OMRON BF511 vs Tanita MC-780MA
OMRON BF511 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.
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 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.

| Specifications | OMRON BF511 | Tanita MC-780MA |
|---|---|---|
| Method | Bioelectrical impedance (BIA) | Multi-frequency BIA |
| Measurement frequencies | 50 kHz | Not verified |
| Electrodes | 8 hand-and-foot sensors | Not verified |
| Maximum weight | 150 kg | Not verified |
| Documented outputs | Weight, BMI, fat and skeletal-muscle percentage, visceral-fat level | Fat, muscle and fat-free mass, body water |

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.
