post #91 of 91

I just got my opti shot. It seems to me that the lighting in the room where it is located is critical. I have noticed that my swing speed on the driver varies quite a bit. I have had a high of 109 MPH and a low of 75MPH. I have in the past had my club head speed clocked from 85 to 92 mph. I am wondering if it is the lighting effecting the sensors. Does anyone have any tips or contacts that can help me with this?
