GCQuad Launch Monitor
The data measured by our launch monitors
Our launch monitors use a combination of infrared object-tracking and high-speed, high-resolution camera-based technology to precisely measure every aspect of club head and ball launch performance.
By capturing thousands of images per second, building a virtual 3D model, and then analysing a multitude of data components, our technology is able to create the most accurate and complete picture of your ball and club head performance – and deliver the results in real-time.
Camera vs radar launch monitor technology
Our launch monitors use exact photometric measurements taken with a clear, direct view of the impact window.
Our launch monitors 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
The following terms are used to describe various types of ball data, also known as the launch conditions.
Ball speed
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
The total number of revolutions of the golf ball, about the spin-axis, measured in RPM (revolutions per minute).
Golf club data
The following points describe the ball’s journey from the point of contact with the club, to the point that it reaches the ground.
Club speed
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 Attach
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 in degrees of the club head’s face plane position vertically relative to the ground plane.
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.
