Driver Sweet Spot

For the third video in the Bomb Your Driver series, we're going to talk about something that's very, Very important and, unfortunately, very misrepresented by a lot of what you read in magazines and what you see in commercials.

And that's the sweet spot of the driver head.

With all the super highly competitive companies out there now who are competing for your big bucks on drivers that are costing four to eight hundred dollars anymore, There's a lot of money at stake and so these companies are positioning things as best they can.

To make it seem like you're going to get a lot of benefit from a driver and there's a lot of hoopla around it.

That's not exactly true.

And today I'm going to dispel a lot of those myths and one of those is the sweet spot.

When you look at a driver, Typically, obviously, there's usually like a score line on the top that's showing you where to line up, where they want you to hit the ball.

And some score lines on the face.

So you know exactly where they're showing you, the sweet spot is.

But what's misrepresented a lot of times is the actual sweet spot.

There's golf ads out these days that say that the sweet spot is enlarged, that they have a bigger sweet spot.

But unfortunately the truth of the matter is the sweet spot is a tiny size of a pin dot.

There's no enlarged sweet spot on a golf, on any driver, on any club face whether it's an iron, a driver, what have you, the sweet spot is simply the size of a dot.

And so if you look closely here, you can see that I've actually drawn a dot on here where the sweet spot is.

Now the question that you're asking yourself is well how do you know where the sweet spot is?

And I've done it by balancing this driver head on a point here.

I've actually got a pin set up vertically to make sure it's level and it's set up in a vice here.

And you can actually balance any driver.

Head on the sweet spot at the center of the club face, which is going to help you determine the center of gravity for that club.

You can balance it both on the face and on the sole, and by doing that, you'll find exactly where the center of gravity is.

And the modern driver?

What you've found is that the center of gravity from the front to the back of the club head has actually moved deeper and deeper and deeper.

This is for basically, at the end of the day.

It's going to help you launch the ball higher because it's going to help the driver, the shaft actually bend forward more at impact.

So, We'll talk about that again later, but for now, what we need to really understand is.

There's a couple things that, once you determine where the sweet spot is, it dramatically impacts how that driver is going to play for you.

So one of the things that we talked about was the actual true loft.

Where you need to strike the ball or the roll on the club face in the last video.

And how that affects the loft and where you're going to strike the ball on the face.

What we're talking about now is that once you've actually balanced this driver head on this pin, we mark that spot, what I need to do now is determine what that loft is at the sweet spot.

Now, first of all, why is the sweet spot that important?

Well, it's simple.

The sweet spot of the club is the only place that you can hit it on the face that's going to give you one, maximum ball speed.

That's where the mass is directed directly behind the ball and it's going to, and for two, it's going to reduce, it's going to have no twisting.

So if you strike it off the toe, the club it'll twist a little bit.

If you strike it off the heel, the club will twist a bit.

And what that does is it lessens the blow, so you don't get as sharp of a blow, so you lose ball speed there.

And then two, the twisting in part side spin.

So now when the ball is spinning, obviously offline, we're going to lose accuracy and distance as well.

So once you know where the sweet spot is, it's very, very important to know how to utilize that and set up the driver properly for you.

So I have in my hands here a Ping G5 Club marked 7.

5 degrees on the sole.

Now you know from the last video that just because it says 7.

5 degrees on the sole doesn't really mean anything.

Not only are there manufacturing tolerances that allow the driver to have more or less loft than what's stated on the sole of the club, but there's also the roll.

So when we're looking at the effective loft of the club, it's usually very different.

So once I've taken the time to mark the sweet spot on the club here, which I have with this black dot, I've gone in using the loft gauge and I've actually measured what the loft is on the sweet spot of the club.

And in this case, the 7.

5 degree driver, the loft on the sweet spot where I need to hit it is 9 degrees.

So if I hit this driver the absolute best that it can possibly perform, hitting it a little bit higher on the face, it's at actually 9 degrees.

So that may or may not work for your swing characteristics.

Maybe you need more loft, maybe you need less loft, but until you get on a launch monitor, you won't know, and until you start to investigate what the clubs that you're using are actually set up for, you won't know.

So I've got another club here.

To illustrate this, I've got a geekgolf .

com this head, hand-picked, 7.

5 degrees, and then I've balanced it.

I've set it up.

I've determined where the sweet spot is, and I've got it marked here.

It's also higher on the face.

And this loft is actually 10 degrees.

Now this has more roll than the ping, so to hit this ball, to use this club at its absolute maximum capability to get the best ball speed out of it, to get the center of gravity directly behind the ball, no side spin, hit a perfect straight shot, the loft is actually 10 degrees on a 7.

5 degree head.

So now I'm running into all kinds of issues where I thought I bought a 7.

5 degree head, and I did, but the 7.

5 degree of loft is way down here, but the sweet spot is actually way up here.

So what's going to happen is the vertical gear effect is going to take place, And I'm going to get more spin, hitting it lower on the face than I would hitting it on the sweet spot.

So now we're running into a lot of complex variables that are very, very important in determining how to maximize your driver distance.

So there's another issue that we start to run into, and then I'll illustrate with another head here.

I know you can't really see this very well, but I've marked the sweet spot here.

It's higher on the face than the center, and this one tends to err a little bit towards the toe.

This is a Nakashima H-Tech head.

And what you'll find here is that now we've got another issue coming into play, and it comes into play with the other drivers that I've got here as well.

That once the sweet spot is no longer in the exact center of the club face, we're losing core, that coefficient of restitution that everybody's heard so much about.

What is this core thing?

Why is it 0.

83?

What does that mean?

Long story short, what happens when the ball strikes the face is the face actually deflects.

It actually caves in a little bit.

And what that does is it actually absorbs some of the blow to the ball so that the ball doesn't compress like a marshmallow.

Now, A lot of people think that the reason the ball compresses, or what you want it to do, is compress the ball a lot.

And that gives you more ball speed, because the trampoline effect as the face gives, launches the ball faster.

It's simply not true.

The exact opposite is true actually.

The reason that the core of the face is important is because you actually want the face to cave in a little bit at impact, a very small amount.

But what that does is it keeps the ball from compressing so much that it absorbs all the energy of the blow.

So that may not make sense at first when you think about it.

You would think you'd want it to be as hard as you could.

But what it does is think about hitting a marshmallow.

If you hit a marshmallow with a golf club, it's not going to go anywhere.

And the simple reason is the marshmallow is soft.

It's going to absorb all the energy and it's just going to smash on the face.

Well, the golf ball too, because it's soft, relatively soft, is actually going to compress a lot as well.

And so what you want to do is actually absorb some of that with the club face giving in.

And that allows you to transfer more energy to the ball.

So that's why that's so important.

When we determine the sweet spots higher or lower on the face, If we look at any of these faces here, that are marked with the little dots where we've marked the loft and the sweet spot on here, well it's no longer in the exact center of the club face.

Now we've got it actually moved higher on the face.

So technically, and if you find some that tend to err towards the heel a little bit, and this is very common now because a lot of golfers, A lot of club manufacturers are moving weight to the heel to make it easier to fight a slice.

Because the toe will turn over a little bit faster through impact if there's more weight in the heel.

And this is going to help the average golfer who tends to slice the ball.

So now we've got issues where if the sweet spot's moved over towards the heel, even a couple millimeters, we're not going to get maximum core.

So long story short, where the center of gravity of your club face is, is extremely important to getting the maximum launch characteristics for your driver.

Now the trick is you can actually change this position.

One of the simple ways to do it is to, once you determine it, you have to pull the head off the shaft to determine this and you can put it on, you know, on a pin or anything like this that I have set up here.

Once you determine where that is, you can actually use lead tape or rack glue or those types of things.

It's best to leave this to your club builder, but if you have a very experienced club builder who understands how this stuff works, you can start to maximize it.

And then you can also start to find that, you know, if your sweet spot's a little bit higher on the face and it has too much loft for you, say if you, you know, you have, you're looking for a true 8 degrees of dynamic loft at impact, with the actual club head, we're not talking about changing the shafts and those types of things at this point, but your driver actually has 10 degrees of loft, what you can do is actually put rack glue or lead tape on the head, most people use the glue on the inside because it's aesthetically more pleasing, but you can start to move the center of gravity higher and lower, left to right and those types of things, to get the loft that you're looking for at impact through changing the center of gravity.

So, bottom story is, it's a complex subject, but the important thing is for you to start to understand that, first of all, the sweet spot, not always in the center of the face.

So you may be hitting it right on the screws where you think it's dead center in the face, and one, you may not be getting the true loft that you think you're getting, and two, You may not be hitting it with the proper amount of spin, because if it's lower on the face, you're going to get more spin than you need.

For the average golfer, it's not such an issue, but for the higher speed, higher club head speed guys, it's a huge deal.

So, long story short, understand that, don't believe everything that you read for starters, and also start to do your own investigation on your club heads.

If you, you know, if you understand, if you have a club builder that can pull ahead for you and mark the sweet spot for you, and you start to get an understanding of what the actual loft is on your sweet spot, You're going to have a lot better understanding on how to get maximum distance for your driver swing, for your setup in the future, and that's what you're looking for in helping to maximize your driver distance.
