Used the Neo Ghost yesterday for the first time. Didn't really save me any strokes that I could tell, but was playing on a well marked course and was impressed to see that it agreed almost perfectly with the course markers to middle of the green yardage. Unfortunately, I was a coward on green side shots, hitting tentatively and bleeding shots all around the green. The Neo did help a lot on one partial shot, letting me know I was 47 yards out, I hit a 3/4 lob wedge and was rewarded with a 10 foot putt for par that I missed. I was impressed that I only played 9, and it was the back 9, but the Neo picked that up without me doing anything to adjust the starting hole. Didn't expect that. Tonight, I'll play the poorly marked 9 hole muni. Hoping it really works on that one where I know it will help considerably to actually know the yardages. I have my doubts that this course will have accurate data associated, but hope to find out.
