The security tag further includes a latching element disposed within the housing and positionable in a lock position and in an unlock position. The latching element includes a pivot axis. The latching element has a substantially balanced rotational response about the pivot axis when exposed to an external physical mechanical impulse. The security tag further includes a bias element that releasably positions the latching element in the lock position. The latching element releasably engages the inserted pin when in the lock position.
