I know there are more threads about fat %. Still not the same problem in many cases. Hence my finding. I had the Garmin Index (1) for years. Great because I never could and never wanted to compare. I think trends are more important. Now I have the Garmin S2 Index. There are measurement differences. OK, but fat percentage in 1 week + 10.6%!? OMG !?! I have a marathon in 2 weeks. @Garmin, seriously now? What is wrong? Or is the S2 correct and the Index(1) incorrect? Reading the other threads, the measurements seem inaccurate. Are you working on it or is Garmin the Index S2 as it is? Please let me know.
If I need to reset something let me know but my family is also complaining and ask me to buy something else than a Garmin Smart Scale.
