Think about it like this: A high MOI golf club is like a four-door sedan, while a lower MOI club is like a sports car . The four-door sedan is easy to drive and control going into turns. The sports car, on the other hand, allows the driver to take tighter turns at faster speeds, but it’s more difficult to control.

Is high MOI good for golf?

For most golfers, high MOI is a good thing. Typically, when a golf ball is hit on the toe of a club, the face gets twisted open; when it hits the heel, the face gets twisted closed. The result is a golf ball that flies offline and with less speed.

When using golf clubs, you must use the high moment of inertia. If you want your golf club to avoid a minimum of penalties, you choose clubs with a high moment of inertia.

Who Should Use Low Moment?

If batting competitions aren’t an issue for you, you indeed won’t be forced to use clubs with high moments of inertia .

MOI in Putter

The putter technique is one of the essential techniques in golf. In particular, the MOI in the putter plays a significant role in getting the ball closer to the hole.

FAQs

You can easily see that MOI or moment of inertia is one of the most critical factors for a golfer. That’s why you need to pay attention in choosing whether you are suitable for clubs with high or low moments of inertia.

We hope that this article has helped you find a suitable answer. Happy Putter also covers many of the essential information you should know about this concept in golf.

What Is MOI In Golf Clubs And Why It Matters

The engineering that goes into modern drivers is just mind-blowing, clubs are developed more like formula one cars than golf clubs these days. Manufacturers genuinely use wind-tunnels to test the perfect aerodynamics of the head.

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.

How Is It Measured?

The USGA has a limit on MOI of 6000 grams per centimetres squared. If you look at the units there, you can start to get an idea of how this is measured. MOI is a measure of the force required to make an object rotate around an axis.

How Does it Affect Performance?

The higher the MOI the more forgiving the club. We’ve already established this, however, there is no such thing as a free lunch, as they say, so something must be lost for this gain. In general, as MOI increases, distance decreases.

High vs. Low MOI Pros and Cons

High MOI means more fairways hit with the cost of distance. Low MOI means more distance but reduced control of the ball on off-centre hits. If you are playing a low MOI driver your off-centre hits will become wilder shot shapes and misses.

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.

Who Should Use Low MOI?

Players who are consistently good ball strikers will benefit from low MOI.

Why do golfers have high MOI?

This is because they want to retain the ability to work the ball left and right. A higher handicap golfer will be more likely to be trying to hit the ball straight and is more likely to miss the centre of the club face – so they will benefit from high MOI in an iron.

What does high MOI mean?

It is also not going to set off straight. So when golfers leave putts short it can often be because they haven’t struck it out of the middle of the face.

What does MOI mean in golf?

MOI stands for moment of inertia. It is measured in grams per centimeter squared and calculates how much resistance to twisting golf clubs have during the swing. High MOI means more resistance, which means a more forgiving club (this is why you want higher MOI clubs). As you know, forgiveness is key to having more fun and shooting lower scores.
