I bought a Polar S625X a while back, but at the time, I was debating whether to get that or the Forerunner 305. I decided to get the Polar as I think it’s a bit more reliable and once calibrated, is very accurate.

I never did any calibration, but I was satisfied with the accuracy out of the box.

Well, I bought my wife the Forerunner 205 for Christmas as she recently started running, and yes, I gave it to her early . I took it on one of my runs and wore it along with my S625X and I must say, it’s a nice device. I did find that the S625X was off a bit and I put in a callibration factor of 970 (0.97)

I’ve set her up with SportTracks which is much better than the software that ships with the Forerunner. I have to admit that it is nice seeing where you can run. I especially like the ability to move along the course and see the data for that instant in time.

I’m still a bit apprehensive about the GPS devices as I hear about so many issues with reception, but I guess in TX, it’s not a problem since we’re so flat and we also live out in the suburbs with no tall buildings around.

I may just end up getting the Forerunner 305 next year
