Tanita MC-780MA vs Tanita RD-545HR
Tanita MC-780MA and Tanita RD-545HR: compare documented specifications, features and limitations. Check the reports and explanation offered by the provider. More features alone do not establish better accuracy.
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.
Tanita RD-545HR: when to consider it
RD-545HR uses dual-frequency segmental BIA with a handle and app connection. It provides fat, muscle and regional results as well as heart rate. HR distinguishes it from the original RD-545; a scale’s bone-mass estimate is distinct from bone densitometry.

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.
