Currently using a S625x that is about 6%+, which is a bit of a pain
I did try to calibrate it on a track but got confused, ran 1600m, then when i stopped on the line the distance kept going up, wasn't sure if it was supposed to so stopped it, should i have left it to stop by itself ??
Just got my S625x and went down to local running track to callibrate which i did over 1600metres, then i ran 1500metres and it showed as 1400m went i stopped, unless i got my math wrong thats 93% accurate, is there anyway i can reset it so its factory default and try it again ???
