The following steps are for calibrating the TruFlight 2 Club Camera. You will need to have your TruFlight 2 Utility updated to at least version 1.2.6.0 which can be downloaded under the TruFlight 2 section in this link: https://trugolf.com/trugolf-customer-support/
Step 1: Make sure there is no golf ball seen in the Club Camera window (boxed in Green) and click on the Focus/GS button (boxed in Magenta) below the camera window and let this run for a few seconds and then click the Accept button below and to the right (boxed in Purple).
Step 2. With the Club Camera window still clear of a golf ball, click on the Focus/GS button again and then place a ball in the center of the window (an arrow points to the center of the window in the picture). Let this run for a few seconds and then click the Accept button more directly below (boxed in Yellow).
At that point you should see the ball snap down into the position that the ball in the picture is and see that the ball is detected in the utility, then Save the changes by click on the Save Changes button circled in Red.
