Abstract: A device for locating a position of impact of a projectile upon a planar surface of a target. The device includes a plurality of lamina-type parallel planes, fully covering the surface of the target. Each plane has at least two windings, disposed on its surface, which are arranged in zones forming a continuous conducting path. When a projectile breaks a winding, its location is rapidly sensed and reported. The pattern of wires and layers provides simple, direct compatibility of the output of the device with digital processing operations. An orthogonally situated second device locates the impact position in two dimensions and resolves possible errors in results due to the size of a projectile or a boundary hit. The device can also locate the impact of a second hit.
