LX Pro videos

The LX Pro videos have been shot - including the new LX Pro Club Tracking! - with examples of game play drives, chipping and putts!

I'll need a day or so to edit, combine and sync the two camera videos though. Videos include Setup, Control Panel explanations and captured image analysis.

Many new features have been added to both the LX Pro software and hardware.

November 21 2014

LX Pro videos and LX Pro B mods

The first LX Pro videos (showing chipping and putting first) should be completed and online by this weekend. Works great!

During the process though, I noticed a problem with the B Mod units so there's couple of days delay before I can send these units out.

The issue - which only occurred very occasionally - caused the main flash LEDs to stay in an on state and that's not good as they'll burn out very quickly like that. Usually they are only on for a few milliseconds.

Turned out that I had forgotten to solder in a comparator feedback hysteresis resistor and that caused the comparator to occasionally oscillate when the reference voltage was close to the IR Sensor input voltage.

And that in turn caused the one-shot flash circuit to keep on firing the flash LEDs. In fact, the only reason the LEDs didn't burn out was that they drew so much power that the 5 amp power supply cut out.

Anyway, the problem is fixed but I have to dismantle all the LX Pro's that were scheduled to go out in order to just get that 1 cent resistor in.

November 20 2014

Due to the overwhelming number of orders we're now receiving for all the GSA Golf product range, we reluctantly have to announce that we are sold out now until Christmas.

If placing an order, please allow a 4 to 5 week lead time on your shipment.

November 17 2014

LX Pro videos

Starting this week:

LX Pro videos using two Sony cam video cameras - one focused on the LX Pro unit itself with ball and club and the other on the monitors showing game ball trajectories and captured camera images of every shot.

To start with, we'll be showing chips and putts - which, according to reports we're receiving, aren't being detected by our competitor products.

A probable reason for this would be they are using mics to trigger the cameras - which don't work for chips and putts - and/or are using just one camera - in contrast to the LX Pro which uses two cameras.

If the competitor product uses just one camera, then the position of the ball on the tee or hitting position on the mat would have to be precisely known before a shot was taken in order to detect any launch parameters with any degree of accuracy.

This position, however, wouldn't be possible using just a laser pointer to indicate to the user where to place the ball. There'd be no accuracy in doing just that as the laser could be pointing anywhere on the ball - i.e front, back or anywhere in between.

Anyway, producing the videos is going to be fun so stand by.

LX Pro club tracking

We're nearly finished now with both the LX Pro and the CTS Pro club tracking software.

The above images show the composite of frames 2 and 3. Color coded lines show club path, club face angles before and after impact to ball.

Users can choose between face angles before, at or after impact to ball.

November 6 2014

LX Pro club tracking

We're about 75 percent finished with the new LX Pro club tracking feature. Above, the first LX Pro club tracking image. Notice that the center of the dots are exactly detected.

In contrast to our overhead mounted CTS club tracking camera -that views the club looking directly down on to it at 90 degrees - the LX Pro views the club at around a 45 degree angle. This, however, does not cause a problem with calculating face angle, path and club speed.

CX lighting

CX systems are now supplied with both dual halogen track lighting as well as IR LED lighting.

November 4 2014

Black fleece wall covering

"Tis the season" for golf simulator installations it would seem but we're still getting a number of issues with installers not following our instructions correctly and not ensuring that the walls and flooring in the Valid FOV of the H and V cams are either dark and non reflective to begin with or are not covered in a non reflective dark material . The above left image is a typical screen shot sent back to us with the complaint from the user stating "it doesn't work!".

In order for the cameras to detect ball traces, there must a a good contrast between the ball trace and the background so an illuminated bright wall background - as in the above left image - certainly will not work.

To-date, we've been supplying a sample roll of black carpet with every CX camera system for the overhead Hcam and this seems to work very well. i.e. the user or installer actually uses it.

So to address the Vcam wall issue, we're now also supplying a 9 * 5 feet black fleece roll. Users can then hang this material in the are of the valid FOV of the camera if required. Customers can also purchase this black fleece for around $15.00 from any good fabric store like "jo-ann".

November 1 2014

LX Pro IR Beam / Mic combo triggers

Normally, the LX Pro will only be using the IR Beam to trigger the cameras, however, you can also use a combination of both IR Beam and Mic triggers if ambient lighting conditions are such (ie too light) that the IR beam sensor sensitivity can't be set high enough to capture fast shots. In this case - and because a fast full shot will produce a very distinct and load club to ball impact sound - the mic can be used as a back-up trigger. i.e. if the IR Beam trigger didn't detect the ball, then the mic will.

The microphone trigger can be switched on or off via the Control Panel's main screen.

October 30 2014

LX Pro ball position indicator

The ambient light indicator we were testing yesterday also serves as a great ball placement indicator.

If the ball on the tee or hitting position is in the FOV of the IR beam sensor, then a bright blue LED will light up. In this case either the unit should be moved slightly forward or the ball hitting position moved slight backward.

If the blue LED is permanently on and there is no ball on the tee or hitting position, then the ambient light is too bright and the sensor's sensitivity should be reduced until it just goes off.

October 29 2014

LX Pro updates

Tests today revealed that the IR beam trigger sensor would require more dynamic sensitivity range for varying ambient lighting conditions either outdoors or indoors.

A new improved trigger circuit (comparator op-amp) is thus being installed in all units together with a new ambient light LED indicator. Shipments of all new and B mod LX orders are thus slightly delayed until next week.

October 28 2014

LX Pro updates

We're fitting all new LX Pro,s - including all those sent in for the B mod - with new circuitry for the club tracking feature coming next month.

Requests for help and support for a competitor's product

see Business News to read more.

October 27 2014

LX Pro updates

All LX Pro's - including all those sent in for the B mod - are being fitted with a mount on the rear that attaches to the club tracking stand should the user wish to use the LX Pro in club tracking mode in the future.

Camera alignment is now factory set individually for every LX Pro so user camera alignment is no longer necessary.

October 26 2014

LX Pro putting

Coming later this year: LX Pro multiple image putting mode

There's a camera based putting launch monitor on the market that takes a series of images of a ball rolling after it has been struck with a putter.

I'm not quite sure what the point of this product is but whatever it is there's quite a few people prepared to spend a lot of money to get it.

I inquired what the cost of this product is and was told by the manufacturer - a whopping $10,000!

Since then I've been on their mailing list with links to all the buzz about this new "holy grail" of putting monitors and about all the top PGA players that are using it.

Other than seeing how the ball travels, speed and it's spin rate (top spin in this case) I've got no idea why anyone would spend $10,000 on a machine like this but just in case you know and want this as well, we'll do it too.

It's just a software update so will be added to the new free LX Pro "Modes of Play" later this year.

October 24 2014

New LX Pro modes coming next month:

Want super accurate club angle of attack?

Switch the LX Pro to Club AOA mode and apply a single tracking dot to the side end of the club to get precise and accurate club angle of attack

Want super accurate club lie angle?

Switch the LX Pro to Club Lie angle mode and apply tracking dots to the face of the club to get precise and accurate lie angles

These software updates - that should be available next month - are free of charge to all LX Pro users.

Thanks to Frank H. for pointing out these additional LX Pro and CTS Pro possibilities.

October 23 2014

Switching an LX Pro to Club Tracking mode.

The LX Pro has the exact same components and circuits as our CTS Pro camera club tracking system and thus can easily be switched to club tracking by mounting it on a stand so that it looks down on the club.

When the LX Pro is used in club tracking mode you can still play a complete round of simulated golf. All shots from 200 mph drives to 2 inch tap in putts are detected.

Infinitely more accurate then any optical sensor pads and mats, the LX Pro club tracking captures fades, draws, hooks and slices like no other system on the market.

LX Pro club tracking software will be available free of charge in November

October 21 2014

Launch monitor price wars? see Business News to read more.

October 18 2014



We are currently nearing development completion of the most precise and accurate club tracking system available on the market today.

Both the CTS Pro and CTS Pro FM feature dual cameras that capture freeze frames of the club before and at impact to the ball.

Precise digital and programmable timing between the frames ensure that club speed, face angle and club path acquire an accuracy never before seen. And - due to our open technology - it's all verifiable by the user.

Price of the CTS Pro and CTS Pro FM is expected to be around $2,799 and $1,999 respectively.

Production start in November

October 16 2014

LX random dot pattern recognition

Random dot pattern recognition coding for the LX Pro has reached the Beta test phase. This method is now included in today's version of the CP. Select "Random dots" in the CP's main window to use this.

The above composite test image of frames 2 and 3 show a ball with random dots placed all around the ball with 4 of these in the FOV of the cameras.

(Note: placing dots all around the ball saves the player from having to bend down and align the ball logo or line to the cameras in the LX).

The image on the right shows how the intersection of the dot perpendiculars is used to determine spin axis.

The images also show that the ball has rotated 82 degrees within the time window between the two frames which equates to a spin rate of 6764 rpm.

October 14 2014

LX Pro IR beam trigger instructions

The first of the LX Pro B's with either the IR trigger mat or the internal IR beam trigger have been shipped so I've updated the LX Installation instructions to include this.

October 13 2014

USB 2 cameras on USB 3 ports

Up until now we've been recommending that each GSA Golf camera be connected to separate USB buses on the PC to prevent image tearing. i.e. the first camera uses the USB bus on the motherboard and all additional cameras required a separate PCI USB card.

The image tearing problem was caused by cameras being triggered at the same time which resulted in too much data coming in on the USB bus and the USB FIFO buffers would overflow.

However, since the advent of USB 3 I haven't noticed any image tearing problems anymore with multiple cameras connected to the same USB bus. i.e. all connected to ports using the USB bus on the mother board.

A reason for this could be that as USB 3 is 10 times faster than USB 2, it can handle a larger volume of data coming in at the same time from USB 2 devices. USB 2 cameras won't be any faster on a USB 3 bus but it would seem there is no longer any need to add extra USB PCI cards if the PC features USB 3.

Portable Club Tracking System for the LX Pro

We've had a number of requests to add club tracking to the LX Pro so here it is. The CTS-FM - camera Club Tracking System Floor Mounted.

The system is essentially the same as our standard overhead CTS but without the zoom lens, Halogen lamp and hitting mat sensor.

The CTS-FM uses the new IR beam trigger built into the camera and built in IR LED lighting.

Like the standard overhead CTS, the CTS_FM can also be used as a stand alone system to play a complete round of golf on the simulator.

With a price tag of just $999 it should offer a viable alternative to those low cost optical sensor pads on the market.

October 12 2014

LX Pro IR beam trigger works outdoors too

We have an Australian customer who has a number of open but semi covered bays on a driving range that wants the LX Pro to detect chips and putts as well as full shots. Up until now, using the LX outdoors meant using the mic triggers that are not suitable for putts and chips so we did some outdoor tests today with the new IR beam triggers. To my surprise - and even in the bright Florida sun but in the shade - the IR beam trigger worked great so we have a good solution for our customer.

All LX's will thus now be shipped with the IR beam triggers instead of line scan cameras and trigger mats. Existing customers that have ordered the - free of charge - LX B mod will also get this update free of charge.

BTW: Occasionally we like to try out our competitors launch monitor products at the golf stores to see how they fair with detecting chips and putts.

To-date, we haven't found a single launch monitor - neither radar or camera based - that can do either. We're always being told things like:

"Yes, it can detect a putt and a chip but the system has to be setup for it". "Um, no, high lofted shots like that can't be detected" .

October 11 2014

LX Pro IR beam trigger

For those that don't wish to use our IR trigger mat for the LX (ie would prefer to use their own hitting mat) but still want the system to detect all shots including small tap in putts and chips

(which preclude the use of mic triggers), we're testing a new built-in IR beam trigger method. This is the same trigger sensor that is built into the trigger mat but with an extended range.

Initial tests are working great so we may be making this method standard and offer the trigger mat as an optional extra,

October 9 2014

LX Pro and LX Pro B mod revisions

A couple of small but important revisions to the LX Pro ( also included in the new B mod for current users) has been made.

These include:

1. Camera 2 (the camera above camera 1) is now tilted down a touch to insure that the ball at ground level is completely in the camera's FOV.

2. The trigger input used for external triggering (i.e. via a trigger mat instead of the mics) has been modified to interface with an overhead line scan camera.

This was done so that users that don't wish to use the new trigger mat can still detect smaller chip shots and putts using their own mats.

October 8 2014

CX Hcam camera panel casing revision

The larger more powerful 200 IR LED lamp for the CX series we're using now is too large to fit in the panel casing for the Hcam so we're using the same case for the Hcam and line scan camera as the Vcam.

New LED indicators for power and line scan trigger are integrated in both the panel and standard casings.

October 7 2014


It's been a really hectic week here at GSA Golf - mostly due to the new LX Pro trigger mat testing - but we're now shipping.

All updates in this new version of the GSA Control Panel concern LX Pro so no need to download it if you don't have one on these units.

September 30 2014

They're back!

Yes! Due to popular demand we've reintroduced our famous PX optical sensor series of hitting mats

LX random pattern detection and matching

Software coding of the new ball random pattern detection method is now completed. Initial tests are working great.

LX users can now apply dots to a ball with a permanent black ink marker in any order whatsoever as long as at least 3 dots are visible to the camera no matter how the ball is placed on the tee or hitting position.

Dots should be applied within the dimples on the ball in order prevent smudging the impact screen.

September 27 2014

LX random pattern detection and matching

Currently the LX detects either a line / ball logo or a dot triangle on the ball to measure ball spin and spin axis.

However, any random pattern spherically printed on the ball could be detected and matched within the two frames which would simplify ball marking and increase accuracy.

Putting the dots or marks all around the ball saves you from having to bend down to align the ball logo to the camera for every shot.

Coding for this new random pattern detection and matching method should be completed this weekend.

LX Trigger mat testing

Testing the new LX Trigger mat yesterday showed that all the issues with mic triggers are eliminated. ie hitting fat or mic sensitivity problems. All shots from full drives to 6 inch putts are now detected regardless of hitting fat or not. The above image was taken using the trigger mat and shows how consistent the frame timing now is. i.e. frame 1 to frame 2 is 1.5 ms and frame 2 to frame 3 is 2 ms.

All LX Pro's now come with the trigger mat instead of a line scan camera. Existing customers can have their unit modified for the mat and get a free mat and reflex sensor if exchanging for the line scan camera.

Note: The new default setting for camera 2 trigger time delay is now 2 milli seconds instead of 3 ms.

LX Infinity

The above shows the new camera orientation required for the LX Infinity. i.e. the camera is rotated 90 degrees so that high launch angle shots are captured. Coding for this project went faster than expected so can go live tomorrow.

September 16 2014

LX Infinity

A couple of small hurdles have to be overcome with the LX Infinity before we can start production.

1. The zoom lens won't focus correctly when the distance to the object is less than 7 feet. It's the same lens as we use on the Ccam club tracking camera but as this camera is mounted 9 or so feet overhead this issue hadn't arrived before. To counter this issue during the test phase, we just unscrewed the lens a couple of turns so the the lens was a touch further away from the camera sensor and then in focus. The lens like this thus loose so we have had to source lens shims in order to tighten things up again.

2. Zooming in on the ball to achieve a better level of detail resulted in a reduced FOV and consequently a reduced launch angle detection. i.e. balls with a launch angle greater than 35 degrees were no longer in the FOV. Due to a stroke of genius (on my part BTW - huh, hmm), we found we could increase the vertical FOV of the camera substantially simply by rotating the camera 90 degrees. The camera image is not square - it is oblong - and as we don't need the width anywhere near as much the height, this solved the problem. Problem now is, a number of rather complicated image processing routines have to be modified in order for them to function with the new orientation. Should be completed by the weekend though.

LX Reflex trigger

The new LX Reflex trigger boards arrived today. We built the first using new improved IR emitters and sensors. Works great. The board features two IR LED emitters and a sensor in the center. The LEDs and sensor have a small rubber tubing around them to prevent reflections from the hole in the mat which are hot glued into position. The electronics - comparator circuit and reference voltage - are on the LX main board.

September 14 2014

LX Infinity testing

Testing phase of the LX Infinity "Left and Right hand player combined" launch monitor is nearing completion now. Production should start within 10 days.

Line scan camera

Amendments and additional line scan setup information has been published today as a result of testing the new CX1

GSA Golf moving up in the world

Above is a screen shot of page 1 of a "Golf Simulators" Google search done today.

Being consistently in number 4 position - above a lot of really big names in this industry - is even more astounding for us when we consider we do zero SEO. i.e. absolutely nothing. While others are spending vast sums to get to this position on page one.

Note: The Buyer's guide is not a golf simulator manufacturer so is not included in the ranking.

The number one position is held by a high-end golf simulator manufacturer with - it would seem at least - vast marketing and SEO budgets at their disposal. They make great products but in our opinion are not really number one. That, in our opinion, belongs to a company that starts with "A" - can't mention any names of course- but they seem to be slipping a bit in their SEO even though they have the best products on the market. Assuming you can afford the price tag.

And then we have the two rivals in the low cost golf simulator pad market. These guys sell tens of thousands of their products a month - at least that is what I have been told by people in the know - so GSA Golf probably won't get anywhere near them but we're hard on their heels now with our latest product lines.

Guess we're doing something right it would seem.

September 12 2014

New CX1 ball path detection method

Even though the CX1 features only 1 camera - usually only used to detect launch angle and ball speed -

ball azimuth ie. Ball path/direction can also be detected by measuring the width of the trace and comparing it to the trace width of a straight shot.

i.e. the trace width will be greater if the ball is traveling towards the camera and smaller if traveling away from the camera.

Click on above image or here to read more about the CX1 ball path detection method


This feature is available as of today's version of the CP

September 11 2014

LX Infinity

We're carrying out the final tests on the LX Infinity at the moment. Test unit is in a carry case but production unit will be in panel casing as shown above right. Note that the LX Infinity is the same as the LX Pro but with zoom lenses and Xenon IR flash units instead of LEDs so that the unit can be placed up to 10 feet away from the player.

LX Surround

The LX Surround is actually just two LX Infinities together in a single elongated case. As such, the LX Surround's hardware is completed but there's still quite a lot of software to code which won't be complete until 2015. The LX Infinity can be converted to LX Surround.

System data not being saved


As of the Windows 8 version of the CP we've had a number of reports that CP system data is not being saved. Thanks to crap Windows 8, what used to work perfectly, now fails on some PCs. That's only on some PCs of course. On others it works. Apparently only the Gods at Microsoft know why this is so we've changed the data folder to C:\Users\Public - which, according to all those in the know - will always work. If you are experiencing such problems then use today's version of the CP. It will first check for existing files in "C:\Users\Public" and if found, will read them. If not, the usual CP data folder will be used to read (i.e. you won't loose any of your settings) but after that data will be written and read from the Users/Public folder.

BTW. It's taken months to make all the changes to the CP for the Windows 8 version so I'm looking forward to all the surprises Windows 9 has in store when it is released later this year. After all, we've got nothing better to do.

September 5 2014

LX Line scan camera replaced with trigger mat

We've decided to replace the line scan camera in the LX with a FiberBuilt fairway grass trigger mat as testing and user feedback is strongly indicating that too many shots are not being detected with the mic triggers when striking the ball fat. Especially with wedge shots when players like to get under the ball for higher launch angles, the player tends to hit the grass fibers before the ball which will result in the cameras being triggered too early and the ball speed is either too low or no speed has been detected at all.

As the Line scan camera was only being used for putting we feel there'd be more value with a trigger mat that is guaranteed to detect all shots and most customers will require some kind of hitting mat anyway.

The LX can still be used without the trigger mat if desired- i.e. just using the mic triggers - and the sensor can mounted in most other hitting mats if the customer prefers not to use the FiberBuilt mat.

Sensors are available free of charge to current LX owners and the complete trigger mat is available for parts cost price of $120 plus shipping.

LX Lite testing

Much testing done today with this product. Results will be published tomorrow.

Ball logos and markings

Tests are showing that the Srixon range ball with a line marking - the one we have been supplying with the LX - is not so suitable for measuring ball spin axis. For spin rate it's great, but the line is too long to capture spin axis as we need to see both ends of the line and one end of the line can too easily disappear from the FOV of the cameras.

For best results, we're now recommending balls similar to the "Pinnacle" or "Srixon" distance balls. These balls have a shorter logo and the number and other markings are red so are not seen by the gray scale cameras.

Here, a shot of the Srixon "Distance" ball with the LX showing the strong lettering being easily detected and the red ball number not visible.

LX-Lite vs LX Pro

I'm doing some comparison tests between the LX Lite and the LX Pro this week.

Results are published here: Lx Lite-vs-LX Pro

August 26 2014



Spin and spin axis image processing updated to work with only partial triangle patterns. i.e. if only part of the triangle dot pattern is visible.

Bug: The new factory defaults scaling factor was multiplied by 10. This ensured that no ball launches would occur as the calculated speed would always be over the max of 200 mph. Now fixed with this version.

LX-Pro plug & play

The only aspect of the LX Pro preventing it to be truly plug & play are the line scan and mic sensitivity dials on the back of the unit. i.e. if these aren't set correctly then shots will not be undetected.

I'll thus be replacing this dials with internal 10 turn trimmers in future that are factory preset and not user adjustable - at least not without a small fine screw driver inserted into a small hole.


The LX Pro features two mic triggers and a line scan camera trigger. The idea with the dual mics is that one is set with less sensitivity to only detect full to half shots and the other set with more sensitivity to detect chips. The line scan camera is basically only used to detect putts where the club to ball impact sound level is too low for the mics.

With the new 10 turn trimmers it is possible to set the sensitivity of the mics so high that even most putts (at least 50%) would also be detected. We could thus produce a version of the LX Pro without the line scan camera at a lower price. I'll be testing this version next week.

LX Pro kit - $1,899

Having spent most of the weekend working on simplifying production methods of the LX Pro and having successfully simplified the assembly to such a great extent, I've revamped the idea of an LX Pro kit for those on a tighter budget.

The kit will just require a number of holes to be drilled into the casing but - as all the circuit boards are all pre-assembled and tested - final assembly is just a matter of a few screws, cable connectors and lens focusing.

The LX Pro kit - which will be available in September - is priced at $1,799. A $1,200 saving on the normal price.

August 8 2014

LX Pro stand angle


Testing today revealed that it is possible that very low launch angle shots may not always be detected.

The reason for this is that the ball is not fully in the beam of the LED flashes when launch angles are below a few degrees and thus not illuminated sufficiently for the image processing to find the ball.

The simple fix for this is to tilt the LX Pro unit a couple of degrees further forward so that the IR light beam is pointing further down. At present the rubber feet at the back of the unit set the stand angle at nearly 90 degrees. Adding a couple of 3 mm or 1/8 inch pads to the underside of the rubber feet tilts the unit a couple of degrees further down and the problem is solved.

You can use thick rubber washers screwed into the LX's existing rubber feet to increase tilt.

LX Pro nearly plug and play

With the new factory setup settings in today's CP (V we're nearly to the point of plug and play for the LX Pro. The only thing remaining is the sensitivity settings of the line scan camera (used just for putting) and the microphone trigger.

I'll be making videos of the LX Pro in live action shortly - maybe this weekend - that show that all shots are detected from full drives to 6 inch putts.

LX Spin Dot balls

I've programmed the CP to recognize the above dot pattern on golf balls used with the LX launch monitors.

The two dots close together are 3/16 (5mm) apart and the other 3/8 (10 mm) at right angles to the middle dot apart.

If you would like to make your own spin dot balls that eliminates the requirement to bend down and align a line or logo marking on the ball to the camera every time you tee up, then we have a ball marking kit available.

LX Pro - Putting


When putting with the LX Pro it was noticed that the ball images were darker than with a normal shot and thus not always being detected. The ball images are darker because the ball is rolling low on the ground and not directly in the main beam of the IR LED flashes.

To compensate for this, a separate camera gain setting for putting has been added to the system. The default putting gain is 20 db.

To set, go to the camera window in the CP, press the "P" on the keyboard to go into putting mode and increase the gain to 20 db or as desired.

CP factory settings

If you now right click on the Defaults button in the camera windows, then hard coded factory settings will be applied to the various camera settings.

LX Infinity

The LX Infinity is also available in carry case format (image left) as well as wall mount casings (image right)

The carry case is a third larger than the LX Pro case (now 14 * 12 *4 inches) and the zoom lenses protrude but can be unscrewed for transport.

LX Pro to LX Infinity conversion kit

If you already have an LX Pro or purchase one and then later want to upgrade to the LX Infinity, then we'll have a conversion kit available soon.

The conversion kit can also be used to convert V and H cams to a LX Infinity.

LX Pro B mod

If you have purchased a GSA Golf LX Pro before June 2014, there is a free hardware modification available.

Go to LX Pro B Mod at the bottom of the ProX Installation page for details.


Switching a Bcam to a Ccam and vice versa

The Bcam ball spin camera can be switched to a Ccam club tracking camera and vice versa with a click of a button.

If you already have a Ccam and would like to try the Bcam, a conversion kit will be required as the Bcam uses a Xenon flash.

The kit includes a new casing with electronics, IR Xenon flash and power supply. The kit will be available in September and will cost around $300.


LX Pro II hold up

Unfortunately we've run in a rather fundamental problem with the LX Pro II that has forced development and production to be put on hold for the moment.

The problem being: in order to detect all shots from zero to 60 degrees for both left and right handed players, the camera lens has to have such a wide FOV that we can't achieve the level of detail required in the ball image to accurately measure ball spin axis. i.e the ball image is too small and we can't zoom in without losing a great deal of launch angle range.

As it's getting rather late in the year now and we have the new Bcam and LX Infinity to get into production, we've decide to place this development on hold until we have more time to deal with it.

After all, we want to be at the PGA Show in Orlando finally this year and the clock is ticking and I fear I'll be bogged down with this issue and won't make it.

New product development completed for Fall 2014 / Winter 2015

Hi all! Martin here.

I'm pleased to announce that all new major product development for the coming golf simulator season has been completed and we will be ready to go into production of all the new products as of this coming September.

The new products are the Bcam ball spin camera and the LX Infinity and LX Infinity Quad series ball spin launch monitors. LX Pro II has been put on ice for the moment as we don't think it will compete with the LX Infinity very easily.

Having worked nearly 10 years on all the product developments - effectively without a break - I'll be off for a small vacation as of the 13th of this month till the 23rd of August. I'll still be keeping in contact with any via email though.

Bcam - ball spin camera

The slow motion golf impact videos from the MMU Biomechanics department on YouTube (click above image) where used to confirm that the ball spin rotation within the first 5 to 7cm of flight is visible to the Bcam camera when mounted overhead and that this first part of the spin is consistent and can be used to calculate the spin rate in rpm.
