Body Fat % on Index S2 Smart Scale Seems Inaccurate part2

But today mine has given me again an impossible value. Way off by more than 5%. I dunno why yesterday it worked more or less well but today not.

Yea, it really doesn't seem like they adjusted the original algorithm at all. They just added to the algorithm with the ability to enter a body fat percentage from another scale/DEXA scan. For me there's absolutely no improvement. It's exactly the same as it was before. I don't quite understand how Garmin thinks adding a measurement from another scale makes sense. It's basically admitting other methods of measurement are better than the Garmin scale. 

After some days checking the values given by the scale after the update I can say that It still gives impossible values.

Now it's way off by a 5% a bit less than before but the worst thing is that if you change the age now it barely changes the BF% but it changes values in  Bone mass and Muscle mass.

If any1 in Garmin want to check, I post today results.

6:34a.m. Real Age 50.

BF17.8% Muscle 33.4kg Water 60% Bone 4.9

6.35a.m. Age set to 17.

BF17.4% Muscle 36.4 Water 60.3% Bone 5.9

So with similar BF and water I win 3kg of Muscle and 1 kg of Bone. Same weight.

Tanita data 6.38 a.m.

Same weight. BF12.3% Muscle 65.8kg Bone 3.5kg.

Nothing more to say. Bf adjusted last two days in Garmin Connect with tanita values.

Index2 bought in March 2021. A week after that posted here the comparison values.

Contacted Garmin. Nothing changed.

 Kevin contacted me in September after many posts here. 

Not fixed in Januany(almost February) 2023

I just bought the S2 Smart Scale a few days ago. Compared with my other scale, a Tanita, it consistently shows a body fat percentage that is about 5% higher. I have just updated to the latest software yesterday. This makes me very disappointed with the purchase as I don't think I have that much body fat. It means that the S2 is not accurate in this aspect.

Once I completed the update, my scale no longer provides the advanced metrics.  Any suggestions?

Is it enabled in Garmin Connect?

I did.

1. I just purchased and received my S2 Scale. My excitement was short lived after just the first use. The body fat reading was 22.3%. Based on other devices I have used my body fat is usually reading between 10-12%. Based on what I read in these forums I thought the new updates fixed this issue but apparently not. I purchased the scale specifically for this use and feel like I just wasted my money. I'm glad I'm not using this in my healthcare clinic!! Do I wait for this to be fixed which seems to be unlikely, or go through the hassle of returning it? What to do!?

Did you really read this and other forums about the Garmin S2? After > 2 years Garmin is very mysterious about how the scale works. Or better, does not work for most metrics. Weight is ok I suppose. So, no don't wait. Bring it back if you can't live with a BF% based on algorithms(what?) instead of real measurements. You could use an Excel to do this!
