Abstract
In preferred embodiments described herein, a transducer head is affixed to the lower end of a wireline borne scanner sub for rotation thereby. The transducer head includes a pair of transducers which may be adjusted radially inward or outward with respect to the head so that optimum standoff may be achieved without the need for numerous transducer heads of various sizes. In a described exemplary embodiment, the transducers are adjusted by means of an indexing system which permits fine control over the amount of adjustment for the transducers.
