ABSTRACT:
A passive inductor and associated circuitry which enables a compact search oil to simulate the response characteristics of a service mine search coil having different electrical properties. Output from the passive inductor is amplified and modified to duplicate frequency response characteristics at ship frequency, magnetic sensitivity, and output impedance of a larger search coil. Provision is made for disengagement of magnetic surveillance by the inductor.
