A telescopic stick for on-stream inspection of an equipment structure is disclosed. The telescopic stick includes telescopic segments, two swivel segments with two swivel joints, a mounting head attached to the swivel segments, an ultrasonic transducer (UT) probe mounted on the mounting head via a spring, and an electromagnetic leg protruding from the mounting head and adjacent to the UT probe, where an extended length of the telescopic segments exceeds human reach to allow a user accessing an out-of-reach condition monitoring location (CML) on the equipment structure, where the electromagnetic leg, when energized, engages the UT probe against the spring onto a ferro-magnetic surface of the equipment structure at the out-of-reach CML, where the engaged UT probe generates an UT measurement representing a condition of the equipment structure at the out-of-reach CML.
