The system requires that each hole has a tee shot on it, if the watch misses the recording of a tee shot the system will automatically add a tee shot in with a driver. This is because on the majority of tee shots it will be a driver that was played.
If you did not play a driver then you can change this in the editing/signing off process. Click here find out more about editing your round.
If you are continually getting this issue then there might be an issue with the watch. Click here to find out more about shot detection.
