Protee vs Flightscope......... Who do you trust????

[Boerdoc]

I am comparing the differences in analysis of the same shots taken by flightscope x2 and Protee. Please see the data in the attachments. Flightscope is 20 yards farther in carry distance!! When looking at the pictures please note that I am left-handed and the protee picture does not reflect that.

protee vs flightscope
Carry distance 117 vs 139
club path 6* vs 4.6* in to out
Launch angle 25 vs 24.5
spin rates 9334 vs 6220
club speed 73.33 vs 80.5
Ball speed 95.43 vs 100.5

The total distance will be off as I landed in the rough.

This is just my first analysis with one club and just 5 shots total. The trend was always that flightscope was 15 yards or so longer. I did not capture all the data for all shots. I just want to make meaningful conclusions to this. This was a crisply hit shot.

We are at 2300 elevation and I used medium for flightscope, about 3500 I believe. I will adjust this to low elevation. All my protee settings, like drag sliders are set to factory default.

I don't think Protee measures spin. This is likely why you have a difference.

As promised here are the adjustments I've made ball speed first and then drag;

Driver .96, 1.0
3 Wood .98, 1.01
5 Wood .97, .96
4 Iron .97, .99
5 Iron .97, .98
6 iron .97. .99
7 Iron .97, .98
8 Iron .96, .95
9 Iron .95, .96
PW .95, .97
SW .92, .99
LW .92, 1.06

I know that Protee will tell you not to adjust ball speed but for me it is huge, it confirms my feel of how solid I've hit the shot, it is more important to me then carry which can be impacted by uphill or downhill and wind. For example a solid 4 iron for me is 128 mph of ball speed, I can tell instantly by feel if my strike is off and sure enough the Protee numbers always confirm it.

hope this helps.

Thank you for these. I will try them out tomorrow. Any ideas on why the spin #s are so different?

See my post above re spin...

Protee does not measure spin. They'll never be the same.

I guess they could be close, but not likely. Too many variables on quality of strike, type of ball, impact conditions....etc.

[Cklguy2013]

Exactly Protee doesn't measure spin, IMHO, I don't thing they have enough in their calculations though. When I get a chance I'll post some of my Trackman spin numbers versus Protee generated numbers.

Evidently there was a "small bug in the left-handed player code" that led to reverse spin numbers in certain situations. I had to update to 3.06H interface to fix this. Will test this out later tonight.
