  • Uneekor QED vs. Foresight GC2 ball data

    I do not have an HMT so I am only able to compare ball data between the QED and GC2. These numbers were generated by QED_IGNITE and FSX 2018, which I had running simultaneously on my sim PC. I plan on doing a more extensive test, but wanted to at least get some initial data. My biggest take away from this small sample is the difference in launch angle, especially with the driver. Interestingly, the carry distance is identical on the 3rd drive that has the biggest difference in launch angle. Other than that shot, the carry distance of the QED is always less than the carry distance of the GC2.

    I'm going to ask Austin at Uneekor if the launch angle is impacted by the initial calibration of the unit, and if the readings would possibly change if I changed something in the calibration.

    Can you also post the HLA? In theory top down should be better at this than side mounted.

    QED always read more VLA.
    Side Spin is interesting, 4 of the shots had them reading different direction on spin axis.

      Side spin should be easy to figure out....go to QED software and look at the actual video of the ball spinning. You should quickly see what direction the ball is spinning. Either the QED software is reporting differently or the GC2 is picking it up wrong...but the video will tell you which.

    Nice test. Not sure what to think about the LA as you mentioned.

    Am I right in assuming that if the QED Launch Angles were lowered to the GC2 that your carry distance would have actually been further in QED than GC2?

    When talking to Austin, can you ask him how tee height may or may not effect LA on drivers?

    Overall, I think your numbers are pretty close....not sure what effects using a premium ball will have....

    I believe the premium ball would definitely improve the carry differences in the wedges.

    Side Note

    I love your launch angles on your SW....I am trying hard to get mine in the low 30's with a more driving shot....but it's hard for me....I think I need to get more weight shifted forward on my downswing.....

        rgstech wow these numbers are pretty far apart imo. could you tell which you thought was more accurate as far as HLA?

    • #5
      Some fairly significant differences, now the question arises, which one is correct? Could be the set up of either monitor in my opinion

        Measure the ball mark on the screen. Grab a measuring tape and use a right angle triangle calculator. Measure the distance off the center line and the distance from the tee to the screen. You can also do this test for LA. Accuracy of this test should be within 1/2 degree or so as long as you are within a inch of measuring the ball mark accurately. http://www.csgnetwork.com/righttricalc.html

      Setup could have something to do with it, but even if you have the gc2 mis-aligned it should get everything basically right except for horizontal launch angle. If I had to to put money on it I'd say the gc2 is more accurate as it has been validated by trackman and tour usage.

        I'm not sure about this. I've used a GC2 only once at dicks sporting goods, it wasn't registering so the guy moved it around until it the ball registered. I hit snap hook after snap hook with every club I tried. I can't really hit a hook on the course if my life depended on it.

        So setup can clearly effect the GC2, doesn't mean this one was setup poorly. I know it's been proven to be reliable.

        shwag33 maybe it could be setup then, gene438 is right you could just look at the video from uneekor and see what the spin axis looks like.

        I'd like to do that, but I can't seem to find a way to look at previous session data. I have that question out to Uneekor right now.

      While doing this type of testing, it would be good to have something to determine centerline, either a string hanging down or a laser and then you could say, the shot started L or R of the target line and confirm which unit was correct.

        I like that idea, as I have a cross-line laser that I used to setup the system initially. I'll use that on my next test run.

      The GC2 is setup correct... it's been in the sim for over 2 years and I have tape and marker lines indicating alignment. I took a while to get right when it was first setup. But, does it's alignment match up exactly with the QED? I don't know, and don't know if there's anyway to truly get them exactly on the same alignment. That's why I think the HLA numbers don't match up. I think the differential is more important than the actual numbers.

      I have found the GC2 to be dead on to outdoor golf when it comes to spin and carry. I use the Arccos tracking system on my clubs and the distances are almost identical.

        Agreed, they don't have to be exactly aligned together, but the differential should be consistent, which they are not.

          Austin from Uneekor is sending me some software updates later this afternoon and he's going to look at my calibration as well. The support from these guys has been top notch so far.

            Thanks for the interesting test.

            I've done the data comparison vs GC2 only on the iron shots based off of the guy who has done the testing, and it seems very intriguing to see the differences in vertical launch angle for wedges and driver shots. For HLA this can matter a lot in putting situation only as this doesn't affect carry distances or any other ball data parameters other than the starting point for normal shots.

            I would love to see you doing more tests and see if the results differ, so we can get more number of samples.

                Sorry... no update yet. The weather has been so nice that real golf is interfering with my simulator usage. I'm hoping to have some time this weekend to run some more direct comparisons.

                  Any updates or other tests comparing ball data between the two?

                    I sold my GC2 so I am unable to do any additional comparisons. I'm still super happy with my Uneekor QED system.
