An apparatus for indicating the orientation of a structure which includes an orienting sub releasably connected at an outer case. The orienting sub is at a preselected orientation relative to the structure. A change in fluid pressure of a predetermined magnitude of flow rate through the orienting sub will indicate that the structure is at a desired orientation in the well.
