Garmin Approach S2 Golf GPS Watch (NEW VERSION w/ 30,000+ Courses) | 60-Day Buy & Try Return Policy! (Black)
I got this as a gift.  I often golf at places where they do not have good course markings or GPS units on the carts.  This is very accurate on every course that I have used it on.  it is not as precise as a range finder but I think it is much handier.  I get many people asking me where I got it after they golf with me.  Great product.
