I just purchased a R10 after doing some research. I got the software downloaded, indoor range setup and ready to try it! VERY DISAPPOINTED! I setup the device and indoor range just as advised (8 foot between ball and strike screen, 7 foot between R10 and ball). Set my clubs to their settings, stiff shaft, etc. Calibrated the R10 and went to the range. On the range it had my 6 iron going 90-110 yards, typically that is my 155-165 yard club. So I went into the settings as advised by others set elevation to 4000 ft, humidity at 70%, temp at 80F, same results. The space between the R10 and the ball is covered, their is no distracting things (refrig, concrete, metal, etc). I am very unhappy and beginning to think I should have bought the other models that were $100-200 more. Any thoughts or ideas?
