Body Fat % on Index S2 Smart Scale Seems Inaccurate

Jeff
over 3 years ago

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?

    Please add me to the list , my s2 scales are a major disappointment, with the fat percentage so high it throws out all of the metrics including fitness age etc

    Please add me to the case as well. I'd like to see the issue of body fat changing greatly just by adjusting age resolved.

    "add me to the list" lasts since Sep 20, 2021 and no solution
    I believe, it will end up like ascent/grade issue (since summer 2020) on all Edge **30 devices: Garmin will tell, the quote: "operating within our expectations"

    Any updates on this? 
    I bought the scale yesterday, shockingly off on body fat. My old $40 scale got the exact same reading as the gym professional scale of 24%. Garmin shows 27% last night. My weight is -1.2kg lower morning, body fat up to 29%. Just none sense. I bought the scale mainly to track body fat challenge for the new year. If it’s so bad, would have to return it. Very disappointed.

    I've simply added this metric to the ever-growing list of things Garmin's Marketing convinced me they computed without me researching if the calculation was useably accurate. So far, I think the watch gets my heart and respiration rates close to correct, and the Index S2 seems to get my weight approximately correct, and that's about it. Oh, and the watch tells time accurately too. The more esoteric the computed health/sport metric, the more skeptical I am that the value bears any relation to its scientific definition. I'm not even convinced the technology in the device - watch or scale - is even capable of gathering the needed information to credibly perform the calculations (e.g., can a sensor on the back of my wrist reliably detect the 'R' part of the heartbeat's PQRST phases, especially in a person with 'athlete's heart'?) Garmin's eco-system has definitely been an expensive case study in caveat emptor for me. I wanted to believe...

    I would return it if I could, they have known about it for over a year now since I bought mine, but have done nothing to resolve it.  My next scale will be anything but Garmin, which is too bad, because we have a bunch of the Garmin watches too so we were hoping it would all work together in harmony.

    Thank you for the advise! I will try until weekend, then to decide what to do with it...

    , I'm confused by this as well. I'm a fit cyclist (train 3-4 times a week) and my body fat % is 25! That can't be right...please keep me posted.

    .  Add me too please.  I'm 17% bodyfat according to a clinical grade inbody.   Really don't like my Garmin saying 27%

    Add me to the case as well.  Not only does body fat change on the scale when you change your age Conmect, but also your gender.  This scale does not do what it advertises and is very expensive for what it does do.
