Ball Roll / Spin

The average rotation of the golf ball during the first 6 frames after Impact. It enables you to measure the amount of Spin (Backspin or Overspin) imparted on the golf ball.

Start of Forward Rotation:
Does the golf ball has positive RPM rotation or negative rotation at the point of impact. In certain instances during impact, the golf ball is imparted with backspin and hence has a negative rotation. In this instance the ‘Start of Forward Rotation’ is the point the ball stops spinning backwards and starts to rotate forwards due to the friction with the surface.

Cut (+) / Hook (-) Spin:
Are you putting cut or hook spin on your putts. If the side spin is between 10–20 rpm (either cut or hook) the number will turn Orange, anything over 20 rpm it will turn Red, under 10 rpm it will be Green. Anything under 20 rpm either cut or hook is an acceptable degree of spin and will not have a significant effect on the path of the ball. Once the RPM starts to go above 20 rpm you may need to change the fitting of the putter: for example lie angle, face balanced vs. toe heavy to correct the spin rate without changing the technique of the golfer. However, if you have a SPIN rate over 60 rpm, you may need to also fix/address their putting stroke…. Greater than 20 rpm of Cut or Hook spin is enough side spin to cause the golf ball to change its intended path (i.e. miss the hole) when putting over a distance of 10ft

In some cases, players like to have a forward lean on their putter shaft, Phil Mickelson for example. With a 6.00 degree shaft lean at impact, he requires a combination of positive attack angle and static loft of the putter to create a positive launch angle (1 degree) of the golf ball... It is also possible to create a positive 1 degree launch angle of the golf ball with a negative shaft angle (leaning backwards at impact). What would be the static loft of the putter in this instance? Remember, we don't want a negative attack angle, as this will trap the golf ball into the ground, create large over spin values and potential bounce even higher after being driven into the ground.

* Trapping the ball in the surface will also cause the ball to have increased side-spin values
