ABSTRACT:
A procedure and a system for the detection of a plurality of passive electronic markers are disclosed. A marker location device capable of scanning for multiple types of electronic marker thereby increasing operator efficiency and reducing erroneous marker indications is described. In some embodiments, scanning may be performed at the operating technician's direction or may be performed in the background while the operating technician is performing other tasks.
