What we measure.

Using infrared tracking and ultra-high-speed, high-resolution cameras, our launch monitors capture thousands of images per second to build a precise 3D model of every shot. The result is the most complete and accurate view of ball and club performance, delivered in real time.

Camera vs radar.

Our launch monitors use exact photometric measurements taken with a clear, direct view of the impact window.

We measure club head data by directly imaging the club face. This provides far more reliable and accurate data than radar-based systems, which are positioned behind the golfer and have no direct view of the club face.

Golf ball data.

Ball speed.

The measurement of the ball speed immediately after impact.

Launch angle.

The vertical start direction of the golf ball, relative to the ground plane, measured in degrees.

Side angle.

The horizontal start direction of the golf ball, relative to the target line, measured in degrees. Often referred to as push / pull. A ball starting right of target is shown as a positive number, a ball starting left is shown as a negative number.

Total spin.

The total number of revolutions of the golf ball, about the spin-axis, measured in RPM (revolutions per minute).

Spin-tilt axis.

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

Golf club data.

Club speed.

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

Efficiency.

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

Impact point.

The precise measurement of the contact point of the golf ball on the club face, relative to the face centre, as determined by the fiducial placement.

Angle of attack.

The vertical direction the golf club is travelling immediately prior to impact, relative to the ground plane, measured in degrees. A positive number is known as ‘hitting up’ on the ball and a negative number is known as ‘hitting down’ on the ball.

Club path.

The horizontal direction the golf club is travelling immediately prior to impact, relative to the target line, measured in degrees. A positive number shows the club was travelling to the right of the target line, a negative number shows the club was travelling to the left of the target line.

Face angle at impact.

The measurement of the club head’s face plane position square to either the path or the target line.

Lie angle at impact.

The angle of the club’s sole immediately prior to impact, relative to the ground plane, measured from the centre toe and heel fiducials, displayed in degrees. A negative number means the club is ‘toe down’ at impact, while a positive number means the club is ‘toe up’.

Loft at impact

The measurement of the club head’s face plane position square to either the path or the target line.

Closure rate.

The three dimensional ‘closing’ of the club face immediately prior to impact, encompassing change in loft, lie and face angle, measured in degrees per second.
