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 does CT mean in golf clubs?
characteristic timeWith 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 degree driver is best for slice?
If you want the best driver for a slice I would suggest you opt for the 11.5-degree set up. This will only launch the ball 1-degree higher than the 10.5 option, but the additional backspin will minimise the effect of any slice-spin during the golf ball's flight.
Will draw setting on driver help slice?
In my experience, an adjustable driver will NOT fix your slice. I had a slice with my driver and nothing changed when I switched to an adjustable with a draw bias. Sure, it can help a little but you'll end up with a very similar result. The only thing that's going to fix your slice is to change your swing.
What makes a golf driver illegal?
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.
What degree driver hits the farthest?
The low loft of a golf driver is very surprising from the perspective of physics. Everyone in freshman physics learns that the optimal launch angle for a projectile - the angle that makes a ball fly the farthest - is 45 degrees.
Does higher loft reduce slice?
A higher driver loft can help a slice because it will help to encourage a bit more forgiveness and backspin on the driver. These features of a higher lofted driver are going to help improve a slice and straighten out overall ball flight. A slice is often caused by a bit too much side spin being applied to a golf ball.

Is 9.5 or 10.5 driver better?
The ideal driver loft depends on your swing speed and the attack angle. Average players that swing the club less than 95 MPH will likely find that a 10.5-degree driver performs the best. Better players who can control their drives and want the most distance will lean more towards a 9-degree driver.
Does increasing loft open or close the clubface?
When you lower the loft of a golf club, you are also going to close the angle of the clubface. If you increase the loft on a club, you will open the face angle on the club. This applies when you are adjusting loft on the driver as well as irons or hybrids.
How do I know if my driver shaft is too soft?

What is the CT test?
The CT test also measures the spring-like effect of a club face, except it uses a small, portable pendulum system that strikes the face with a steel ball. Sensors then read the amount of time the two objects stay in contact with each other. The limit of time placed on golf clubs is ...
Did Xander Schauffele fail the CT test?
As you may remember in 2019 ahead of The Open Championship, Xander Schauffele had a run-in with the R&A after his driver failed a CT test. During the aftermath of that ordeal, the PGA Tour implemented mandatory driver testing for the 2019-2020 season.
Is it illegal to use a CT test on a golf club?
Therefore, any golf club that measures higher than 257 milliseconds on the CT test is deemed illegal. The CT test, being that it’s just a small pendulum device, is “really easy to use,” according to Olsavsky. Actually, some OEM Tour Trucks that travel to PGA Tour events each week have a CT testing setup right in their truck.
Does the CT test always mimic the response of a golf ball?
Olsavsky’s gripe is that the CT test doesn’t always accurately mimic the response of a golf ball. “When you’re pinging [the steel ball in the CT test] a half-inch or more off-center, you get a higher response,” Olsavsky says.
Is CT testing accurate?
Due to the differences in how the tests are setup and measured, however, the CT test is not a perfect replacement for the COR test, according to Olsavsky. “What we do find is that CT testing off-center is not as accurate as COR,” Olsavsky says. “CT testing will read high, because it’s really a mechanical response versus the actual impact physics.”.
What is a CT in a car?
In this case, the culprit is usually characteristic time. CT, as it is abbreviated, is a measurement of the springiness of the clubface (a measurement of the spring-like effect, in other words). A manufacturer can unintentionally exceed the limit on CT, rendering a driver head non-conforming.
What does it mean when a driver doesn't meet the rules of golf?
The short answer: The governing bodies of golf—the USGA and R&A—set parameters that golf clubs must meet in order to be "legal" under the Rules of Golf. But just because a given driver doesn't meet those standards doesn't mean a manufacturer can't make it and sell it. It just means that such a driver doesn't conform to the Rules of Golf and, ...
Why do golf shops only sell conforming drivers?
Most golf shops only sell conforming drivers because most manufacturers only make and market conforming drivers. But some other companies, and, rarely, a major golf equipment brand, intentionally make non-conforming drivers.
What happens when a driver is unintentionally non-conforming?
When a driver is unintentionally non-conforming: Occasionally, major golf brands will, in pushing up as close to the limits as possible, unintentionally go over the limits or otherwise fail to meet the equipment requirements that are set forth in the rule book. In this case, the culprit is usually characteristic time.
Why don't golfers use drivers?
But most golfers won't use such a driver because of the stigma of using a club that breaks the rules.
What does it mean when you can't find your driver?
If you cannot find your driver on these lists, that probably means the driver is non-conforming and, therefore, cannot be used in tournament rounds or other rounds of golf played by the rules. If you cannot find your driver on the list, contact one of the governing bodies to inquire.
Can a driver play in a golf tournament?
It just means that such a driver doesn't conform to the Rules of Golf and, therefore, is not allowed for use in any rounds of golf played under the rules (tournament rounds and handicap rounds, for example).
What drivers are over the USGA limit?
Drivers deemed over the USGA's limit for springlike effect included the first versions of the Nike Sumo2 and a single version of the Callaway Big Bertha 460 driver (the 13-degree HT model). At least two others were being investigated at press time.
Who is the USGA technical director?
Dick Rugge, the USGA's senior technical director, began an investigation of the problem when another manufacturer offered evidence that several rivals were producing a percentage of their clubs over the limit.
What is the adjustability of a driver?
The adjustability of the driver will play a big role depending on the skill and the personal preferences of the player. Some players prefer to tinker with the setup on a regular basis, whereas others are more inclined to take standard options and concentrate more on the workability of the ball.
What is the role of the length of the shaft in a golf shot?
The length of the shaft plays a role in the consistency of the shot and strike. Have the shaft fitted for length and you will continue to reap the benefits.
What is flex in golf?
The flex of a shaft can be defined as the rating of the ability to bend during the golf swing. The strength and swing speed exerts a variety of stresses on the driver shaft affecting the optimal distance and direction of the golf ball.
What is the M6 driver?
The M6 is an all-round offering that is one of the easiest drivers to hit currently on the market. The combination of soft looks, stable head, great sound, speed, and forgiveness will suit the majority of mid to high handicap golfers.
Is the Titleist TS range better than the 917?
The TS range is a major improvement on the 917 range with increased feel and performance. With TS range, Titleist is back in contention regarding distance whilst continuing to have consistency.
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.
How is COR calculated?
The club speed after impact is subtracted from the ball speed after impact. This is then divided by the club speed before impact.
How is COR measured?
To measure COR you need to launch a ball at the clubface. The speed velocity of the ball before and after it has made contact with the clubface is then measured. This is a complicated test to run so the R&A introduced a measurement called Characteristic Time (CT) to measure the elasticity of the clubface.
How does COR effect driving distance?
Whenever you hit a shot there is always some energy lost when the club hits the ball. At impact the ball is compressed against the clubface and can squash up to 30% of its diameter against the driver face. This is where the energy is lost.
Who is the golf channel chief technical advisor?

What is the rule for golf clubs that are straight?
The rule requires that a shaft must be straight. If it is accidentally bent in the normal course of play (not in anger) the player may continue to use it for the remainder of the round even though it does not conform, or the club may be repaired without delaying play.
Why do you cover your golf clubs?
The only reason why anybody covers (head covers) their clubs is to protect them. Generally the putter and the woods are more likely to get dinged than the irons and this is the only reason for covering (protecting) them, not to keep a hot driver hot.
