InBody BWA 2.0 vs OMRON BF511
InBody BWA 2.0 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 BWA 2.0: when to consider it
The BWA 2.0 focuses on detailed body-water and composition results. Wrist and ankle clamps also allow bedside testing. Its results are especially useful where muscle changes need to be read alongside water changes.
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.

Fat-free mass is not pure muscle mass. A single result is not a diagnosis. Different devices and similarly named metrics may use definitions that are not interchangeable.
