Shots always going left... Any suggestions?

[mambo1888]

Ive not had a great deal of time with `Skytrak yet but it seems very left bias. Now I have a couple of thoughts on this, one is that my space is so small which means im hitting close to the wall and maybe im possibly trying to aim at the centre of the screen which would actually be left to the Skytrak. The other thought was that I was hitting left subconsciously trying to stay clear of the ST unit.

It feels as though I am well setup, square with the ST and shots that feel straight still go left. I looked at the marks on the screen and they all seem to be pretty straight ahead from where the ball is placed. Ive taken a couple of pics which show the majority of marks are on the right hand side of the screen which is straight ahead in my setup.

Ive checked levels and it seems to be ok. I have left the screen protector on as suggested in the box, not sure why they say to leave it on when it has a tab to take it off? I have the ST against the wall, does it need a certain amount of room at the back of the unit?

Try using the alignment mode and see if thats the problem.

You are talking about the launch direction being off, correct? Not the ball curving left? If it's launch direction, the best thing to do is get a laser level and shine it on the screen parallel to your skytrak unit. Hit shots and see if they are hitting right or left of the laser line and see if it matches up with your skytrak readings. If not, you might have to twist the unit a little until the results match up. I hear some units have to be adjusted a decent amount to get the proper launch direction. But keep in mind, skytrak shows a tolerance of +- 2°, so every shot will not be perfect.

I read a thread a while back explaining this in more detail. If I can find it I'll post the link.

Thanks for the info. Yeah its the launch direction that goes left not curving left. My garage is pretty Square and the ST is against the wall with the screen fixed to a joist adjacent tot he wall so I know they are pretty much bang on. I will admit that alignment can be an issue IRL but I do tend to hit straight. I can see the marks on my screen are very much on the right hand side of the screen which is directly in front of the ball so I feel they are going straight but end up way left.

I'm experiencing the same but I have a gc2. Small sim space like you, though. i think I will get a laser level to at least take one unknown out of the equation

[mambo1888]

It could well be the confined space issue either aiming to the centre of the screen or trying to avoid the unit. I dont think thats what im doing though as the marks on the screen are pretty much direct in front of ball position.

I seen a video on youtube that shows the option in skytrak to offset the screen so Im going to try that the help my alignment. But that will only make a difference in the skytrak app not TGC unless they have a similar method.

Im on holiday for a week so wont be able to try, although im taking my net and ST with me so I will see how it compares when using outside.

Keep me updated with your progress if you find the cause.

Well, there are three possibilities (or a combination):

Problem 1. User swing error: Perhaps subconsciously pull the ball as described.
Problem 2. User alignment error: The skytrak is not aligned properly by the user.
Problem 3. Skytrak internal alignment error: The user aligns properly, but the skytrak camera is not aligned with the case.

Test 1: Mark off your screen/net with string, tape or laser, and perfectly aligning unit with mark using alignment rod or laser. If shots that hit the mark are read left, you can eliminate 1 & 2 above. Sounds as if this has been somewhat tested.

Test 2: Continue from above and manually tweak skytrak alignment until shots that hit your mark go straight (HLA of zero). If after this, the left bias is gone, you have proven that problem 3 is the culprit. From now on, you will need to be mindful that the edge of the case is not perfectly aligned. If you hit from the same space all the time, you can create a permanent solution by marking off skytrak placement with pen, tape etc on floor/mat, or perhaps building a jig of sorts. Personally, I planned to do this, but never got around to it. I just eyeball, then hit 30 yard "chips" at my mark, and tweak until I am happy. It usually takes less than a minute.

Thanks for the info and sound advice.

Im not completely ruling out user error just yet lol. |Im by no means very good or consistent but im going to go down to the driving range tomorrow and see what results are like.

[Morini]

LOL. The good news is that you don't have to be consistent or good to sort out where the problem lies. It might just take you a few extra shots to hit the mark. It is always fun to hit outside and compare, but in terms of sorting this out, you are better off at home.

[mambo1888]

Haha yeah I might need a few attempts, but im sure I can get enough straight to start getting to the bottom of the issue. The good thing about the range is I wont have the same constraints with space and I will see the full ball flight. Like you say the issue could be the confined space messing with the mind when playing indoors.

[mambo1888]

Went out to the driving range today and weirdly shots were going left but showed pretty straight on the skytrak app. To be fair there was very windy so not the best day for testing. Much better readings though using real balls and having the space to swing freely. I think my alignment has been slightly left as well. Will try with laser when I get back home to the garage setup.

I realize photos can be misleading based on our perception, but it looks like you're hitting left of the alignment line. I would assume your ST red dot is roughly around the dark spot on the mat. If you line up both dark spots, it looks like a straight line would be just about along the right side of your impact screen. Hopefully I am wrong. By the way, nice set up!

Thanks Paul, sorry i must have missed your post the other day. Il check out the link when I get home.

Cheers mate, its a work in progress and just used what I had lying around (Old projector screen and black velvet material form a failed cinema project) Ive just ordered a proper impact screen as the screen thats up has a lot of bounce and Ive made a platform for the hitting matt that has sponge under the hitting surface as I was killing my wrists and arms with fat shots (yet to try this out properly)

You could be right I might be slightly left of centre but the ST was showing very very left. again the short distance makes it hard to tell how far left im hitting. Im going to set the net and hitting matt up tomorrow and have a go outside again.

I am thinking it is more to do with me than the skytrak though lol.
