OMRON BF511 vs Tanita BC-545
OMRON BF511 and Tanita BC-545: compare documented specifications, features and limitations. Check the reports and explanation offered by the provider. More features alone do not establish better accuracy.
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.
Tanita BC-545: when to consider it
BC-545 InnerScan is a body-composition scale with personal-profile memory. Its manual describes fat and muscle-mass results and graphs for tracking change. This is the original BC-545; specifications from later BC-545N or BC-545F models are not transferred.

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.
