I use a Bushnell laser ranger finder and a Bushnell GPS watch. I am about ready to ditch the GPS as on several holes that I play at my club, it is off more than 10 yards which is a full club difference. I like the convenience of a watch GPS but I would like to hear from others on what they use, good or bad. Using both is like a man who wears a belt and suspenders. He is a man that does not trust his pants.
