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.

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.
