Garmin Index S3 Smart Scale: What the Leak Actually Shows

A possible unboxing video from Garmin's main reviewer has surfaced, pointing to a new Index S3 smart scale. No official announcement yet, but the source is credible enough to take seriously.

The current Index S2 has been around since 2020 and tracks weight, BMI, body fat, skeletal muscle mass, bone mass, and body water. Solid basics, but the body composition accuracy has always been its soft spot compared to competitors like Withings Body Comp, which adds cardiovascular health metrics via pulse wave velocity.

For endurance athletes syncing everything into Garmin Connect, a refreshed scale matters. If the S3 improves bioelectrical impedance accuracy and adds metrics like visceral fat or vascular health scores, it closes a real gap. Whoop and Polar don't offer a scale ecosystem at all, so Garmin has a genuine advantage here if the hardware catches up to the promise.

No specs, no price, no release date confirmed. The leak is thin. Worth watching, not worth pre-ordering.
