TrackMan VS GC Quad Indoor Testing

SGT is back to filming! After being away and moving locations we have come back with a bang. In todays video I put TrackMan up against GC Quad to see which performs better in an indoor setting.

Great video! Club data is a no brainer. Quad accuracy is umatched due how different both technologies work. Indoor I would say that Quad is clearly ahead overall. Outdoor things set closer

Great to see you back master Greg love all your stuff.

[joshuawilliams-ibyo]

So glad you are back! Was worried! Hope you get to the new Titleist irons soon!

Seems like there was a discrepancy in angle of attack. Would like to see a comparison with AoA, club path, and face to path side by side. Not really worried about spin or calculated carry..cheers

Quad takes several pictures of ACTUAL impact so if I were a betting man regarding strike locations, and spin based on face to path and face direction I would wager that quad is more precise indoors.

could you do this test again but outside on a driving range? Would be great to see how both pickup vs actual ball flight. And try to hook/slice a few to see how they pick those up outdoors as well. good stuff!

new digs starting to shape up nicely, might be coming back to you soon as my Wilson CBs have arrived and I'm not convinced they've got the lie angles right at the factory...absolutely loving the Nippons you fit me in by the way, I've finally got my swing dialed into them and shot one of my best rounds of the year on Wednesday, cheers and thanks again!

Hey mate, welcome back & loving the new studio, looking fwd to the upcoming content. Q- do u offer any tips / advice on golf swing (remotely-I’m in Bris)? Trying to get driver speed up from 90mph to 100-105mph & have always been interested in your effortless & effectiveness swing in achieving 100+ club speed….trying to make big changes with my swing but speeds are not improving

[paulmcmahon]

thanks for the video. I think you were comparing total spin (spin rate) on trackman vs backspin on the quad. That's ok when the spin axis is low, but it isn't always low.

[Timski]

At 4m indoor ball flight with velocity of 112mph at 5200rpm the ball will complete 6.8 revolutions by the time it hits the screen in 79ms. So more than enough data for Trackman. It’s limit of needing 2 revolutions will be anything above 160mph and 2200rpm (2.025 revolutions at 4m in 56ms)

[danschiavello]

We need a video tour of the new digs, Greg.

Angle of attack difference generally caused from Trackman reading the COM of the club head, which is still coming down relative to the face at the moment of impact, where quad reads the face hence the more upwards AoA

[leomode]

Thank you for the comparison video. May I know your distance from ball to the screen? At least for spin axis reading, the longer distance the better so I was wondering. Also after using RCT balls, have you still encountered any italicized total spin readings for Trackman? Thanks.

I play on trackman all the time, your data seems way off, like your at below sea level. Take for instance pause it @ 12:30, you have 99.6 club speed, 146.6 ball speed, 1990 spin rate, 11.2 launch angle, 1.47 smash factor, with 202.8 carry & 237.9 total?? Your settings must be off or your trackman has an issue. I play on it all the time, a couple days per week and with those numbers carry would be 245-250, total would be 270-275. I don’t like quad, last time I played on quad I got super deflated spin rate numbers and inflated carry numbers that would never happen on trackman or on the golf course. For instance, on quad I was hitting driver 96 mph swing speed, giving me 1, 400-1, 700 spin, 1.52 smash factor (which is impossible) with 295 yard total. My swing speed is right around 100 or a couple mph less. I definitely don’t drive the ball even 270 yards on the course, trackman usually reads my drives somewhere in the neighborhood of 265-270 which I think is more feasible.

How do the machines know where the ball is contacted on the club?

[tlux]

You keep saying you’ll never really know, of course you can if you bring them outside with a helper & range finder?

[kourt]

Ive used both extensively. Quad is 100% better indoors especially with higher speed players. Trackman was really bad factoring gear effect. You could hit that bad toe hook and trackman would register a push fade. But as far as use for instructors i think trackman has way more to offer. If i was outdoors or an instructor id use trackman, if youre a fitter thats indoors, quad for sure

[myopenmind]

You need to look at the standard deviation for some of those shots. There may not be the differences you presumed.

[russellfothergill]

With the driver diff this is all down to algorithms. Would tend to trust trackman more as got a lot of data from outdoor testing to base on. Quad known for being bit generous on low spinners

[tomhammond]

TrackMan is more accurate with driver carry. Foresight is notorious for inflated driver carry numbers. I owned both for quite some time, and TrackMan was more accurate all around when using RCT. Impact location was also more accurate on TrackMan. Quad is also awful on AoA as confirmed with machine vision. Quad is also well known for being slightly draw biased. I know Quad owners don’t want to admit it, but TrackMan is more accurate especially when using RCT.
