An impact monitoring apparatus for indicating and recording the magnitude of force imposed in a specific direction on a particular axis of interest comprising two parallel saw-tooth leaf springs mounted in cantilever fashion one above the other. The upper leaf spring supports at its free end a designated mass. Upon experiencing a force or shock along the axis of interest the free ends of the springs are deflected so that the saw-tooth portions thereof mechanically engage and lock into one another. Movement of the upper spring is amplified by the mass thereon. Engagement of the springs occurs along a length from the free end, the extent of engagement being proportional to the magnitude of the force experienced.
