InBody 770 vs OMRON BF511
InBody 770 and OMRON BF511: compare documented specifications, features and limitations. Check the reports and explanation offered by the provider. More features alone do not establish better accuracy.
InBody 770: when to consider it
For detailed nutrition or clinical consultations and training follow-up. Alongside fat and muscle, it provides a dedicated water report, water distribution and phase angles. Testing takes place standing up.
OMRON BF511: when to consider it
BF511 is a scale with eight sensors contacting hands and feet. It uses 50 kHz BIA to estimate body-fat percentage, skeletal-muscle percentage and visceral-fat level alongside weight and BMI. It provides a whole-body overview; separate limb results are not documented.
