Anyone else have to align the unit to the right to get the alignment dots to line up?

I have noticed this as well and still believe the alignment lasers are off, too, on my unit. When I aim them at a flag on the range, including a green laser extension, and actually hit the flag, the unit showed the ball flight carry of 150 yards was 10 yards left of target, before the rollout. No wind and none programmed. This would severely affect the directional accuracy of the Challenges to the Pin target games with the bull's eye displayed.Originally posted by Tbernardmd View PostLast edited by TripAces; 04-09-2015, 01:39 AM. -
Let me see if I can track down how we QA those lasers. I know it's part of the process. So both of you are experiencing left bias?Comment

Add me in there that the unit seems to "look" like its aimed slightly to the right when the laser dost are aligned straight. Having said that, when I align it using the dots, it "seems" correct in that if the ball hits the net left or eight of target, I get a corresponding read from the unit. I go to the length of shining a laser through the 2 dots and to my target to ensure its aligned properly. Since I have not used the unit outdoors I cannot comment except that I did some trig a while ago that told me that lining it up by eye at a target 200 yards out is going to be a lot more tolerant (due to trying to line up parallel to the target line) than trying that same thing with a net a couple yards ahead. I would love to see an integrated laser pointing forward or a sight that could be used for alignment.Comment

I too find that the plastic body of the Skytrak is aimed slightly right of parallel when the laser dots are aimed down the target line. It's maybe only a degree or two - very slight.Comment

There probably is some tolerance errors in the laser alignment. What I find works the bests using 2 balls, one your to hit and one ahead to mark your targe line with the forward laser. you really need to make sure that the laser is in the exact same spot on both balls. Even off a bit will affct the alignment.Comment

So, thought I'd post some pics of what this looks like for me.
As I had to move my mat around, I followed Bubba's suggestion above and set up using two balls.
Hopefully, it's clear from the pics (especially the top view) just how much to the right the unit seems to point by eye.
BTW, I should say that once lined up by the lasers, the ball flight feels right to me, and my sense of where the ball has gone matches what is shown on screen, and what I see on the course, so, I'm happy that the laser alignment is accurate, just that it looks odd.Comment

Great apljb. It's critical that the laser hits the balls on the same point on each ball. Even off a bit could mean 2 degrees or more inaccuracy. Using the ground where the laser hits can lead to inaccuracy because of that broad reflection the lasers have when they spot the ground. Use 2 balls or any object where you can hit th exact same spot with the laser while aligning. It won't be perfect but I do think the error is within 1-2 degrees overall.Comment

Here is my laser misalignment.Attached FilesComment

Trip, I can't tell much from your pics. Dd you read my post above ( #6 in this thread)? Use 2 balls to align the lasers and Targetline. Laser must hit e same spot on both balls. Do that and see how it looks,Comment

If your Skytrak unit is tilted towards you will have to turn it right to get a correct reading on the HLA. The unit needs to be leveled and aligned in all 3 axis to work correctly. Correctly in this case would be that it shows errors in all directions and is not biased towards any of them.Comment

Hi TripAces,
If the Skytrak unit is perfectly aligned towards your target then the spec says you will get +/- 5.23y accuracy on a 150y shot. But that assumes unit is perfectly leveled.
If the unit is tilted back (e.g. away from you) it will add to that error showing a result further to the left. 150y sounds like potentially an 8 iron with a VLA of maybe 35 degrees.
The higher the VLA the larger the influence of the miss leveled unit. The error is random and can be way much worse than +/- 2 degrees, but it can also be spot on. So unless you have a target to validate like you did in this case you will never know.Comment

Possible this is just me, but if i leave alignment mode on, the skytrak doesnt register any shots. It'd be great if i could also hit balls when alignment mode is enabled.
Do others have this same issue? Is there a reason that the skytrak doesn't register shots while in this mode for a specific reason?Comment

Mine doesn't work with alignment mode on either. It would help if it did, I agree.Comment
