InBody BWA 2.0S vs Tanita MC-780MA
InBody BWA 2.0S and Tanita MC-780MA: 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 2.0S: when to consider it
The newer BWA 2.0S combines detailed water results with composition and offers a shorter test than the original BWA. Testing can also take place while lying or seated. It is mainly intended for care where a professional follows water distribution and muscle quantity over time.
Tanita MC-780MA: when to consider it
MC-780MA is a multi-frequency segmental BIA analyser. The manufacturer catalogue lists fat, muscle and body-water estimates with regional results and SD-card storage. MA alone still does not distinguish the column-mounted P and separate S configurations.

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.
