InBody 770S vs OMRON BF300
InBody 770S and OMRON BF300: compare documented specifications, features and limitations. Check the reports and explanation offered by the provider. More features alone do not establish better accuracy.
InBody 770S: when to consider it
A newer generation for nutrition and clinical follow-up with a detailed water report. Useful for discussing fat and muscle changes in the context of water distribution and phase angle, including individual body regions.
OMRON BF300: when to consider it
BF300 is a handheld body-fat monitor using arm-to-arm BIA. A primary study describes a single 50 kHz frequency, four electrodes and standing measurement with arms extended. Its principal output is estimated body-fat percentage; it is distinct from the BF511 scale.
