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

[tourneychamp23]

I was informed that the distance issue with gc quad on long clubs especially the driver has been fixed in a software update about a month ago. Does this data reflect that?

This was done before a month ago

Ive never heard of a fix yet. The firmware has been the same for the past year or so. I was told that they were going to release a new firmware last week but no news yet.

I am wondering how the Flightscope matches up with these units?

Great write up Leo Mode, thanks so much. I really like playing on TGC, so am loathe to purchase a GC Quad, unless ForeSight opens it up to 3rd party software. My room is 17.5 feet long, so I might be able to squeeze a T4 in, but I was wondering, in your tests, what % of shots failed to register with T4 indoors?

I currently use a skytrak, and am frustrated with the number of shots which fail to register (maybe 5-10%). Also, the % increases when a left handed hitter is hitting over the skytrak (too much trouble to switch it from right/left during play).

My ball speed is around 145-150 mph max with driver. I have 10' from ball to screen. Would T4 allow me to demo a unit before purchasing?
Thanks for any info.

TM would allow you demo before buying and they may give you a trial period.

17.5 feet is likely the bare minimum but if you have .5 feet from the wall to the front of the unit and then 1 foot from wall to screen this only leaves you 16 feet for measurement. With 7 or 8 needed from unit to hitting area this gives less than 10 feet for ball flight. TM recommends 19 feet min length so you just don’t have the space unfortunately.

Hey Dax, 17.5 feet is from back wall to screen - I am planning to embed the unit in the wall, making an enclosure, almost like a shower enclave, so maybe it’ll work! That’s great re demo from TM, will contact them. Thanks so much!

I posted a chart from TM some time ago I think regarding the min distance required for spin and ball speed. I am sure TM can provide you a copy of that chart. It is for driver reading and given that you are going for the bare min of distance, I would make sure it works for your swing characteristics for the space you have. Otherwise you will be very frustrated hitting shots and not getting a reading.

Outstanding analysis.

[Wang]

I always understood the limitation of the gc2 for spin axis was because it is viewing the ball from the side for such a brief period of time. Think about how subtle that spin would look in only a foot from that angle. We may be talking about 1/8th of a sideways rotation for instance- and the angle changes during that period as the ball moves away from the unit.

In contrast, velocity, launch angle, and backspin are all ideally calculated from that angle with 2 or more timed snapshots.

To lower the error on sidespin, you'd need an angle from the other axis, either behind the ball or above. Neither of those is practical.

Reread some of above. For GC2 : "ball algorithm gets calculated separately by the software so GC2 carry is not reflected in the game which is nice"

Why is it good that GC2 carry is not used in the game, instead calculated by software?

[Wang]

I would think it has to be that way since the gc2 doesn't know if it's an uphill shot, into the wind, out of the rough, etc.

1) GC2 carry has inflated distance algorithm that needs to be fixed.
2) GC2 carry is only at sea level with no wind (i.e. bubbled environment). Sim software has multiple variants in environment conditions.

It’s because most think driver shots below 2k spin are too optimistic in foresight’s calculations. So most feel that TGC and others calculate driver carry better than foresight does.

Plus it’s good that everyone playing the same sim software is using the same physics for ball flight.

[Solstice72]

Thanks for the answers guys. 🙂

[mthunt]

The reason GC2 carry is not used in the game is because the game uses it’s own algorithm based on Launch, ball speed, direction and spin. Carry is not used for that algorithm
