What does Moi do in a driver?
An acronym, MOI stands for “moment of inertia.” MOI is measured in grams per centimeter squared and shows how much resistance a clubhead has to twisting. The more resistance it has, the higher the MOI reading and, importantly for golfers, the more forgiving the club will play.
What does higher MOI mean?
MOI is an acronym that stands for “moment of inertia.” This measurement (grams per centimeter squared) shows how much resistance a clubhead has to twisting. The higher the MOI reading, the more resistance it has and the more forgiving the club will play. For most golfers, high MOI is a good thing.
What does high MOI mean in golf clubs?
A high MOI means that the club is more stable and therefore more resistant to twisting, which translates to more ball speed and a straighter shot. So for the average golfer a high MOI is beneficial as it will lead to consistently straighter and longer shots from off centre strikes.
How is Moi measured in golf?
The bigger MOI causes the more torque it will take to produce a certain amount of rotational acceleration. Moment of Inertia is defined by the mass and the axis the mass is rotating around. Quantitatively, the moment of inertia of each grain of mass is its mass times the square of the distance to the axis.
How do I increase driver MOI?
Adding weight, or locating weight more to the perimeter and/or rearward can raise the MOI, but by an amount that most players may or may not be able to notice.
What loft driver should I use?
Choose a loft to try based on your assessed club-head speed. If it is between 95 and 104 mph, a 10- or 11-degree loft will be appropriate. If it is between 105 and 115 mph, a loft between 7 and 9 degrees should be considered. Golfers with club-head speeds below 85 mph should use a loft angle between 14 and 20 degrees.

Are steel shafts better than graphite?
Typically, steel shafts are much heavier, more durable and are generally less expensive than their graphite counterparts. They are more often than not made from stainless steel and they tend to weigh in between around 90g-120g. Torque or lateral twisting found in all graphite shafts is lower in steel irons.
What does workability mean in golf?
Workability is not just left and right curves, it is also the ability to control the trajectory. The golfer doesn't need to know how or why but only what.........so if the club is designed to help you get the ball in the air, then you can conclude it will be harder to keep the flight down.
What is MOI matching?
MOI Matching is simply a replacement for swingweight matching in the fitting process. Clubmakers will fit golfers for every one of the other key fitting specifications based on the same fitting procedures that they have developed and with which they are experienced.
Should all my clubs have the same swing weight?
All of Your Clubs Should Have the Same Swing Weight Even if you think your clubs are a bit light or heavy for you, all the clubs in your bag should at least be very close to the same swing weight. Using clubs with different swing weights typically leads to poor performance on the course.
What does golf term Moi mean?
moment of inertiaGenerally known as MOI in the golf world, moment of inertia is basically the measure of a clubhead's resistance to twisting when a ball is struck away from the sweet spot. This means the higher the clubhead's MOI, the less it will twist and the straighter the ball will fly on a mishit.

Well, with a driver high MOI can often result in higher spin and higher launch if a lot of the weight is low and back.
What would happen if the ball was to strike the toe of the driver in a club with low MOI?
If the ball was to strike the toe of the driver in a club with low MOI it would twist the club face open away from the target.
What is the difference between MOI and forgiveness or stability?
Nothing. They are effectively the same thing. High MOI means high forgiveness and stability.

High MOI putters are popular among tour players and handicap golfers for the same reason. Even the pros need forgiveness on putters – it could be the difference between winning and coming 2nd.
Do tour players want iron heads?
With irons, I’ve heard club designers and and tour technicians say that tour players want their iron heads to have low inertia.
Is Ping a high MOI?
Ping are huge believers in the importance of high MOI and will often make this their focus – rather than distance – when releasing a new driver.
What is MOI in golf?
One feature that has had to be reigned in by the governing bodies of golf, the USGA and the R&A, is moment of inertia (MOI) of the head. It is a physics term that refers to an objects resistance to twisting about an axis. More on this to come.
Why is low MOI important in golf?
One of the big benefits of low MOI in golf clubs is the ability to shape the ball. If you have the skill to make the ball move at will then low MOI is useful. High MOI makes it much harder to shape those drives round doglegs , etc.
What Exactly Is MOI?
During those microseconds of impact during the golf swing, your clubface twists. If you hit it out the middle it doesn’t twist but off-centre hits can cause pronounced twisting. That movement can contribute to wild shot shapes like snap hooks and slices.
Who Should Use High MOI?
High MOI is best for golfers who really need help to with forgiveness, players who find it hard to hit their clubs out the middle.
How Much Should MOI Affect Your Choice of Clubs?
This depends on what your biggest issue is in your game. If accuracy and consistency are factors that you really struggle with, then MOI should be very much at the fore-front of your thinking around what clubs to buy. Getting this right could be a game-changer.
Why are MOI limits pushing?
Manufacturers have been pushing MOI limits for years in order to make it easier for golfers to hit.
What does a lower MOI do?
Lower MOI will give you more distance and will also give a great ability to shape the ball.
What does MOI mean in golf?
The acronym "MOI" stands for "moment of inertia," and in golf MOI is a measurement of a club's resistance to twisting.
What is the MOI of a golf club?
MOI of the whole club around the golfer: As stated earlier, the whole golf club also has an MOI. The longer the club, the heavier the head, the heavier the total weight of the head, shaft and grip added together, the higher the MOI will be for the whole club.
What is the MOI of a clubhead?
MOI of the clubhead around the shaft: The second example refers to the MOI of the clubhead about the shaft axis. Little is spoken about this MOI in equipment marketing, but it is an important head design factor that can affect the accuracy of the shot, not the distance. The bigger the head or the more weight that is placed far out on the toe of the clubhead, the higher the MOI of the head will be about the shaft's axis. The smaller the head or the more weight that is positioned in the heel area of the head, the lower the MOI of the head will be about the shaft's axis. The higher the clubhead MOI around the shaft, the more tendency there is for a golfer to leave the face open at impact. The lower the clubhead MOI around the shaft, the more tendency there is for a golfer to rotate the face more closed at impact.
Why is a higher MOI clubhead more resistant to twisting?
But if the moment of inertia can be increased, the club becomes more resistant to twisting. Therefore, a higher-MOI clubhead will twist less on off-center strikes than a lower-MOI one, meaning less loss of distance.
What is swingweight matching?
The current method for matching clubs in swing feel is called swingweight matching. Swingweight is an expression of the ratio of the weight in the grip end of the club to the weight in the rest of the club on down to the clubhead. Swingweight-matched golf clubs are not matched for MOI, but come relatively close to MOI matching. MOI matching of clubs is a swing matching system currently offered only by more advanced custom clubmakers.
How to determine MOI?
Remember, MOI has to first be defined by identifying what axis the object is rotating around. There is an MOI for the whole golf club which, when swung, is "rotated" around the golfer during the swing. There are also three different MOIs that can be measured for the clubhead itself.
Why is MOI important in golf?
The MOI of the club is important to matching the swing feel of all the clubs in the bag. Clubfitting theory states that if all clubs in a set are made to have the same, identical MOI, the golfer will be more consistent because each club will require the same effort to swing.
What does MOI mean in golf?
CG or COG means Center of Gravity. MOI means Moment of Inertia. The former controls launch and spin conditions. When CG is placed farther back and lower, it increases MOI and leads to a higher launch. In simpler words, more forgiveness on off-center shots.
Why is MOI important in golf?
The real question any golfer should ever be asking is why is MOI important in golf? Look, if you’re a beginner, high-handicapper, senior, or even a female golfer, then your topmost priority is to make sure the golf clubs you currently own are highly forgiving. This way, the chances of hitting the sweet spot for striking away are the most likely. And that can only be achieved through high MOI.
What does it mean when a golf club is on the fairway?
Hitting tee shots consistently down that fairway has a direct connection with the MOI of your golf club. With high MOI, where the weight is placed farthest away from the clubface, twisting is minimized. This means the clubhead is squared at impact for higher launch and topspin despite an imperfect swing.
Why do golfers use cavity back irons?
Meaning highly-skilled golfers expect more workability from their equipment. Now you know why they go for sleek cavity-back and blade irons? For an experienced player, generating well-controlled mis-hits just to advantageously exploit launch and spin is both essential and easily attainable for veering the shot to the right or left. But if high MOI is a part of that manipulation, then everything goes for a toss.
How to increase MOI?
The most common and effective approach to increase MOI – placing weight around the perimeter (edges) of the clubhead. With super game improvement irons, this is exactly what makes them magnanimously forgiving.
What happens if you hit a low MOI?
In such a scenario, your mis-hits turn into exaggerated blunders and wilder-shaped shots.
Why are golf drivers not easy to hit?
The thing about golf drivers is that they’re not the easiest to hit because of the long shaft and small sweet spot. But then top brands like TaylorMade, Callaway, Cleveland, Wilson, etc. are pushing the very limits of MOI just to make the driver easier to hit for beginner and amateur golfers. As for limiting MOI, that’s for the pros!
What is MOI in golf clubs?
But it should be acknowledged that there are several MOI's in golf clubs, for example there is the MOI of the club-head around the shaft and the entire club in relation to the golfer.
What does MOI mean in golf?
The acronym MOI means ‘Moment of Inertia’ and in a golfing context this is a measurement of a club’s resistance to twisting. When you strike the ball towards the toe of the club, the impact pushes against the toe of the face and that pushes it slightly open. The result is probably a block out of bounds to the right.
Why is MOI important in golf?
There is also a club-fitting aspect here because if the MOI is different in all of your clubs then this will hamper your consistency. It is said that if it is the same, then your consistency improves because each club requires the same effort to swing.

What happens when you hit a golf ball towards the toe of the club?
When you strike the ball towards the toe of the club, the impact pushes against the toe of the face and that pushes it slightly open . The result is probably a block out of bounds to the right. Likewise in terms of the heel, the impact causes the face to close slightly.
How is MOI changed?
MOI is improved by moving weight away from the center of gravity of the club. This helps the clubhead to resist the twist.
Is MOI only found in Drivers?
MOI can be measured in all clubs. PXG’s new Battle Ready Putters are fully optimized, high MOI clubs – ideal when you need to close out on the green.

What is a good CG position for a golfer?
The basics are simple. Forward CG positions often produce higher ball speeds, lower launch, and less spin. Back positions bring higher ball flight, more spin, and increased MOI. That last one usually leads to more forgiveness, which is nice. Extremely high CG positions are generally less than ideal, but they can benefit golfers who consistently hit the ball high on the face, while low CG designs typically work for high spin players and golfers who hit the ball low on the face.
Which Taylormade driver is the most neutral?
The most neutral driver we measured was the TaylorMade M5 (ironically in the draw position – everything is relative). The PXG 0811X GEN2 and Cobra F9 Speedback are also near-neutral designs.
Which driver has the highest CG?
The highest CG (relative to the neutral axis) of the drivers measured belongs to the Sub70 839D, followed by the TaylorMade M5, though it is worth noting that the M5 is mid-CGNA in its more forward positions.
Does the center of gravity matter in golf?
The center of gravity location of your driver matters, and not just because the golf equipment makers say so. It doesn’t matter if we’re talking about low and forward, low and back, deeeeeep, or somewhere in-between, golfers would benefit from an understanding of how center of gravity positions influences real-world performance.
Is it rare to find the perfect driver?
Finding the perfect driver is rare. As you’d expect, every design brings with it a trade-off or two. Forward CG positions often lack the forgiveness many golfers need, and there are instances where too much MOI can cause both swing speed and ball speed to drop. There’s balance in the middle, though sometimes playing it safe leads to unremarkable performance.
