does exactly what it needs to do. Measure the distance to the hole. No more, no less. Every now and then I had the problem that the flag be confused with trees in the background. With a little practice you get the quick control. Friends with whom I play have a Leupold device and often seem to have trouble ("he does not pack the distance", "he sees the flag is not" ...) where I just can measure the distance in seconds. Characterized that it can measure the distance to nothing other than use in competitions.
