InBody BWA 2.0S vs Tanita BC-601
InBody BWA 2.0S and Tanita BC-601: 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 BC-601: when to consider it
BC-601 is a segmental scale for tracking fat and muscle mass in five body regions. Its display sits on a pull-up handle and results can be stored on an SD card. Weight capacity is 150 kg; consistent preparation and interpretation matter when comparing changes.

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.
