Question 7 You got that one right… At 200 fps, (Driver) club path changes 10 degrees between frames in the downswing. Zen is right on about swing direction. I cant tell you how many students think they come over the top when they hit the ball left. Video is simple not precise enough to give you a clue. Trackman and a few other teaching systems can tell you where it is and its generally a lot more consistent than you might think.

Interesting video… Don’t hit down on a pitch shot. Instead, narrow your spin loft.

Zen …... in general, I’d go along with HP in response to you’re questions (11, 12 13) Eg Fade for a heel stike, and a draw spin for a toe strike. Having said that, it would also I suspect, depend on what club you were using, and the steepness of the angle of attack neccesary to facilitate a straight shot with that club, (even from an off centre hit). HP …....... Having had several discussions with Zen on course as to how how he himself hits his fades and draws, I know only too well that you can never really tell what is going on from what you see before you, (be that in real life or on video). Put Zen on a trackman though ….. and the figures clearly show that he indeed does what he says he does to hit the shots he hits. We could all do with our own private Trackman I reckon, as most of us simply guess at times as to what went wrong … or right, for that matter.

Agree GPJ – Although we have clues, most of us don’t know what actually happened to the ball when we hit a poor shot. Many serious players are purchasing Trackmans themselves. It seems like such an advantage, should be at least a 2 stroke penalty if you are a user, maybe even disqualification. I think it should be in the same category of using enchantments drugs. Below is how the distance application works…

Thanks Mav.

How does track relate to topography issues where the lies and stance is not level?

I don’t know that they have taken that far yet, apparently they think the course is level, would love to see some numbers and what turns out to be the best way to hit the target from different sloped, would be very interesting.

I have a question… Trackman shows the most efficient launch angle with the driver at 105 mph to be 5 degrees up. However, the PGA Tour average at a comparable speed is 1.3 down. Any ideas why the best players in the world are not maximizing the distance they hit the driver?

trackman is wrong?

i am now hitting up a degree or so….. from 7.5deg down….. one thing im trying to get used to is the high ballflight!!! but the distance gains are impressive…

HeadPro, Trackman shows the most efficient launch angle with the driver at 105 mph to be 5 degrees up. However, the PGA Tour average at a comparable speed is 1.3 down. We need definition of terms. For a typical driver launch angle is about 88% of loft.

I’d offer that launch angle is a combination of both the clubs inherent loft and the angle of attack. (Perhaps HP, you meant to say “angle of attack” at 5 degrees up, as opposed to “launch angle”) Launch angle is the “result”. If you have a angle of attack at -2 degrees, but the effective loft on your driver is 12 degrees …. then your resultant launch angle would be 10 degrees. On the other hand, if you have a 7 deg driver, and an angle of attack at +3 degrees, you will also have 10 degree launch angle ….... So its the combination of both (angle of attack and effective loft) ........ that really need to take into account.

Hacky, A question if you would indulge me.. So what is the effective loft stamped onto the butt of your driver, given that in theory, you have just added about 8 degrees to your launch angle? Did you always hit it too low in the past, and is it now too high, or have you optimised it via Trackman?

Negative angle of attack, i.e. “up” only applies to a teed-up ball and implies teeing it farther forward and higher. It’s not a club-fitting parameter. A typical driver launch angle is about 88% of the loft. All of my information in this area comes from Dave Tutelman. Optimizing a Driver’s Launch Parameters

Most probably because they are unable or unwilling to physically do it without compromising an already efficient action.

Thanks for having a go at my question fellas and yes, I meant to say angle of attack, sorry for throwing you off a little. Thanks for the feedback. On Tour, its accuracy that wins the prize. I think that the pros are compromising distance to get the angle of attack to be as much the same as possible through-out the various clubs. They want to feel as if they are making the same swing with each club which means hitting down with the driver. That’s my guess anyway.

All this infor is great, but what does the student do with the info?

9 degree driver stamped…. Yes, generally pretty low, now it goes really high
long, short, left and right = ALL FINGERED |

use it to understand why you dont hit it far, use it to understand how and where you swing it, use it understand why you hook/slice then combined with a gold coach, make the changes and use it to see those changes and watch the numbers improve. Take that out onto the golf course and see your scores improve

Which means your weight is over on the target leg and the swing axis is well behind the ball through impact?

Gaz, Headpro, The tour players don’t hit up to be able to work the ball and control the ball better. As soon as you start trying to hit up the collison dynamics changes and the ball can go any where on you. I switch off to all the BS they carry on about with the numbers, The rest pay no attention to, if you improve these three areas the other numbers take care of themselves. TM is a great tool although can be very dangerous in the prospective getting lost in all the numbers. We also have to bare in mind it’s a Ball Flight monitor, they are only making predictions what the club head is doing, they can’t truly measure the club head either. The numbers can be incorrect at times. However it’s a great tool to give us a guide in the right direction on what the club is doing.
