Garmin vs. Polar (Page 2)

brown_dog_us - 2008-04-28 12:42 PM I use the forerunner 305 and love it. I run from time to time with a buddy who has a polar. We always compare numbers and see which watch we think is more accurate. We've been running the same 10k loop for a few years now. Back when I had a forerunner 101 it was the polar that was more accurate everytime. The 101 had a different gps antenae that wasn't very good. Once I upgraded to the 305 the polar's flaws started to show. The 305 is very close to dead on for a 10k run while the polar jumps around by as much as .4 miles but generally it is about .2 miles off during the same loop. The course is fairly hilly and our guess has been that his stride is inconsistant through out the run. Does .2 miles matter? Not to us, but if you are into the finer details it is something to consider. btw, He does go to the track and adjust his settings for the footpod regularly.
