The invention herein disclosed provides a 2D coil and a method of using the 2D wound EC sensor for reproducing the Eddy Current Testing (ECT) response of a prior art 3D orthogonal sensor. The resulting thin-film eddy current array of coils configured to be placed parallel and against the test surface, and a corresponding eddy current circuitry operable to excite and receive eddy current from the array of coils. The array of coils forming at least a first inspection channel and a second inspection channel. The eddy current circuitry is configured and operable in a way that the one of the first pair of driver coils is usable as one of the second pair of driver coils; and one of the first pair of receiver coils is useable as one the second pair of receiver coils.
