Abstract: A device for clearing land mines. In a first embodiment, a buoyant air frame (11)supports a rigid plate (13) therebelow, the plate having a side wall adapted to cover a suspected area. The plate includes a pressure catalyst in the form of a shaped charge (44) or compressed air container which, when activated, causes intense enclosed pressure which destabilizes a buried mine (50) sufficient to detonate it without actuating a tripping device. In a second embodiment, a ground based maneuverable vehicle (111) supports a frame (112) which, in turn, supports a plate (113), the frame (112) including shock absorbing components (142-143).
