The technician explained the process and gave me an opportunity to ask questions. He explained the factors he was observing that allowed me to better understand the results with the various shaft and heads I was using. It allowed me to be involved in the decision-making process. The Trackman gave me immediate feedback that allowed me to hone my technic. I thoroughly enjoyed the 4 hr. session. The clubs arrived in 10 days. I had a 16 handicap going into the session. I am still learning the distances for each club; however, I have shot from 81 to 83 with one exception (which was the first round on my home course.) PS After the session, I played 9-holes on a local course and shot 37 in a drizzling rain!
