SCX Xenon flash control circuit board

completed and tested

Nice to get down to some nice hardware development for a change today

This circuit board controls 2 Xenon flash units for the SCX dual ball spin frames

The SCX right camera will send out a strobe signal for each frame. The first strobe fires flash 1, and then (via a flip flop circuit) fires flash 2.

September 16 3:45 pm


New 1: More dynamic carry factor control for wedges.

New 2: Improved SCX stereo table default values

Golf Simulator Manufacturer's Google Organic Ranking using the Keyword "Golf Simulators" on 9/14/2023

1. TrackMan
2. ForesightSports
4. Full Swing
5. TruGolf
6. GolfZone
7. GSA Golf
8. AboutGolf
9. HD Golf
10. OptiShot
11. Uneekor
12. X Golf

Surprisingly, other well known companies like Flight Scope or ProTee didn't even appear in my search in after 10 pages

The reason I did this ranking search is because I'm being constantly bombarded with (so called) SEO experts that want to sell me their SEO services for an arm and leg, promising great returns.

While GSA Golf is not number one, it isn't at the bottom of the list either, so I very much doubt that adding any additional SEO to my website is going to produce any better results.

Note that the search list only included real golf simulator manufactures organic ranking and not resellers or sponsored ads.

When it comes to increasing sales volume, one thing above all will effect this : Advertising - serious big time advertising costing serious money.

In contrast to the others, I don't have a multi-million dollar advertising budget on hand (like Full Swing that can afford to pay Tiger Woods millions to use his name and images) ,

so have to live with a smaller sales volume. Fine with me though.

BTW I have no doubt that the above listed companies can afford the very best and most expensive SEO services available in order to achieve such high Google organic rankings.

Whereas, GSA Golf achieves almost equally good ranking with next to zero SEO.

Fix 1: SCX Issue with ball centering in camera 2

New: More SCX Xenon updates

September 4 5:30 pm


New: Image Brightness control de-activated as this was causing too many issues. Replaced with Contrast setting only now with SCX users.

Fix 1: Possible issue when clicking the OK button in the overlay playback window causing the next window to be showed too small.

New: More SCX Xenon updates

September 2 1:00 pm


Fix 1: Issue when in zoom mode in camera panel

Fix 2: Possible issue when system is looking for ball when Contrast Setting > 0 - e.g. ball sometimes a ball is detected without a ball being there

New: SCX Xenon flash frame grab completed

September 1 7:00 pm

SCX Xenon development

Tests today showed spectacular clear images of the ball at high speed.

Even dimples can be clearly seen.

This will allow us to develop the next SCX derivative

VisTrak SCX Xenon DP

System measures ball spin and spin axis using Dimple Patterns instead of ball markings


The SCX Xenon DP uses a hi-resolution camera with a 25mm zoom lens to capture hi-res images of the spinning ball in flight

This camera captures clear images of the ball dimple patterns (hence the name "DP")

so that ball spin and spin axis cam be measured without the requirement to use markings on the ball

Expected release date: 2nd quarter 2024

Note: the regular SCX Xenon can be upgraded to DP specs for just $200


August 26 1:30 pm


New SCX calibration default settings.

Calibration tests today showed accurate results with the cameras mounted at 9ft high.

As all SCX systems are now using the same calibration table. there shouldn't be any further adjustments necessary.

Default adjustments are: Page 1 adjust : 0.4200, all other page height adjustments set to 0.3200. Global and Individual height adjusts set to 0.0

August 24 4:30 pm

GSA Golf's Google ranking moving up

Even above Uneekor today with the search phrase "Golf Simulators".

I'll be starting a Google Shopping campaign soon too.

August 23 1:30 pm


Various smaller updates.

Less obtrusive invalid shot sound.

August 20 2:30 pm


Color camera updates - New naming convention for color shot video files.

Color video files are now only a 3rd of the size then they were before

A number of smaller cosmetic updates.

Video shot video playback is automatically stopped when manually opening the video panel.

August 18 10:00 am


Fix: Only one putt being detected when in putting mode

August 17 1:15 pm


Fix 1: The second camera in SCX systems not always waiting for the ball on mat to be detected

This is a very important fix as if the ball is not detected in camera 2, then the system would have used the ball position from the previous shot. In this case, ball LA and speed would probably not be correct.

Fix 2: Pulsing ball placement Laser not switching off when ball on mat is detected.

August 16 2:00 pm


New 1: In order to achieve more consistency with the systems sent out to customers, all SCX systems now use just one single stereo disparity calibration table.

New 2: After a shot and the user goes into the camera panels, data from that last shot is still shown.

New 3: Max Chipping mode delay frames increased from 8 to 16.

New 4: New quick update installation.

Use the green button (or the button on the top left here) to just update the current version without having to download all the other files (i.e. images, DLLs, sounds etc)

Fix 1: Irrelevant error and warning messages being displayed

August 14 6:05 pm


New : Page height adjust for the stereo disparity table

In contrast to the Global Height adjust that affects all 150 table entries, the page height adjust only affects the 25 entries in the table's page

August 13 1:45 pm


New 1: An error message is now shown in both the CP's main panel and camera panel if the dark ball strike trigger pixel is brighter than the user defined floor GS level.

System is unplayable in this case as the ball will launch immediately after placing it on the mat.

August 12 4:15 pm


New 1: Update for SCXi users

Fix: Stereo right camera not always centering the ball correctly after the "Looking For Ball" process

This was a difficult one to find. Took me over 8 hours of debugging work to find this sporadic bug in fact.

It's an important fix though as without correct ball centering in both cameras, stereo disparity values won't be correct and thus ball vertical height, LA and speed will be off.

New 2:

The ball strike trigger pixel positions are now shown with orange cross hairs in camera 1.

It's important to know that the forward pixel (i.e. the pixel in front of the ball) must be darker than the "Floor GS" and that the

Trig Light pixel (i.e. the pixel in the center of the ball) be brighter than 150 GS (Gray Scale) otherwise a ball launch will immediately occur.

A ball strike is detected when either the dark pixel goes light (i.e. the ball flies or rolls over it) or when the Light pixel goes dark (i.e. because the ball is suddenly not there anymore).

If you find that a ball launch occurs immediately after placing the ball on the mat, ensure the dark GS pixel is shown darker that the Floor GS. If not, increase the Floor GS so that it is lighter than the dark pixel.

In the above example, the Trig Light pixel shows a GS of 183 (i.e. over 150) and the dark pixel GS is 10 (i.e. darker that the Floor GS of 104)

New 3:

Fix: Color cameras not showing color images correctly after cameras are started and user goes back into the Camera panel

August 10 3:45 pm

New easier to follow camera installation instructions

LX2 gets a laser ball placement guide as standard now

August 9 3:30 pm


New 1: Update for LX2i users

New 2: SCX incorrect scaling warning message made brighter

August 7 3:30 pm


New 1: After starting the cameras from the CP's main panel and then clicking on the Cameras tab, the current frame now shows the ball located with stereo Disparity and ball Height is set to 0.

New calibration instructions

1. Place a ball on the hitting mat and click the "Start/Stop Vistrak" button from the CP's main panel.

You should see that ball is located in both the Right and Left cams after a couple of seconds

2. Go to the "Cameras" panel

This will set the measured ball height to zero cm and disparity to zero

3. Place the ball on a dark non reflective object of a known height (anywhere from 4 to 20 cm high) and click the Soft Trigger button in both cameras 1 and 2.

You should now see a new ball height shown at the top of the screen.

In the above example, the ball was placed on a rubber stand 4.3 mm high.

If the ball height shown does not correspond to the actual height of the ball,

then the stereo "disparity to height" table has to be adjusted.

Go to the SCXi Installation page for further calibration instructions

August 6 1:30 pm

SCX Cased track lighting version

You now have the option of a cased track lighting version of the SCX

July 27 12:00 pm

New track light lens

Price $39 each

July 26 4:00 pm

New SCX lighting comparisons

To my surprise, these new lower wattage (10watt) LED track lights produce better and brighter images than the 20watt versions of the lights.

Camera exposure can now be set at just 100 micro seconds (or even less) so that motion blur is essentially eliminated.

July 26 12:55 pm


A couple of SCX shot videos were sent in recently that showed that the ball was not correctly centered in the image (caused by head or hands in the frames)

which resulted in incorrect ball path and LA measurements.

A ball center check is now made on SCX stereo systems to correct this.

July 25 4:40 pm


You can now designate multiple clubs as chipping mode clubs (usually just wedges)

In chipping mode, the camera's frame rate is slowed down to allow the ball to be detected outside the launch zone area with slower shots.

Note that if the ball has not been detected to exit the launch zone area, then the shot won't be recognized.

July 23 5:30 pm

GSA Golf LX2 vs Bushnell / FS GC3


While running tests on my new LX2 launch monitor this weekend, I noticed that accurate club face angle detection isn't easy to accomplish.

So I thought I'd do some basic Google research on how the competitors solve this issue. Especially the GC3 that states to measure club data with just one dot on the club.

Well guess what?

At least according to all the research I've done, the GC3 doesn't even capture club face angle!

Club face angle at impact to the ball is arguably the most important of all club data points but this is just left out with them.

I know from many that contact me about floor mounted launch monitors that captured club data is of paramount importance to them

but it would seem that most are not aware that the GC3 doesn't inform purchasers that the (in our opinion) most important club data point (i.e. club face angle) is not captured.

(at least as far as we can tell from their websites)

I find this rather misleading to say the least.

Another issue I'm having with other LM manufactures that require club markings to be applied to the front face of the club, is that what happens if the player strikes the ball with a closed club face?

In such a case, (and from all the tests I've done) the dots wouldn't even be visible to the side mounted cameras.

If you ask me - somethings fishy going on with the marketing claims of some of these launch monitor manufacturers.

BTW The LX2 captures and measures club face angle, path and speed

(using a white reflective strip applied to the top of the club)

and does this for less than half the price of its main competitors

(without any subscriptions) -

plus it functions with TGC, GSpro CG3D and E6 straight out of the box.

VisTrak LX2 is the world's first and only floor mounted launch monitor that features a true horizontal camera

To the best of my knowledge, all others offer only systems with vertically mounted cameras so they can't see the club face angle.

And, to the best of my knowledge, no other floor mounted launch monitor on the market offers dual shot video playback from both top and side view cameras.

July 21 3:00 pm


A couple of small bug and cosmetic fixes

July 20 5:00 pm

SCX lighting comparisons

Currently all cased SCX systems are being supplied with both IR LED and Track lights

While all track systems are being supplied with track lights only



1. Stereo LA adjust feature in the Camera panel for SCX users. LA updated result is immediately displayed.

Feature saves having to open the Stereo Calibration panel.

2. A couple of small bug fixes

July 15 4:50 pm

ProTee Launch Monitors

GSA Golf have now joined forces with ProTee to promote and distribute the new ProTee Launch Monitor series in the US.

Priced from $6,000, these ceiling mounted systems have a significant price advantage over its main competitors (namely Uneekor EYE XO and TruGolf's APOGEE)

while matching (or even exceeding) features and performance.

Not least of which is the ability to measure ball spin and club data without the requirement to use special ball and club markings.

To the best of our knowledge, only the TruGolf APOGEE (priced at $11,500) can do this.

July 11 2:50 pm

Fix : Occasional incorrect ball speed frame count resulting in low ball speeds

May 19 4:52 pm


New 1: Faster shot calculations to reduce the ball strike to launch lag time.

Previous versions where running 2 pass data calculation routines which resulted in all calculations being run twice.

This version uses a single pass data calculation routine.

New 2: shot video playback overlay position out of bounds check

New LED track lighting test results

I'm pleased to say that the tests using the new zoom-able 4 10w LED track lights showed excellent results.

All new systems will thus be supplied with this new LED light track from now on instead of Halogen light tracks.

4 hi-power LED zoom-able track light system with 800 Lumens per light

May 11 11:30 am


Fix: issue causing ball strike frame not to be detected correctly that resulted in incorrect launch data.

New: Number of smaller improvements

May 7 1:15 pm

IR LED vs Halogen lights

Ball images using 3 24 IR LED lights

Ball images using 2 24 IR LED lights

Ball images using 1 24 IR LED light

Ball images using 2 50w 12 degree spot halogen lights

As can be seen, just 2 50 watt halogen lights easily out perform the 24 IR LED lights - even without having to increase the contrast settings

May 6 1:30 pm


Video frames

This major CP update reduces the ball strike to ball launch lag time.

Currently, the system is capturing 32 frames per shot, whereby only a fraction of these frames are actually being used.

Most shots only capture a max of 4 to 8 frames before club impact to the ball and another 4 to 8 frames after that.

The current longer lag time is due to the system looking for a ball that has long past the FOV of the camera. i.e. the system is looking for a ball that is not there.

Reducing the total frame count from 32 frames per shot (i.e. 16 frames before impact and another 16 frames after ball impact )

to 16 or 12 frames per shot ( i.e. 8 or 6 frames before impact and 8 or 6 frames after impact) should significantly reduce the ball strike to launch lag time.

Select the number of ball / club frames the system should capture for a shot in the Setup window.

Color cameras

The new color camera software updates are nearing completion and should be ready sometime this weekend.

Business news

Application for the trade mark "VisTrak" has been successfully submitted to the US patent Office 3 weeks ago.

While the application has been officially approved by the USPTO, (and to the best of our knowledge no one else has applied for this trade mark name before us),

final trade mark approval won't be given for another 6 months or so.

One of the main reasons to apply for a trade mark license is because Amazon require this before named products can be advertised on their platform.

Amazon doesn't require that the trade mark to have actually been approved, they just want to see that it has been officially applied for and not rejected,

which usually means the name is still available and trade mark approval is likely.

May 1 4:50 pm

Color camera systems

All the work done recently on the monochrome camera systems has now to be applied to all the color camera systems.

This work should be completed within the next few days

SCX camera alignment via frame image rotation

The camera alignment image rotation software is now complete and the first Beta release of this feature is now ready.

Many other improvements also in this update including:

Improved ball detection and faster shot calculation speed.

Note that this update required a large number of modifications and additions, and deveopment took the best part of 10 days.

In case of issues, re-install the previous CP version V from April 23 2023

April 24 2:00 pm

SCX camera alignment via frame image rotation

SCX Camera alignment can now soon be obtained with the new frame image rotation feature.

Current CP versions only rotate the co-ordinates so the user doesn't see the actual rotation.

This feature is 99% complete and should be available tomorrow.

April 23 2:00 pm


Horizontal correction angle now shown with yellow line from ball launch position

SCX Horizontal tilt correction software completed

Setup instructions to correct camera tilt alignment

1. Place ball on the usual place on the hitting mat.

2. from the Control Panel's main window, click the "Start / Stop VisTrak" button so that the ball is detected on its launch position.

You should see that ball is located in both the Right and Left cams after a couple of seconds

3. Go to the "Cameras" panel and select camera 1 (the left camera) and click the "Soft Trigger" button to see the ball.

4 . Using a straight edge (or line laser) that is pointing straight ahead towards the center of the screen and lined up against the ball on the hitting position,

move the ball around 12 inches forward in a straight line.

5 .Click the "Soft Trigger" button again to grab a new frame of the ball in its new position.

Ideally you should see that the ball is still exactly on the center line and the "Alignment Correction Angle is 0".

6. If not, then click the "Set L Angle to ..." button in order to correct the mis-alignment.

7 . Do the same for camera 2 ( the right camera )

April 21 2:00 pm


A couple of small cosmetic errors corrected

SCX Vertical Launch Angle calculation

In order to measure accurate ball vertical launch angles (LA), it's imperative that the cameras are mounted square to the ground.

Any horizontal tilt will result in erroneous LA measurements.

In order to check for horizontal tilt, place any straight edge or pole on the hitting mat from the ball launch position, pointing (as near as possible) perfectly straight forward and

grab a new frame with the "Soft Trigger" button in the camera panel.

The above image shows that the straight edge pole is in line.

In this image, the pole appears tilted.

In order to correct the problem, you will find that there is no direct easy method to horizontally adjust the tilt as the low cost plastic mounts only feature vertical tilt and rotation.

One simple temporary solution for the moment is to place a small shim or piece of thick tape under one side of the mount base to correct the tilt.

Do this check and adjustment for both left and right cameras.

The more elegant solution is to correct the tilt mathematically with image rotation in the Control Panel's image processing software.

This "tilt correction" software should be available this coming week.

April 20 1:45 pm


Fix: Ball Strike frame not always being detected correctly

April 19 1:40 pm

www.golf-simulators.com now back online

Due to an administration error with the website hosting company, this web-site URL was down for the last 3 days.

Of course, everyone thought that GSA Golf was out of business during that time.

As you can see, the problem is now resolved though.

All other GSA Golf related URLs and web sites (i.e. www.gsagolf.com and www.vistrak.com) are also up and running as usual

as are the Google Adwords advertising campaign and the all important Google search ranking.


New hi-precision SCX calibration tables

The "disparity - to - height" tables are made by increasing the ball height in single 0.3 cm steps for a given camera mount height and camera separation distance

and entering the disparity value in the calibration table.

First table in this update is for an 8 ft mounting height and a camera separation distance of 20"

Second table in this update is for an 9 ft mounting height and a camera separation distance of 28"

To activate: go to the camera panel, select calibration mode and - depending on your camera mounting height and seperation width -

click either the new "Using 8ft x 20 inch" or "Using 9ft x 28 inch" table.

April 17 12:35 pm


Basic SCX Stereo camera calibration

Fix: Disparity shown in calibration panel not always correct.

Fix: ball path not calculated in calibration panel.

New recommendation: Min distance the stereo cameras should be apart is now 20 inches as any less is not producing sufficient disparity values to calculate LA accurately.
