You pull a loop of string around your ring finger while touching an object. At any time for the duration, you can remove the string and end the spell to determine the location of the object as long as it is within 100 feet of you. You gain a brief image of the location if it is familiar to you, otherwise you discern its direction. 

This spell can't locate an object if any thickness of lead, even a thin sheet, blocks a direct path between you and the object. Your connection with the object fails if you cast the spell again.
