Abstract
A device for locating a ferromagnetic object has a non-magnetic housing with a front end, a rear end, and a perimeter wall defining a chamber within the housing. A ferromagnetic member is housed within the chamber in a substantially fixed position. A magnet element is housed within the chamber between the front end and the ferromagnetic member, wherein the magnet element is reversibly movable between a first position in which the magnet element is proximate the ferromagnetic member, and a second position in which the magnet element is proximate the front end.
