The paper analyzes the problems, facilities and techniques for enhancing the accuracy of localization of a foreign ferromagnetic body. To tackle this problem is associated with further improvement of the parameters and characteristics of an electronic polarity detector unit, by using a new element base. In this connection, a PF-02 polarity detector model with its new construction of a ferroprobe transducer is presented.

To eliminate the ferroprobe transducer-inherent disadvantages, a whirl-current inductance transducer has been developed. The transducer localizes a foreign nonferromagnetic and ferromagnetic body in its borderline localization in the eye and in the whole body.
