Abstract
A preferred embodiment of the invention includes a passive type marker device (10) with a stem (11) placed in contact with or adjacent to a hidden object (14) or other particular point, providing for visual and/or electronic identification of such. Measurements (20) and directional markings (24) imprinted along the stem face indicate distance to the object. An alignment saddle (12) astride the object self aligns an arrow opening (18) through the stem defines the object'"'"'s orientation relative to its surroundings. The device'"'"'s color indicates object type such as red for electric, blue for water, etc. A marker dial (46) for optional placement in a finished surface also defines the object depth. The dial is indexedly installed atop an alignment indicating adapter (44) which is self aligned by insertion into the arrow opening of the stem. An arrow and indicia atop the adapter indicates the orientation and size of the object. An electronically locatable tuned circuit is encased within the alignment indicating adapter. Alternately the stem, the dial with the adapter or the adapter alone may be placed in the vicinity of the hidden object or particular point without the other parts.
