Distance is inaccurate with the woods

[Willymakit]

Just wanted to see if anybody else went to the range and actually tested it with the woods and how accurate it was. And what results they came up with. Well this weekend I did and I can confirm that the woods are definitely short on Skytrak.

Here's my setup on how I did it. Was on the 18th tee box and was a slow day so I tested all the woods. I had a friend stand out by the landing zone and would hit the balls and he would stand where the ball landed. Then I would lazer it from tee box to where he was standing and then lazer again on where it finished. I wrote down all the numbers from the driver , 3wood and 5 wood. And recorded what was shown on Skytrak. I can confirm its at least 20 plus yards out. From what I can tell , for example. If Skytrak would say it landed at 240 yards and rolled 20 yards for a total of 260. But The lazer would say 265 on where it landed and would roll out 20 yards to end up being 285 yards. I did this on all the woods and it seems where the end result of where the ball rolled out on Skytrak would be the distance it would land shot by the lazer on the course So in the end result I sure hope that SkyTrak_Seth reads this and can figure out real quick on a solution to this problem or I'm just going to lose interest and hopefully be able to return it for something more reliable when playing simulator.

So Skytrak I hope you get this rectified ASAP or you will lose a customer.

Were you on an elevated tee? What were the wind and weather conditions? Did you replicate those, and your altitude, into the app?

[luv2golf]

Willymakit, would of been great if you could video these findings. Most of us (myself included) take our skytrak to the range and hit balls (my range uses yellow balls and they work great, as long as it's not bright/daylight affecting the photo's).

I believe you've been made aware of some tweaks coming in app version 2.0 that will affect the yardages on the woods. I'm guessing the irons are spot on or you would of had something to say about them.

[Willymakit]

I had reported before that the irons were pretty close. I did hit a 9 and a 5 iron and it was close . Have no issues with the irons

I was on a level tee box tee to green. No elevation and no wind. It was 21 Celsius out. It was a gorgeous day out. I set the Skytrak to the same elevation and weather I had for the day.

I would have used video but there was only two of us and I was using my phone for The Skytrak.

The other thing I noticed was the height of the ball on Skytrak compared to what I was hitting. Skytrak was much lower ball flight then what It showed irl.

[luv2golf]

Gotta ask.......was skytrak level? Did you put a level on it front to back and side to side?

[Willymakit]

With the woods I get the same results inside or outside on the Skytrak . That's why today I had to try it outside to see the actual results. And nothing changed with the results. Was still at least 20 yards difference between Skytrak and irl. I was just inquiring if anybody else was having this problem. If not maybe I have a defective unit. But I figured I didn't because the irons are closer to what it shows in Skytrak and irl. But if updates don't come out soon and rectify this problem then I could see myself getting something different for a simulator.

Yea I've noticed the exact same problem with mine as well, irons are dead on while the driver is 20 yards short. I definitely appreciate hearing your test results and realizing I'm not the only one. I'm gonna test some stuff out with different orientations of the skytrak and see if anything changes, I'll report back if I find any fixes

[Zeroes]

How many balls did you hit ? Maybe your friend is not to be trusted !

[joeycalda]

My son practices on a Foresight GC2, and the pros at the place stated that the driver distances for them were always wrong I don't remember if it was short or long, but it was off by about 20 or so yards as well. It must have to do with the speed of the ball off the clubface. Now the driver distance for my son was accurate at 225-230 yards.

[HarryG]

Same here. A well struck driver for me averages around 245 on the course and I've only ever had ST report that distance once. ST reports the majority of my drives between 220-230. I have altitude set to 5000 ft to make my irons accurate.

Presumably the algorythm they use doesn't factor in which club is being used for a swing as ST measures ball data. This leaves one wondering if they know about this issue but have yet to tell us about a proposed fix. If they tweak the longer clubs and leave the irons untouched, then we would have to start specifying what club was being used for a particular shot. We can do that currently, but this feature is only related to tracking stats.

I agree with Willymakit. I've tested SkyTrak in driving range and irons seems spot on while driver seems a bit off (but harder to tell because I can't get someone to stand in the range). And playing with SkyTrak at home (I use my SkyTrak outdoors in yard - so no outdoor/indoor syndrome), driver (and woods) seem about 20 yards short. I think there have been a couple of posts (one with a spreadsheet you can download showing data of SkyTrak vs Trackman done by someone) showing SkyTrak is a little bit shorter on the drivers and woods too. I think I've also mentioned this on another post as well.

I would think there are no defective units but there are indeed some problems with their driver measurements or else they wouldn't be releasing updates in 2.0 that's supposed to correct their driver and wood distances to be more accurate (i.e., not coming up short) if the driver/wood measurements were perfect.

[Willymakit]

Thanks guys for confirming on what I already thought that Skytrak was out by at least 20 yards. When I first used the Skytrak indoors I knew it was at least 20 yards short when I could only hit the driver 240 in the air. I needed to test it for myself on the golf course when the conditions were perfect and yesterday I took that opportunity when the weather was perfect and no wind

I hit about 10 balls with each club and they were all short compared to the Skytrak. Unless my lazer and GPS are out also but I don't think so.

I just don't understand why we all don't have the same issue on the woods being short.

Like I said. I hope Skytrak rectify this problem really soon before I get bored with it. I don't have a problem dropping 10 grand on something that works.


Honestly I don't care what the charts say between trackman and Skytrak. I physically went out and performed my own test and can confirm it at least 20 yards short. Nobody can tell me any different.

[MrHogan]

if you have 10 grand to drop on something why you keep buying entry level Optishot and ST ?

[HarryG]

How would they fix this as any change would alter all clubs universally which would alter the already accurate irons?

[luv2golf]

AGAIN, I HATE TYPING IN BOLD AND CAPS, BUT I STATED IN THE BEGINNING OF THE THREAD THAT SkyTrak_Seth IS AWARE OF THIS ISSUE AND THERE'S A TWEAK IN VERSION 2.0. THAT'S WHAT HE'S STATED IN ANOTHER THREAD.

THIS IS GETTING REALLY BORING BEATING A DEAD HORSE HERE. IF YOU WANT TO FIND THE THREAD DO A SEARCH AND FIND IT, IT'S THERE.

[MrHogan]

It was in a similar thread started by the OP too.

If there is an issue with the distance, is it just the algorithm calculating the distance needs to be tweaked? Or is the issue that the measured data is incorrect with woods? If it's just that the algorithm is calculating distance incorrectly for woods, I don't really care so much. It's not like it's an iron that I want to hit a precise yardage (although an accurate yardage would be helpful to know for forced carries etc). As long as the ball speed, launch angle, back spin and spin axis are correct, it's giving me the data I need to make sure I'm launching the ball efficiently - the distance will be what it will be.

[SkyTrak_Seth]

The measured raw data is, and has been, spot on. We've identified a tweak for driver for v2.1 that will boost driver distances by around 4%,
