The Effect of COR in Your Shot


COR, which is short for Coefficient of Restitution is technically the measurement of the energy transfer between the collisions of two objects. It can be expressed as a number between 0 and 1. Knowledgeable golfers define COR as a value that represents how far a shot can go using a particular clubhead given a certain swing speed.

The term COR entered and became accepted in the golf industry language when the USGA clamored about the increased distances golf professionals made way back in 1998. Blaming the newly released titanium drivers at that time, the USGA came up with a rule placing a limited value of COR of all driver faces. The decision was made without any hesitation or further research.

Then if USGA places 0.83 as the COR limit of driver faces, it means that the energy transfer between the driver head and the golf ball must not be more than 83%. Otherwise, the driver will not conform to the standard rules of golf set by the association.

But the thing is, there is always a loss of energy during a collision between the clubhead and the ball since the clubhead face flexes inward while the ball is compressed towards the face. Scientists believe that 80% of the lost energy comes from the ball while the other 20% comes is resulted by the clubhead. The higher COR, therefore, means that the clubhead is designed to allow more inward flexing to prevent the ball from compressing too much towards the club face. So clubheads with higher COR tends to go farther distance regardless of the clubhead speed.

TrackMan Pro is Changing the Golf Swing


TrackMan Pro is the newest innovation in the world of golf. It is practically a Doppler radar system designed to analyze, evaluate and change the way golfers swing their clubs. Both professionals and rookies can benefit from this technology. Sean Foley and Tiger Woods, two big names in the golf world, are using it. Young kids learning golf are taking advantage of this equipment. Top golf clubs already have it in use.

Savoie, who has been a golf coach and instructor at Arkansas and Florida State, said that the TrackMan Pro changed the way he does his job. He said that he used to be frustrated realizing that different instructors can have differing opinions of the same swing. He noted that there is a lot of subjectivity when teaching golf, which can lead to confusion and disagreement over a player’s technique.

With the aid of the TrackMan Pro, golf instruction has become scientific and precise. Computer-generated data explains why a golfer doesn’t accomplish the shot he intended to make. The club speed, ball speed, attack angle and spin rate are few of the factors computed by the device. Given such data, both the golfer and coach are able to better understand what happened during that particular shot. Then adjustments can be made to achieve the best game possible.
