When i was using it, it didn't interfere. I didn't use it a lot though, once i got ball tracking and knew it was giving me correct readings, i pretty much used the skytrak most of the time after. I just wanted to see how accurate the P3 and the optishot were compared to ball data from skytrak. P3 was more consistent than opti and their ball flight was closer to skytrak than opti as well.
