Abstract
This invention relates to fishing tools for first determining the orientation of an object before retrieving said object from a well, well bore, casing, and the like. It comprises a base with a plurality of electrode welding tips retractably attached thereto and displaced in pre-selected pattern. Signals are generated as the electrode tips come into contact with the object indicating the orientation of the object. Electrical welding current is then selectively applied to a desired electrode to attach to the object for retrieval.
