Ever make a beautiful 10-foot putt on a level green only to notice the ball curve away from the hole at the last second? If you thought there must be something wrong with your equipment-you were more correct than you knew. Believe it or not, a perfectly round golf ball has never been manufactured.

Just like automobile tires appear to be perfectly round-yet they still need to be spin balanced before being driven at high speeds. The same holds true for golf balls. The inherent lopsidedness of every ball works against you off the tee and on the green.

The Check-GO™ automatically realigns the balls heaviest areas along its equator, so that the ball no longer has a tendency to wobble, but rather roll more accurately on the green and drive further of the tee with fewer hooks and slices.

GO generates Fxi which is the force that spins the ball in the direction of the arrow.	Upon impact the ball shoots forward with a velocity of about 50-100 MPH. At the same time the loft angle of the clubhead causes the ball to spin at about 2,000-10,000 RPM.	The effect of the back spin imparted generates two newtons of lifting power (five times the power of gravity). This is called the Bernoulli principal. It is the lifting principal which determines the flying distance of the ball.
