New compact and fast three-component variometer measuring the total terrestrial magnetic field intensity in 20÷65 μT range and two transverse components in ±1 μT range is presented. The reproducibility of the field components measurements is 0.15 nT, the noise-limited sensitivity is 0.01 nT r.m.s. or 0.25" at 0.1 s sample rate.
