So this guy shows up at my local golf club with one of these new range finders so I had to take a look. No one in my circle of friends had even contemplated buying one of these gadgets until he showed up, so here am I a couple of weeks later writing my Golf Guru review based upon the two holes I played with it, before the battery ran out because despite it’s 14 hour battery life this visiting twit forgot to charge the thing up the night before. I love the fact that you can store all your courses on it, and that it gives some very detailed information about the course you are playing. The GPS seemed pretty accurate from what I could tell. In fact the device was cool, and I am quite tempted to get one. Unfortunately the guy who had it was one of those really irritating show off types, and so when the it stopped working my friends and I had little chuckle to ourselves.
