Sports Wallets Why Does My Nike Sport Kit Not Measure Distance?

Why does my nike sport kit not measure distance? - sports wallets

I bought my Nike kit yesterday and it gives me problems. The sensor can not find my iPod, is the signal. Time and voice calls and me. However, if I had of my career did not measure the distance at all. The sensor has been mounted in a pouch on my shoe laces - should work. Has anyone else this problem? Any tips?
