All the universities now have all the latest greatest, but you in particular Jason, you love this tool, TrackMan. It teaches you a lot of stuff about your swing, what you're looking for. What we'd like for you to show us is how you use it, and what are you looking for?

Yeah, definitely. I think it reinforces what I'm doing in my practice, and gives me some numbers that I can make sense of things, why the ball is doing what it does. I feel like that's one of the best things TrackMan does. It gives you information, and tells you why the golf ball is doing what it does, good or bad.

For people that don't know, the TrackMan phenomenon was built for missiles that were shot of boats, and they could track them, and give them data back to build their missiles better. And in our case, you're hitting missiles essentially. But you actually have one of these in your repertoire. And you actually have a cell phone. You can actually go on the course, on tour, in the practice, and say to yourself, OK, what am I actually getting here from this wedge, or this seven, et cetera.

Definitely. It's very versatile. It has a lot of different uses. I've got a 60 degree. And when I'm working with the wedges on this, I'm looking at a couple specific things. I'll hit one first and then we'll maybe go look at the screen here. So it goes back to--

This is your 60?

Yep, 60. I'm going to try to hit this about 50, 60 yards.


So the ball comes off. And when I'm looking at these-- 60 yards.

So you said you hit it 60.

60 yards. So big numbers for me with my wedges-- I want to look at two things, really. If I'm working on distances, it tells me exactly what it's carrying.

Seeing if you're way off or not?

So exactly what it's carrying. I like to look at spin rate, because this tells me--

If it's going to stop.

If it's going to grab. And what I look for is a 1.5 or better ratio. So what does that mean? If I hit it 50 yards, I want it spinning at least 7,500.

So one and a half of sevens.

Here I hit this 60, which would be 9,000. We're right at 9,000. That's right where I want to be.

And let me ask you this.

And anything higher than that is even better.


Because of the height I hit it at. You can see this height is pretty low. That's 27 feet. So I'm hitting that one that's coming in low--


Skip, stop.

And of course, people that don't know you and your idea about the way you play the game, you love to make your wedges stop.

Yup, I'm the drive it in there, skip, and stop. That's stopping.

What is stopping? I mean, we all know that we're measuring backspin. What's not stopping?

If you had a carry number of 60, and you were in the 4,000s, 5,000s--

Like a bowling ball.

Yup, not going to grab. This smash factor would be under one.

So a smash factor is an accumulation of all of these numbers, and they come up with how quality are you doing it.

It's basically your club head speed and the ratio to your ball speed. So how efficient where you transferring--

The energy.

The energy into the golf ball. So the higher this number is-- usually with a wedge like that, you're looking at something over one. You'll be pretty good.
