SkyTrak not registering any shots left and right / all three LEDs stay green

[ron burgundy]

Dear all,

I have recently bought a used SkyTrak unit. The seller has deactivated his account and I have registered it in my account. The seller says it worked the last time he used it. Since I used it for the first time, however, I have not once been able to register a shot. I also switched the handedness of the unit and tried the left side with the same effect. All three LEDs stay green constantly and the laser point also is constantly on.

Did anyone of you maybe have a similar problem with his unit? Or do you have any idea what might be the reason for this behaviour?

Thank you very much for your help in advance.

Best,
Christian

That's the symptom of a burned-out IR laser curtain, but it's super rare to happen to both RH and LH sides. Sounds like you may need to send it to SkyTrak for evaluation/repair.

Prior to that, go through the steps at https://gunghogolf.com/articles/skyt...ction-problems and make sure to test with just the SkyTrak app, starting with Direct mode (to rule out USB cable issues).

Thanks for your help. I have already done the steps described under the link you provided without any luck. Based on my research online and especially here in the forum I also thought of the laser curtain. However, I am very suspicious because both sides don't work. This should be quite unlikely to occur if the defects of both laser curtains are independent of each other...

They are independent components. But one DIY fix involves opening up the SkyTrak and pulling out the LH laser curtain and moving it to the RH side, so perhaps your unit had that done to it.

That is something I was thinking as well. The seller, however, says he has not done this. It has been for repair with SkyTrak two years ago, but they would not perform this type of fix I am sure.

I just took two pictures and it seems the IR curtains seem to work, as there are some rays coming from both curtains. At least it shows that both IR curtains are still there. But it could also indicate that the problem might lie somewhere else...

[ron burgundy]

That is true. As can be seen from the pictures my iPhone camera seems to pic it up as do also other cameras.

You're not seeing the IR curtains in those pics - that's the visible red dot laser indicating ball placement. IR curtains are a different bulb.

I don't refer to the laser point before the Skytrak unit. You can also see a more blueish point on the right (in right hand mode) and on the left (for left hand mode) of the unit itself. These points are exactly where the IR curtains are supposed to be. On other pictures on the web the IR curtains look similar so I assume these are rays from the IR curtains. This at least shows that they are there and emit some kind of radiation. We, however, don't know for sure that they are working 100% correct.

How are you connecting? Wifi? USB? Direct? I had major issues with light staying green and I was having major connection issues with wifi. It's a long story but I was able to solve it. But from my experience. Three green lights with functioning laser curtains means connection issues

My limited experiences with Skytrak had one session where this happened a fair bit - ball placement laser wouldn't turn off, three green lights, no shot registration. Needed to be reconnected and the app restarted for it to resolve.

Thanks a lot for your help on this, bubbtubbs and scelebre!

I have tried to connect in each mode, network, direct and USB. It seems to work. However, when connecting in network or direct mode I always loose connection to the SkyTrak unit after I finish a session. I then have to turn the SkyTrak unit off and back on. Only then a connection is reestablished. In contrast, in USB mode I can finish a session, the connection stays alive and I can immediately start a new driving range session without turning the unit off and on inbetween. I found this behaviour a bit odd, but since the USB mode works without the need to turn the unit off and on and still does not register shots, I wasn't too worried about it.

It is definitely interesting to hear that all three LEDs stay green when there are connection issues. I was thinking that irrespective of a successful connection the top LED would turn red when a shot is registered. If this is not the case than indeed it seems a connection problem could be the reason for my problem.

Ok so I will fill you in more on the issue I had. I have a very strong mesh network in my house and all my devices run quickly with full bars in my garage. Skytrak would connect fine but not register any shots. After much troubleshooting I realized Skytrak was giving me a somewhat weak connection of only two bars despite being right next to my mesh router. But it did connect so I figured this was not the problem. After some additional time troubleshooting I noticed that if I brought Skytrak inside and turned it on next to my main router it showed full bars. For whatever reason it seemed like skytrak was not connecting to the hubs and only to the main. Long story short if I turn Skytrak on inside and connect and bring outside it works. If I turn it on outside it stays green and nothing happens.

Weird and probably not relevant to your situation but just goes to show how ridiculous this can be.

Thanks a lot for explaining in detail. I think this is quite relevant. It shows that connectivity issues lead to the symptom of three green lights, apparently being connected but no shots being registered. However, I experience my problem also in USB mode, which means it is unrelated to the Skytrak's wifi module.

Unfortunately, I currently have no clue, how to solve my problem. I have already reset the unit multiple times but this does not help. A complete factory reset might be an idea, but I have found no explanation on how to do this anywhere. Did not even find the firmware to download.

(Sorry for not answering in the comment section of the previous post, this was a mishap)

Unless the seller is bullshitting you on the fact it was working I think you have some sort of connectivity issue but who knows. Unfortunately this may need to be sent to skytrak to figure out. Does it read any shot at all?

Another funny story for you. Once I went into the garage and suddenly I was getting a ton of no reads. After much much troubleshooting I noticed a trend. On driver it would work 70 percent of the time. On short chips it would work 70 percent of the time. On all iron shots it would work 20 percent of the time. I am used to it reading 99 percent of the time. Turns out I was wearing grey shorts with a bit of a shine to them. Nothing crazy you wouldnt think anything of it but they had a sheen to it. Turns out they were causing reflection to skytrak. Driver worked ok because ball was up in stance and less shorts in the shot. Short chips same thing. Irons with the ball in the middle of stance did not read at all.

When I say no reads i mean the light did not turn red it just stayed as three green bars. I was completely perplexed. When I figured it out over the course of hours I literally ripped off my shorts and started hitting in my underwear and screamed in triumph.

Needless to say it is a finicky little machine. I absolutely love it and have had no issues for a long time now but there is definitely a learning curve to what works and what doesnt and what the potential issues could be.

I have a lot of sympathy for your story. You probably were quite relieved to notice that your Skytrak still works reliably! And it shows how tough troubleshooting of this unit can be.

The only issue I know of that can cause 3 green lights and no shot reads (besides burned out IR laser curtain bulb(s)) is having more than one app connected to the SkyTrak at one time - which can happen if you accidentally open the SkyTrak app twice, or have the TGC SkyTrak Interface app connected and try to use the SkyTrak app, or have an iPad with the SkyTrak app connected while trying to connect on the PC. So you've probably done this, but do a clean computer re-boot and make sure to only open the SkyTrak app when testing.

[ron burgundy]

Thanks, GungHoGolf, for your help! That is an interesting point. I just checked again and made sure that I am only connected with my laptop and the problem ist still there. So double-connections do not seem to be the issue in this case. But it also shows, that connectivity problems can cause the unit to constantly show three green LEDs while not registering shots.
