Better play by using GPS instead of rangefinder
I have an inexpensive Phantom GPS. Gives me front, middle and back yardages...I also have a rangefinder. I have started using the GPS for approaches, instead of measuring to pin..if pin is front to middle I just try to gauge what will clear the front. If it's back, I add some....I still use the rangefinder for distance wedges, and for practicing distance wedges.
For some reason this seems to be working better for me than focusing on just distance to the pin. It's also helping me learn more about how far I'm flying the irons.. (not very far, evidently)
