Baynative,
How can it ever be bad to know the actual distance to the target??
Regardless of whether or not they can make an accurate shot, I don't see how it is bad for players to know the actual distance to the target. Most players have a general idea how long they hit each club in their bag (if they don't, the range finder will help them sort that out too). So using a range finder at least allows them a better chance to pick the right club. The range finder allows them to make their windage and elevation guesstimates based on the correct yardage.
I play to an 18 or so now and I can tell you that my range finder has helped me make more accurate shots. Yes, I still miss the green due to poor swings. but I am closer to the flag than I would be if I were still guessing at the actual yardage to the target.
