Polar G3 GPS
on November 23, 2009
I was a bit concerned about this item when I read the problems that some people had experienced using this accessory. Problems with battery voltage and turning off after a short time. I ran a 6 mile run with it and there was no record of the run when I returned. The documentation gave the impression that the GPS unit would be already matched to my RS800cx Polar watch. I went through the matching procedure again and ran 7 miles through Boston Common and along the Charles River (on vacation). This time the the .gpx file opened in Google Earth and showed the whole run accurately covering the path that I had taken. I have used the same AA battery for the 3 runs used to date with no problems.
