Launch angles too high in TGC (SkyTrak)

[bobsyouruncle]

I'm getting consistently higher launch angles in TGC 2019 than I am in the SkyTrak software. For example:
D: 14 degrees in SkyTrak, 20 degrees in TGC 2019
7i: 17 degrees in SkyTrak, 26 degrees in TGC 2019
PW: 24 degrees in SkyTrak, 34 degrees in TGC 2019

I generally have a lower than average ball flight, so the SkyTrak numbers seem closer to the mark (especially for driver, there's no way I'm launching it that high).

ProTee say there can be no difference between the two, that TGC 2019 takes the numbers straight from SkyTrak, but there is a clear & consistent difference in the numbers I'm seeing. Searching these forums I can't find anyone else who's had a similar problem. Anyone have any ideas?

That's bizarre, have never heard of that issue. Make sure you're on the latest versions of both software packages, including the TGC SkyTrak interface. Would love to see some screenshots of shot data from, say, 5 PW shots in the SkyTrak range, then a few in TGC 2019.

If you do some math, maybe you can figure out how high up on your screen 15, 20, 25 degrees would be and put a string up to see where it impacts vs the string while you are in both software systems. Or if it leaves a temporary dent in your screen, just measure that and see if it correlates, should be fairly simple to confirm if it's that far out.

That's a great suggestion. Here's a google spreadsheet to help you make that calculation:

Thanks for the suggestions guys.

I've confirmed the SkyTrak launch angle is correct by measuring the impact point distance & height. I've also checked the numbers in E6 Connect. Here are some screenshots:






I've been in contact with ProTee, but so far they haven't acknowledged a problem. I'll keep trying.

Perhaps I should move this to the TGC 2019 forum?

Wow - that is crazy. You're right, there is no way you're launching that 9 iron at 31 degrees based on your SkyTrak range data and E6 Connect data. 31 degrees is probably where you launch you sand and/or lob wedges. Something is amiss between SkyTrak sending the data to the TGC SkyTrak interface software (which has code from both SkyTrak and ProTee in it) and TGC displaying it.

Wouldn't hurt to re-install TGC and TGC SkyTrak Interface to make sure you've got the latest versions: https://csc.protee-united.com/hc/en-...ion-QUICKSTART

I ran the TGC shot data through the FlightScope Trajectory Optimizer at https://flightscope.com/products/trajectory-optimizer/ using sea level elevation, and the carry that TGC is showing is closer to the shot at a 24 deg launch angle than the displayed 31 degrees, so maybe they're getting the right VLA number from SkyTrak and just displaying it incorrectly.

One other thought - make sure you try hitting from various locations in TGC, ideally on the range, just in case that shot was on an uphill lie or something and they're using that in the calculated display number.

A bug like this probably isn't noticed by most folks - I know I don't pay much attention to the shot detail screen when it comes up in TGC, as I'm usually more focused on playing than practicing when using TGC. But I would agree with you that you have definitely found a bug.

So this is interesting, and I actually brought this up in a thread the other day. But I too feel like my driver launches really high in TGC2019.

I don't have any data to back up the claim, and I have shot display turned off in TGC. But just from watching the shot tracer it seems like it launches high. I also feel like it carries a little bit longer than it does on the Skytrak range.

I don't sense any difference with any other clubs. Everything else seems normal. Just the driver that seems to launch high.

Glad someone else sensed this as well. So maybe I'm not totally crazy lol.

I just re-installed, and I'm not getting the right launch angles when using the beta interface. The standard interface still gives the inflated numbers (maybe it wasn't updated properly in the reinstall?). In any case, this is a solution I can live with. Thanks for the suggestion. I just with ProTee made it easier to update the software.

We just tested the SkyTrak Beta interface against GC2 and Flightscope X3. SkyTrak in right handed mode, GC2 right across in left handed mode and X3 in the back and the launch angles are all almost identical. Not sure why you are getting different results...

The Beta interface works fine, it's the older interface that is giving weird numbers.

[ProTee United]

Alright, we will run another test with the original interface and report back!

[bobsyouruncle]

Ah sorry I see the confusion - I wrote "I'm not getting the right launch angles when using the beta interface" in my previous post, I meant to write "I'm now getting the right launch angles when using the beta interface".

I'm happy to use the beta interface, but appreciate you following this up. Let me know if I can help with anything at my end.

[ProTee United]

We just tested the original SkyTrak interface and came to the same conclusion. GC2, ST and X3 all report the same LA. The LA difference we see is between 0.2 and 0.5 degrees lower/higher. The angle reported in TGC is rounded. For example GC2 reports 24.6, ST reports 24.8 and TGC reports 25 (rounded from 24.8).

Really strange that you're seeing different results. We have no idea what would be causing it.

I'm seeing different results as well in the Skytrak Range vs. TGC courses. For example, a GW will travel anywhere between 120-130, but in TGC I'm lucky to get 100 yards.

When you see this, note what all the ball parameters are and then compare them to the shot in the game. Something should stand out to have that big of a difference. Might be spin and a little ball speed

wbond It's been a while since I last jumped on the website, but today I took some time to use the flight optimizer on the sky trak and noticed i was getting really low spin numbers. The only difference was when I was using driver, I was getting higher spin numbers than their "optimal" range. I'm thinking it might be my mat that might be holding me back. I played golf this last weekend and my distances are spot on to what they've been the last couple years. Just can't seem to get near them with the skytrak.
