I use an app called Fun Golf GPS, gives me very good hole information. With my series 0 it needed to be connected to the phone for location information, which meant the phone needed to be in a pocket otherwise if you walked around the distance information wouldn't change. I now have a series 2 with a built in GPS. When I first used it (again connected to the phone but the phone in the trolley) I found the distance didn't change. This is because, if the watch can get GPS data from the phone, it uses it in preference to it's own GPS (probably a battery saving thing). So now I start the app and once it is running turn on airplane mode on the phone. After this the app on the watch will use the watches built in GPS.
