I'm wondering about trackers.... I'm no speed demon, but I would like to be able to accurately track my distance. I'm running with my daughter, and have discovered that my android phone (with strava / runkeeper) is recording about 0.5 km less than my daughter tracks with her iphone over the same route. I've recalibrated the compass, and checked the route on a map, so hers is correct. Essentially I've decided that my phone has a rubbish GSP chip (or whatever they have..).
So... can anyone recommend a GPS tracker? Maybe a (cheapish) Garmin?
