If it works, it's a good watch/distance meter. However, I've had a few instances where he was on the right hole but missed by 100 yards! It seems like the connection to the satellite is lost or something crazy is happening. I restarted the watch and encountered the same problem. So all you can do is reboot and move the satellite. My old Garmin S2 was basic but always top notch. In short, the S42 has great specs, but out of the 8-10 rounds I played I had the same problem about half the time. For the money I expected more from Garmin. I ended up having to go back, it was too unreliable.
