InBody 720 vs InBody 970S
InBody 720 and InBody 970S: compare documented specifications, features and limitations. Check the reports and explanation offered by the provider. More features alone do not establish better accuracy.
InBody 720: when to consider it
An older detailed analyzer for following body composition and water during nutrition or sports programmes. Research mode adds regional phase angles; your report’s scope depends on the location’s settings.
InBody 970S: when to consider it
For a comprehensive consultation when you want to follow water distribution and phase angles alongside fat and muscle. This newer 970 generation offers detailed outputs for clinical, nutrition, sports and research settings.
