ABSTRACT:
A portable apparatus used for geophysical exploration for buried objects h as mines, relics and minerals utilizing a means to represent the endpoints of the apparatus sweep and means responsive thereto to blank data received at these points, thereby eliminating erroneous signals likely to occur when the search head is in a tilted position. The end-point representation may be achieved by either a metronome-type signal generator or by an accelerometer.
