Eddy current probes for detecting defects in a ferromagnetic tube are disclosed. The probe uses partial magnetic saturation and includes two or more eddy current measuring coil assemblies in a probe housing. The coil assemblies are spaced apart from each other and located at positions of different magnetic saturation.
