Title: Inaccurate when running on a track
Review: Overall, I like the Forerunner 201. The display is large enough and it monitors/calculates all the data I would want to keep track of in my training. I have yet to try the computer download of the data.I noticed that the accuracy is not very good when running on a track (400 m per lap). When mapping the run, the route is all over the place (while the laps should be plotted on top of each other). Upon looking it up in the manual, I found that the position error of the GPS signal is less than 15 m (contrary to less than 1 m as the sales rep who sold the unit to me at the 2004 NYC Marathon Exposition had told me). That of course explains why it is not really suitable for monitoring the training on a track.
Is the review positive or negative?
