The ball flight laws are the only absolutes in golf.
How all shots start is according to the club face at impact. Your grip and aim are primarily responsible for the face at impact. How all shots curve is the swing path in relation to the face. Your aim and posture are primarily responsible.
We use the technology to convince the golfer of the face and path as well as the angle of attack and of course speed.
On a practice tee or course, having a device to measure mainly carry distance can be very helpful.
The ball flight doesn’t lie and neither do the numbers.
