Are there still PureLaunch users looking for a solution? Maybe there is one!

[Clubfitter73]

Good new first : I found a new way to calculate the ballspeed based
on the raw data from the PureLaunch!

Long story next :

Someone asked me some weeks ago if I could provide him with the
sofware that I wrote for the PureLaunch tests I did. The development
of that software was stopped around this time last year. It was
stopped because when trying to find the correct ballspeed (tested
with the Trackman) I thought that I needed to find the correct
LaunchAngle and the correct ballspin. I also thought however that in
order to find those two I needed the correct ballspeed. Catch 22...and
I stopped the development.

As I did want to help a fellow clubmaker I decided to locate the
sources of the software, compile it, test it en send it to him. During
testing seeing the bad ballspeed values the PureLaunch produces I did
not feel good about it and decided to once again spend some time
trying to find a calculation that works.

I still had around 83 shot in the database measured both with the
PureLaunch and the Trackman. Shots with ballspeeds between 60mph and
130 mph. Using my new calculation the average difference in measured
ball speed with the PureLaunch against the Trackman is 0.2mph with the
largest deviation being 4.3mph to fast and 2.4mph to slow. The
original Zelocity calculations for the same shots gave an average
difference of 13,7mph with the largest deviation 34,9mph to slow and
24.9 mph to fast.

Next ?

I will hookup the PureLaunch once again, hit some very high wedge
shots and low driver shots and anything in between and then re-checked
the new calculation. If its performance stays that good.......I will
release it to those that are interested.

If there are people interested I will then see if I can also solve
LaunchAngle....and if that is possible maybe the rest also.....

Can you help?

Yes, if you have an other LM I would love to receive some shots
measured both by your LM and PureLaunch to see if my new calculation
is not depending on just my setup.

Frans,

That sure is a lot of work! It appears you are moving right in on the
problems we experience. .Thank you.

I am not sure on how many original Users still have their monitors. I
was lucky enough to sell mine last summer for a great price. JW was
trying to market his as were a couple of others.

I hope some members will chime in here so they can get you some shots.

I have a PureLaunch and a GolfAcheiver I in my fitting studio.  I will do some side by side testing and get back to you.

Dale,

 

Thanks you! In order for me to check the data I need the data from the GolfAchiever and the raw.dat file from the zelocity for each shot.

Hi
I only have the Purelaunch so cannot help but look forward to your findings
as I do not use it much as I do not want to mislead clients with inaccurate
readings.

I'm glad the Purelaunch still has some life. Hopefully this will work
out. I would think that if there were someway to solve the software
issues that Zelocity would have done so. Good Luck...we need it.

I added some 73 shots. For some shots the speed could not be found.
all but one of those shots are wedge shots with ballspeed below/around
55mph

In a set of 144 shots my calculation had an average against the TM of
0.1 mph !!! largest deviation 6.5 high and -4.5 low. Zelocity
PureLaunch software average against the TM -16.8 mph, largest
deviation 24.9 mph high and 48.5 to low!!

[Jwally]

Sounds good Frans!

Yes, not too bad. I played a bit with the calculation, changing it's parameters and can even get better results but then for more shots the speed can not be found. So I think that currently the balance is correct.

 

Next : LaunchAngle

 

Dale, did you alread run some tests?

Launch Angle : measured 35 shots.

PureLaunch software: average 3.2 degree to high, largest deviations
-24.5 Degree to low, 11.6 Degree to high
My own calculations: average 1.6 degree to high, largest deviations
-3.0 Degree to low, 10.1 Degree to high

Launch Angle calculation is based on speed reading, it's sensible to
speed reading errors. If the error in the speed reading is 1 (one)
degree off then the launch angle calculation will change almost 3
(three) degrees!

Should read :

If the error in the speed reading is 1 (one) mph off then the launch

Have you guys ever heard of syntax?

Yes, currently using pascal syntax to program :->

 

Did you already find some time to test the PL together with the Achiever? Would love to receive that data.

[Dale Moser]

I have a Golf Acheiver I - no workee for lefties.  I'm a leftie.  I've got a guy coming by to hit some test shots for me.  Its winter here.  Guys are bowling and watching basketball.

I am looking at a Golf Acheiver myself. Not to excited about one but I
need something better than this to get Ball Speed and Launch Angle. I
have talked to them several times and at least they are responsive and
friendly! My P3 Pro Swing does a good job at club head path but no go
on the ball parameters at all.

There is no way I can justify the cost of a Flight Scope or TrackMan.

Dale how far away from the ball is the arm that sticks up? I had a
Vector Pro at one time and it seemed fairly accurate but folks hated
they unit sitting there. I could tell it was affecting their swing
some. It was a good unit except for that.

I just saw that AccuSport has signed an agreement with P3 to integrate their two systems and will have it up and running at the show.  FWIW

The arm is 12" from the tee.  I have never had a player say that it bothered them.

I will probably be buying a FlightScope at the PGA show next week, so I may well be selling the GA soon.

Thanks for the info .....

I would want the GA II if I bought one. That would at least give me
something for indoor use and if Frans gets the software going it would
give me an outdoor unit.

Why not use the PureLaunch indoor? If the calculations are done
correctly the ball speed is reliable enough

[Dale Moser]

The pure launch can be used indoors, and I do for lefties since the GA I is rightie only.  I prefer the GA I graphics, particularly the swing path and face angle displays.  Those are important displays

Improved calculation LaunchAngle : average 0,1 too high, largest
deviation 7.5 degrees too low, 4.8 degree too high. Results from 62
shots.

[Dale Moser]

I sold my Pure Launch on eBay today.
