ball and a negative number is hitting down on the ball.
