Abstract
A detector equipped with force feedback for detecting detonatable devices such as land mines is disclosed. The detector includes a rod having a tip for placing beneath the surface of the ground and for contacting unknown objects. The tip ultrasonically provides an indication of the presence of a metal or plastic material. Means for providing a plurality of ultrasonic signals, each signal of a different frequency, to the unknown object via a single rod is used to compensate the device during use against unknown pressures applied to the rod beneath the surface of the ground.
