Nope, it's going to still be giving you yardage to the hole you're supposed to be playing. One advantage of a GPS over a range finder, range finder is line of sight(won't shoot through trees).
Well at some point you have to push some buttons to let the thing know what hole you are playing, right? I don't mind pushing buttons... I was just watching the Golflogix infomercial w/McCord last night and thought that if you never push any buttons it must just locate what hole you're standing on. Which one are you speaking of Eddie?
