Underwater weapons range from the simple hand spear to guns capable of penetrating the largest fish. In the mid-1930s, Alec Kramarenko patented an underwater gun in which the spear was propelled by a compressed spring. Shortly after, there appeared a spring-propulsion-type gun invented by a Frenchman, Maxime Forlot, and the popular spear gun designed by his compatriot Georges Beuchat and propelled by a rubber elastic band. Other guns were designed that used gunpowder, carbon dioxide, or compressed air to propel the spear; one of the latter type, invented in 1956 by Juan Vilarrubis of Spain, became popular because of its accuracy, power, and simplicity of operation. Spearfishing guns often have a line attached to the shaft, making retrieval easier. gun propel
