Essentially made up of a stainless steel cylindrical body of tubular shape, the energizer has a front section that may be unscrewed (cartridge chamber), apt to contain an 8-bore blank cartridge, or industrial type (easily found in every gun shop). This cartridge chamber is without barrel, thus permitting the axial ejection of the energy wave, caused by the explosion of the cartridge, generating waves of type 'p' (longitudinal) and type 's' (transversal).
