This patent describes an apparatus for introduction into a subterranean well on a first conduit insertable through a second conduit previously positioned within the well, the second conduit carrying thereon at least one auxiliary tool, each of the auxiliary tools having means movable in at least one of first and second directions for manipulating the respective auxiliary tool. It comprises: a cylindrical tubular housing, means for selectively indicating proximity of the apparatus relative to the one of the auxiliary tools when the first conduit is moved in a first direction; actuating means activatable by longitudinal manipulation of the first conduit and movable into engaging position with the auxiliary tool upon a first movement of the first movement of the first conduit in a second direction, thereby resisting movement of the apparatus in the second direction.
