FYI my unit was always reading ball flight going right. After reading another users post I checked the level of the floor where it was setting. It was off slightly. I shimmed the right side of the mat to get it dead level not front to back but side to side. The direction problem was corrected and it seem to help the launch some. I think Garmin needs to attach a bubble level to the top of the unit like Skytrac that way even on the range you can get it level.
