Flightscope Xi+ / Xi Tour Short Indoor Mode

[danielrobertbush]

Hi Guys,

Can someone please tag the most technical member of this forum. For Trackman you can determine how they are measuring their spin and all the basic principals that they apply to determine axis of rotation etc, as it is readily available within their patent.

I'm trying to determine how Flightscope are determining their spin rate, specifically for simulator use (indoor mode). Additionally, does anyone here know the additional assumptions that they are using between indoor mode and short indoor mode. As technical as possible is greatly appreciated, or even links to patents that I haven't been able to find.

Background information, I have a golf simulator hire business in Perth, Australia, and currently use a GC2. I splashed out because the additional cost is worth it for the accuracy, ease of use and limited missed shots. As the business has been running, I've come to realise that the GC2s level of accuracy may exceed that necessary for the majority of my customer's requirements. What they value more is famous courses and ease of use. To achieve this, I'd really like a ball tracker that doesn't need to be moved when switching between left and right handers, whilst not increasing the footprint require excessively. I'd also like to be able to use E6 for their local nearest to pin and longest drive competitions on well known courses.

The only ball trackers I know that are portable and don't require any movement when switching between left and right handers are the Flightscope and Trackman, with the latter being too expensive.

Help appreciated. Thanks

Ok, I've found some background information from you great people over a Google search:

So from all this information, I think that we have determined the following information:
- Not related to this thread, but the way that these Doppler launch monitors are not having wind affect their spin axis calculations outside are by calculating it in the first 40 yards, before wind has time to have a considerable effect
- Total spin is measured by Flightscope using the silver dot placed on the ball in an indoor environment, and then spin axis is calculated by measured values such as club path, ball path, angle of attack and maybe something else?
- Flightscope at times may not accurately measure the spin indoors for low spin rates, often with driver, due to an insufficient number of rotations. I never gathered if this results in a complete missed shot or if it just gives bogus results??

Now the question still remains, however I feel that a combination of their calculations being too proprietary and the number of people actually knowing this level of detail being minimal, what changes are they making in their calculations when you make the switch from indoor mode to short indoor mode?

Where I am at the moment, I simply don't have sufficient internet strength to go Youtube searching. If we just take GC2 or GCQuad to be the baseline of accurate data, then comparisons with Flightscope models in different modes in an indoor and outdoor environment must be so simple. I'm hoping that such videos have been made.

If it is lining up with GC2 even in short indoor mode under numerous conditions, I probably wouldn't be too phased in not knowing exactly how they are doing it. I'd be a little frustrated, but life could go on.
