With distance becoming a bigger and bigger topic in the world of professional golf, an acronym that has risen alongside that is CT which means 'characteristic time'.
What is a good CT for a driver?
Per the USGA and R&A rules, drivers cannot exceed a CT (characteristic time) reading of 257 – the limit is 239, but there's a tolerance of 18 -- or they are deemed illegal.
What do the letters on golf clubs mean?
Again, breaking it down to its simplest form, the numbers on your golf clubs relate to how far they hit the ball - the lower the number, the further the ball should travel. A club with a #4 on it will hit the ball further than one with a #9 on it.
What is coefficient of restitution in golf?
The coefficient of restitution is basically a term that describes energy transferred between two objects. The COR figure for Object A is a measurement of Object A's ability to transfer energy to Object B when the two collide. So in terms of golf, A is the golf club and B is the golf ball.
What is Cor in golf drivers?
What is COR in golf clubs? COR stands for Coefficient of Restitution. This is defined as the ratio of the final velocity to the initial velocity between two objects after their collision. Basically COR is a measurement of the energy loss or retention when two objects collide.
45 related questions foundWhat is an illegal driver in golf?
First, what is an illegal golf driver? Any golf driver that doesn't conform to USGA and R&A rules is considered illegal. The most common type of illegal golf drivers offer a high COR. A COR value above 0.83 (legal max) will offer more distance for most golfers that use it.
What is a high COR driver?
HIGH (COR) COEFFICIENT OF RESTITUTION DESIGN
COR is the measurement of how a ball, slingshots off the face of a driver.
Would a golfer benefit more from a driver with a higher or lower COR?
Here's how COR matters in a golf club: If, say, a fairway wood or iron has a very high COR, then there is less energy loss at impact with the golf ball compared to a fairway wood or iron with a lower COR. All other things being equal, a higher COR measurement in a golf club equates to more distance.
What should my smash factor be?
Smash Factor is ball speed divided by club speed
A golfer would hope to achieve a smash factor near 1.50 on driver shots. That means for a 100 mph club speed the ball speed would be 150 mph. The higher the loft of the club, the lower the smash factor is expected to be. A PW should have a smash factor near 1.25.
What is Cor golf?
COR is one of a few acronyms that golf equipment manufacturers use when describing their latest products - but what does it actually mean? First, the 'science-y' stuff. COR stands for coefficient of restitution and is the ratio of the final to initial relative velocity between two objects after they collide.
What does HC mean on a golf club?
A course handicap is the number of strokes a player receives on a particular course. Course handicap = Handicap Index X Slope Rating/113 + (Course Rating-Par) Example: This course handicap calculation assumes a 12.7 and a course slope of 115.
What does the G mean on a golf club?
A “GW” is an important club known as the gap wedge. As the name implies, it fills in the large distance gap found between your pitching wedge (PW) and sand wedge (SW), which occurs because of the large difference in the lofts of those two clubs.
How is cor measured?
COR is measured by launching a ball at the face of the golf club and measuring the speed velocity of the ball before and after it has made contact with the clubface.
How fast should you swing a 7 iron?
An average golfer will swing a seven iron about 75 mph. This number can change based on the weight of the club and if it is steel or graphite. The faster you swing a seven iron, the further it will go. If you can swing at about 85 mph, you will see distances closer to 165 yards.
What is the swing speed of an average golfer?

Do illegal golf balls work?

What makes a golf ball Illegal?
The longest illegal golf balls on the market are the 2 piece Bandit golf balls. The USGA had to make these illegal because they have a very aerodynamic dimple design that helps the ball travel a long way. They have low spin off the tee and will dramatically increase the length of your drives.
Does golf club shaving work?
The data suggest that the shaved face driver does exactly what it is intended to do: Shaving the face of a driver produces ball speeds on average of 4 mph faster than a stock head. Higher ball speeds equal longer distances; the shaved Jetspeed traveled a full 10 yards farther than its USGA-conforming counterpart.
