When the Winchesters tried to find out Lilith's location, Bobby used a tracking spell. Bobby's method involved a device that swung like a pendulum. The contraption was placed above a map. Bobby said that as long as he had the name and the corresponding ritual, he would be able to find the target’s location, accurate to the very street. Bobby then recited in Latin, causing the pointer to move. Once completed, the pointer swung and held its position to the location of the target.
