This has nothing to do with scoring or left-handedness. I feel the greatest attribute of this device is informing you of the distance of your last shot. Any device can tell you distance to the hole only. One really can't use one effectively without the other. However, I find my watch missing the auto-detect more and more. While it was once 98%, I believe it is now only detecting about one-third of my shots during a round. Very frustrating. What can I do?
