The amount of detail was pretty remarkable. After three tests showing results that correlated with what we were seeing in his change in phisque, I bought the consumer version

it shows fewer parameters but I had him measure on this vs. the pro machine and the results were pretty close. Close enough that I believe it will help me track body fat, etc. with decent enough accuracy to see if diet and exercise changes are working. |
Interesting device. I agree that correlating with gold standards is a good way to understand how less-accurate measurements can be used as approximations. I have a non-smart scale that "measures" body fat using impedance. It is considerably higher than my DXA scan. I have used tape measurements over the years, and these are surprisingly close to the DXA scan.
Next time I see a hand held body fat impedance device, at a gym for example, I will give it a try. It has been a while since I used one.
There was a U.S. Navy body composition calculation that used 9 tape measurements plus weight and height to calculate composition. Now it seems the U.S. Navy is using a much reduced set of measurements. I can't find the old USN method. If anyone has a link to this it would be appreciated.
