A borescope includes a flexible cable having a signal carrier disposed throughout a length of the flexible cable. An imager head illuminates an object proximate to the imager head. An articulating member is disposed between the flexible cable and the imager head. The articulating member includes a spring having a coiled wire defining a central cavity, and an axially incompressible member positioned in a spring central cavity extending from a connector attached to an end of the flexible cable to the imager head. The incompressible member permits angular deflection of the imager head with respect to the flexible cable while precluding axial compression of the coiled wire and individual coil-to-coil contact.
