    摘要: A vehicle for seismic surveying fitted with a shock source device, and an electronic control and display device. The control and display device has a display panel which provides a display of required shock positions, and a movable display which moves along the display of impact positions in dependance upon vehicle travel to facilitate positioning of the vehicle at the required shock positions.
