This target has a laminated structure of layered matrials. The first layer is an insulating foam which abuts the front face of a metallic foil front electrode. The front electrode has a thickness not exceeding 0.005 inches. Behind the front foil electrode is an intermediate insulating layer that electrically separates the front electrode from the rear electrode. This insulating layer should be thin enough to permit usage of the target with small caliber ammunition. The rear electrode is a substantially rigid metallic screen having a mesh not exceeding 50 mesh. Behind the rear electrode is an insulating layer having a thickness greater than that of the intermediate insulating layer.
