[FINAL RESULT] Trackman 4 VS GC2+HMT/GCQuad

[-MG-]

Thanks for the write up.

I currently own a TM4 and have an indoor room that overall length is 25' and I have the ball about 15-18 feet from the screen. I almost always have the reflective dot on the ball when I play. I continue to sometimes get questionable numbers. Many times, its the spin that is way off and it will say I just hit an 8 iron 200 yards, it happens enough that it is annoying. I only bought the indoor version. If I want to go outdoors, I will use the one my local pro has and we would utilize it during our lesson.

I'm curious if you think I would be better off with the Quad? I am not bought into any course packages as TM has been providing them out if you have a software subscription. Does foresight allow for a try before you buy? I use my TM for practicing on the range, the on course practice feature is really nice.

Is it worth it to go through the pain of trying to sell my TM and buying the Quad, or not?

I would wait until next major update in April which is supposed to fix indoor gear effect. For the spin make sure to check if Total Spin was in italics. If so it meant it was calculated. If not, unfortunately it’s highly likely that the spin number is correct and it may have to do with your mats, swing or ball.

Great info, and thank you for the write up! I'd love to get a GCHawk into your hands, they are being delivered, very curious to know how those are stacking up to the tried and true. Anyone hit one yet?

[LEO MODE]

You can send me a flight ticket and a hotel and I would test it for u with my devices as I dont want to make a hole on my ceiling for the hawk lol.

[anthonywebb]

If we could find someone with a GCHawk it would probably money well spent to put you on a plane @leo ! I'd certainly trust your review more than other "credible" sources. When you are spending $20k+ it's worth the piece of mind that the thing gets the job done well.

Appreciate your word. Just try to spread out the truth and facts only, and in order to do so you would need to experience both end of the spectrum in which I am trying to do.

Re-read this post and find the following statement interesting:

Spin Axis: Outdoor, their difference varies, especially Foresight products being more draw-biased, but also 30~40% of the time they are also fade-biased. In other words, Foresight products are very unreliable when it comes down to Spin Axis. Although they portray similar flight 2D modeling, the ball flight still doesn’t correctly reflect actual landing area. Indoor however, Trackman is also very unreliable especially when it goes up to higher clubs (i.e. driver shot) as high as 20deg. Iron shot is close to GC2/GCQ but still slightly fade-biased than GC2/GCQ.

If I read correctly, Leo is saying that neither GC2/GCQ or TrackMan can display reliable side spin/axis # therefore offline # in indoors setting; "Very unreliable" is what the test concludes. This is both unfortunate and a bit surprising to be honest - I thought GC2/GCQ is accurate for spin axis display. So, should we just ignore the offline numbers when we play indoors?

Leo -

any change in your thoughts since your review? I now have both a Quad and TM4 and I’m in between which to keep. I need FSX2020 to come out likely to make final decision. What may push me to TM4 is I have a lefty golfer in the house.

I do some of my own club building so I love having quad to measure lie angle. I have been using virtual golf 2 on TM4 and FSX on Quad.

only real discrepancy I noticed was on short 60 yard wedges backspin was sometimes around 1000RPM more on Quad. Safe to assume quad is better here?

LEO MODE just updated his latest thought in a discussion thread on the Mevo+ and spin axis. Hope he has not finished a complete testing, his comments are very helpful. I would suggest looking for that thread.

For me, I am not convinced fsx 2020 will be that much of a huge leap! The only reason for this speculation is their announcement to bring on e6 Connect. I could definitely be wrong.

Paging LEO MODE

I have noticed that there is a huge difference in Trackman vs Quad when it comes to Driver numbers. Almost by 20-25 yards in carry. I know others have mentioned the algorithm is a little over stated for Quad.

[Dax]

-MG- i think those issues were resolved. There could still be some minor differences, but can you provide more information on the set up of both units at the time of comparison?

[-MG-]

Dax My statement above likely resembles the 1 out of 10 scenario that I think Leo mentioned before. I had them side by side and Trackman always was the shorter carry. I would say that 7/10 were both within yards of each other and spin was within 100rpm. The other 3 vary from Trackman reading 2500 spin and Quad saying 1800. I believe the scenario's I am thinking about likely have the most to do with gear effect as they were hit closer to the toe and high.

Not sure what question around the setup of both units. In my basement, I have a room about 28' long, and from hitting mat to net is about 15'. Trackman is about 9 feet back of this.

[Dax]

-MG- sorry my question was more around the set up of the units to make sure target lines were identical and that things like elevation etc were accounted for (metallic dot in the ball, wind, temperature etc.).

cheers!

If indoor, Quad's backspin (Total Spin) numbers will be more representative than Trackman 4 at this moment. I've seen a few instances when Trackman said it measured spin but it was completely different from the Quad (about 1 out of 10). And I trust Quad more in that sense because outdoor, their numbers were always close to identical (even at low spins 1800rpm). For low spin Carry (less than 2500rpm) however, Trackman will always be more representative than Quad. Quad does say it did go 20yds further like you saw. It gets very generous in low spins.

To answer TrueNorthGolfer's question about Spin Axis being unreliable on both devices, I didn't mean to say Quad was not accurate. What I meant to say was Quad didn't seem to portray like Trackman outdoor on Spin Axis very similarly all the time, so although 2d ball flight was very close to what Trackman outdoor would say, the numbers themselves didn't seem so trustworthy as they seemed a bit more exaggerated (this goes align with GC2 showing more draw spins, although Quad goes both ways). For offline numbers, what I can tell you at this point in time is, you can look at wedge and iron numbers but maybe not too much on driver numbers. For wedge/iron outside, their difference was about 2-6yds which is pretty negligible imo, and indoor with the latest Indoor Gear Effect TM4 update, they're about the same indoor too now (before their difference was more). But for driver you still see some differences. Ball flight however has gotten better. Ultimately though, I never really looked at offline numbers anyway because of too many variations that can happen outdoor (wind, gear effect, spin axis differences, etc.).

Lastly, as Dax said, always use metallic dots on the ball for Trackman and have enough distance (I recommend more than 10ft) to look at measured spin numbers for the time being. I personally use two metallic dots right next to each other horizontally and it does help me get measured numbers more.

Hope this helps.

This is great info Leo. Interesting about the 2 dots. Horizontal not vertical placed?

Never tried vertical but I was told that horizontal would work best.

[Dax]

Yes in an old TM indoor set up document they actually have pictures showing how to use the two dots. I had asked Someone from support about this a couple of years ago and he advised about not doing this any more. I believe he indicated it made things to “bright” or something like that.

[Wayno]

A lot of money for inaccuracy.
