The most metrics

Salter Body Insight

A pullout handle and eight electrodes help this affordable new scale track up to 58 health metrics.

Dual-frequency bioelectrical impedance analysis makes for more accurate measurements, and the data is all broken down in Salter's app. So if you skip leg day, it knows!
