The Falcon and GCHawk are ceiling-mounted launch monitors
that rely on camera calibration to accurately track balls (and clubs, if club
mode is enabled).
Recalibration may be required if:
The
device fails to lock or intermittently loses lock
Launch
or club data is missing or inconsistent
The
device was serviced, repositioned, or remounted
The
hitting area or turf surface has changed
Step 1: Delete Old Calibration Files
On
your PC, open File Explorer.
In
the address bar, type:
%AppData%
and
press Enter.
In
the Roaming folder, click the up arrow once
to go up one level.
Open LocalLow → ForesightSports → ForesightOverheadCalibration → GCHawkSetup.
Delete
all .json files in this folder (examples: WandSamples.json, config.json).
Empty
your Recycle Bin to complete the removal.
Step 2: Recalibrate with the Tool
Download
the latest
Overhead Calibration Tool from our support
site (Link:
Falcon or
GCHawk)
Launch
the tool and follow the on-screen prompts.
Before
starting calibration, make sure your hitting area is clear of
reflective objects and lighting is consistent.
Using
the calibration wand, move it through the requested
positions/motions within the hitting area as directed by
the tool. Keep the wand visible to the cameras and move at a steady pace.
Let
the tool run to completion and save the new calibration.
Restart
the device.
After
restart, test ball/club tracking to confirm lock and
accuracy are restored.

FAQs
Q: When should I recalibrate my overhead device?
After service, relocation, hitting-area changes, or if you notice frequent lock
loss or inaccurate readings.
Q: What happens if I don’t delete old calibration files
first?
The new calibration may not apply correctly, leading to inconsistent data.
Q: Does Falcon use a different tool than GCHawk?
No. Both devices use the same calibration process and tool.
Q: Can I recalibrate if I only moved my mat a few inches?
Yes. Even small placement changes can impact calibration.
