Love my "Golf Buddy." Just push a button and the Golf Buddy tells me (using voice) the center of the green or hold the same button and it tells me front and back. I don't have to struggle looking at some display that I can't see anyway with my poor reading eyesight. I have a Bushnell laser rangefinder too but I typically just want to know where's the middle of the green is at. Occasionally I'll use both the golf buddy and rangefinder to verify if the pin is front, back, etc. Golf Buddy's are relatively inexpensive too, usually around $100. As far as blind shots go, the golf buddy may not be a lot of help for that, and a better GPS that has mapping will be a lot better for that, but I personally don't usually miss not having those sort of capabilities. On rare occasion I'll use my 18 Birdies phone app for course layout with GPS, but it's usually just too much trouble.
