When hitting shots on the GC2 setup its showing left spin of over 1000rpm all the time. The ball is drawing on the range and virtual course but I know when I am on the real course I tend to hit a slight fade. Anyone else experienced this? Thanks

Make sure the GC2 face is parallel to your intended line of flight. Remember everything is relative to the placement of the GC2 i.e. it measures everything relative to itself not to where you think you are aiming.Originally posted by 777Driver View Post

Take it to the range and see.
Probably just indoor swing syndrome like countless others.
Lots of people swing differently indoors versus outdoors subconsciously for a while until they get used to indoors.Comment

Thanks guysComment

That is not true. Spin computations are based on the displacement of ball dimples in the captured images. Tilt the camera vs what you think is straight and you get different displacement angle displacementOriginally posted by JackedUpSwing View Post

I disagree with the above and agree with JackedUpSwing . Alignment should only effect side angle, not spin axis. Super easy thing to test as well... just cock the unit off to the side and hit some straight chips.Comment

I took 6 months off sold my gc2 then returned with another gc2. My knockdown wedges were spinning over 1000 hook spin according to the gc2 and yes in sim it does move more than outdoors. With that said when playing outdoors I could see that my wedges did have hook spin on them so I've worked on really trying to hold them off. If you can keep it under 300 hook spin on the gc2 your outdoor wedges will be much better than at over 1k.
you can easily take your gc2 to the range and get a feel for what is going on. Hopefully your gc2 is fine but that kind of spin doesn't surprise me.Comment

How would GC2 be accurate if you had to hit it 0.0 to have an accurate spin axis reading... I am not saying a push/pull doesn't skew the view, but to say that foresight doesn't account for this is literally insane lol.Originally posted by Celeras View PostComment

Think for a minute about how a Gc2 figures out the "spin axis". It simply measures the back spin and side spin and using simple trig computes the spin axis (arctan X/Y). Any tilting effects the images used to make these measurements. The GC2 can't correct for this as it has no method of determining your orientation relative to the launch monitor. It assumes you are parallel to the machine.Originally posted by JackedUpSwing View Post
This may or may not be your "problem" but since most everyone else doesn't see this something is wrong with your unit and/or orientation.

Imagine thinking they measure back spin and side spin separately lol. The only time they use arctan X/Y is to display backspin and side spin to the user, NOT the other way around...
Bro the ball spins around 1 singular axis. They measure the dimples moving up or down.
To the camera, the middle most simple would rotate in place if it had 0 tilt to the axis. If there was some tilt, that dimple will now start moving in a circle.
If you don’t even understand the first concept, don’t bother making assumptions about anything else.Last edited by JackedUpSwing; 05-24-2021, 02:50 PM.

Yes, there is a definite left bias and it is not an indoor swing issue. It's not the measurement, it is the FSX algorithm IMO.
A draw will become more of a hook in FSX.
In TGC 2019 and outdoor my draw remains a draw... in FSX it's quite a nasty hook.
I have learned not to try and correct my swing based on FSX. Could do a lot of damage. I just aim right instead.
I just got TGC2019 and will be using that from now on - it is more accurate to what I see outdoors.
