Club Path - Foresight vs Trackman

[icemann9]

Does anyone know if club path data is captured/calculated differently between Foresight and Trackman?  I have a BLP unit, which indicates that I have an in/out path; however, at a recent retail fitting using Trackman, it showed an out/in path.  Today I took the BLP to the outdoor range and used the alignment feature to get everything straight.  The BLP data showed in/out path on the display, but I noticed my divot was pointing left of target.  I’m trying to fix a pull draw/hook, so I would like to have accurate numbers to work with.  

 

I’m just confused if there is an issue with BLP accuracy, the units capture data differently, or am I going inside/inside with my swing, if that’s even possible?  Thanks for any help or insight with this.

What club are you using to compare? Units do capture the data differently. Trackman is measuring the center of mass of the club with the radar.  BLP is capturing the sticker on the face of the club with the cameras. Possible that the sticker location and the center of mass are different enough to create some difference. Wouldn’t think that much though.
 

What kind of difference are you noticing? Are the horizontal launch angles matching? 

The other difference is BLP is measuring at first touch while Trackman is measuring at max compression. So Trackman is measuring the impact point a bit later.

Measure point

Unfortunately I don’t have the Trackman data, but I was testing 7 irons.  I could be mistaken, but I thought there was 3-4 degree difference.   It was enough of a difference that I had to ask the fitter if that was right.  

 

Today I tested a 7 iron on the range just to see if maybe it was a indoor setup issue.  I saw club path recording I/O 2.6 (avg)  with launch direction showing left (and divot was left of target).  I know I have a swing fault, just kind of surprised the unit shows in to out, but results seem to indicate out to in.

I’ve seen one other post in another forum where the Foresight unit was approximately 4 degrees more in to out compared to Trackman. As long as it’s consistent you can work with it.

4 degrees is an awful lot though. I'd be pretty frustrated with those sort of numbers, particularly if his divots are pointing left. Think I'd try to check against someones Quad or another BLP.

Maybe you could post a video of your swing?

 

I'm not a pga pro, but I've seen some folks that swing under the plane and at the last second they sort of flip left. So from the down the line view, you would say they are swinging in-to-out, but the divot will point left of target.

 

I wonder how the LM's read that type of move.

That’s an interesting thought.  I’ll have to look into that next time I have a chance to record my swing.  

 

Thanks to all for the responses.  I’m sure it’s a swing issue or alignment issue, but was just curious if this data is captured differently.

I would look at issues with you vs tech if I had to check. 

 

First, many people make tweaks one day to the next and not realize. Moving ball location, hip rotation, whether you are shifting weight in the downswing will all make it change. 

 

If I had to guess. Someone who has a draw and hook issue often have a chicken wing issue where they stall in their hip rotation so the lead arm bends around impact cause the divot and ball flight to change. Just guessing as both devises have been tested many times and are pretty accurate. 

 

Could also be a device issue as mentioned. 

 

Just guesses of course

You nailed it with my swing issue.  I do stall at impact, with a chicken wing issue.  That’s what I’m trying to fix, without success.  But that’s for a different topic post, lol.

I only know cause it's me too.

You can have a positive path to the ball (in to out) and still have divots that point or curve left. Just depends on your low point and ball position. I've found Trackman to be more accurate (reliable) with club path because the setup for Foresight units leaves a wide margin of error. For example if your target is 200 yds down the range and you have the eye ball the alignment stick there is almost always going to be error. Trackman lets you use the camera to drop the target line exactly where it's supposed to be.
