Is the skytrak auto level feature utilized in TGC 2019?

[MrRicker]

I've noticed that the skytrak range works better than TGC 2019 when the skytrak is slightly out of level. I've always relied on the auto leveling of skytrak because it has been within the tolerances. I built my own custom metal cage with bolts to adjust height and level. Friends used it and the legs got lengthened on the front of the skytrak. I noticed that when I was playing TGC 2019, my shots we're reading substantially more left than the skytrak range and the spin axis was rotated which created this effect. I'm assuming TGC 2019 doesn't utilize the level feature because of this.I've ordered a bubble level so It's level from now on... Just curious if anybody knows

How do you know the SkyTrak is slightly out of level? There is no "auto-leveling" feature in SkyTrak - check the level from the main screen with the Level icon in the lower right corner. Don't trust the bubble level, because the internals of the SkyTrak may not match the case. Once you have the levels zero'd out in the app, you can mark the position of the bubble with a sharpie so you can then trust the bubble level. (SkyTrak units come with a bubble level, but at least half of the units are not level in the app when the bubble level is centered.)

How did I miss this - I followed alignment Instructions on your site - just checked sure enough step 2 there it is, now I'll have to double check everything. Thanks btw your articles have been extremely helpful.

I think we are just using different terminology. As I understand it, Skytrak does not "auto-level" but it does "auto-correct" for being slightly out on tilt and roll. I believe it does by simply accounting for and compensating for the tilt.

I think MrRicker was wondering if this auto-correction is not applied by TGC2019. Auto-correction must happen before ball data is handed off to TGC2019, and I cannot see why it wouldn't be.

Good point if true. Do you have a source for SkyTrak auto-correcting when tilt and roll are out?

[Morini]

It is true. Skytrak_seth has commented about this on this forum multiple times. I believe I read it in some type of official documentation, but can't remember where. It definitely was on the Rapsodo website when they had retailed skytrak, but they have removed those. I believe it stated that it can compensate for tilt and roll to 2 degrees. I think seth mentioned up to 5 degrees, but not sure if that is what he actually meant.

that's what I was referencing... the auto-correct, which I've read about in a few different places in the last year. I spend virtually zero time setting up my system. Grab it out of the box, throw it in my homemade "armor" and start playing. Never even considered the auto-correct portion of the data not being exported but my shot shape/ spin-axis definitely was different when the front of my "armor" was tilted towards the ball. I purchased a level and am going to be more disciplined with my setup... seems to me we are all as confused about the 3rd party software as I am.

The way I understand it, it does not compensate for tilting as there is no need. As I explain below, but imagers are pointing in the same direction, so it won't make any distance if the unit leans towards or away from the ball. Though I imagine that it is most accurate overall when set up neutral, as leaning will obviously affect vertical field of view.

I know it is out of level because when I stood back, I could see that it was tilted towards my ball noticeably. My custom skytrak case I welded has bolts that let me adjust the height. The front two bolts were shorter and it was tilted towards the golfball. My start line in TGC started significantly right and I attributed this to the spin axis reading incorrectly because it being out of level. I've since purchased a bubble and am being more disciplined with setting up my system and monitoring. I will now definitely do as you advised and mark my bubble with my skytrak's zeroed out leveling through their application

When I set up my Skytrak earlier this week, in the level (after I clicked on it) it says Skytrak is designed to compensate for up to 5 degrees tilt/roll. I set mine to zero on both anyway, since it was so easy to do.

[Morini]

Thanks, I knew I had seen it somewhere. And seth specifically mentioned up to 5 degrees. It is quite simple in that sense. The skytrak measure launch angle relative to the sensors. And then information from the built in accelerometer accounts for slope of the sensors and converts to VLA against horizontal. With regards to spin axis, I don't think it matters as both imagers are pointed in the same direction, and any tilt would affect both equally so no need to compensate. If all that makes sense.
