Body Fat % on Index S2 Smart Scale Seems Inaccurate

My new scale seems to give me a wildly different reading than my old one. I was previously using a Weight Guru's scale which gave me a body fat percentage between 18 and 19 percent which seems reasonable given my overall weight and fitness level. The new Garmin scale shows me over 26% body fat. Both scales show identical weight so what gives with the wild body fat numbers? 

  • Which outright lie?  How have you, beyond a reasonable doubt, determined how it's being calculated and that their interpretation of the data is a lie?

    Being quick to espouse a legal course of action doesn't necessarily get you want you actually want, which is a scale that works and provides accurate metrics.

    Sometimes calm assessment rather then quick temper is better suited to certain situations.

  • This thread is now 9 months old. There were other threads, older than this one, about the same problem. How much time do you need Garmin?!

  • Nah, as someone said Garmin has no plans on fixing or acknowledging the issue. It's within their operating tolerance or whatever term they used.

  • My Garmin S2 scales are indicating a body fat % way too high (over 20% when it should be ~ 10%). Is there a fix for this?


    Moderator: there is already a sizeable thread on this, so moving your post here. Thanks for your contribution. 

  • 20% is a normal body fat percentage. Why do you think you should have 10%?

  • I just picked up the Index S2 and was shocked that a Garmin product could be this wildly inaccurate. I'm male, 40, athletic, and lean. Not writing a dating profile lol! I had to weigh myself a few times just to see if it needed a few readings. I'm in the 10-15% range and the scale says I'm 23.7% This is being an acceptable margin of error and I have a fragile ego.

    Based on the comments I'm seeing about how Garmin has not addressed this after several months of this issue being raised I may have to sadly return this and pick up another option that users have said are more accurate. Bummer.

  • 20% is a normal body fat percentage

    20% is only acceptable for an unfit person.

     25% is borderline obese.

    When Index S2 puts me in the 20-22% range I consider that insulting. My actual body fat percentage was 13% the last time I checked with a professional grade scale that costs $10k.

  • Took mine back to the store and got a refund , have ordered the withings ones instead, wanted to stick with garmin but can’t see the point in using something that is so inaccurate , using these scales skews all the body metrics in the connect app

  • Very disappointed from this scaler, a machine totally wrong number except the body weight, it’s been over one year and still same problem , every day need to watch wrong number , what a waste of money .
