Abstract: The present invention provides the swimmer and or diver with protection against a shark. A probe held by the user can be deliberately armed before use. When armed the probe has protruding from its front end a dart. The dart is provided with a trigger restrained from operating by a trigger washer. When the dart is plunged into the shark's body it penetrates the skin and enters the body. The trigger washer no longer restrains the trigger which then allows a gas from a cartridge to enter the shark's body cavity. The gas bloats the shark's body causing the shark to rise in the water having lost the ability to maneuver.

More particularly, the present invention concerns a method and apparatus for recovering sunken wrecks wherein a harpoon is launched from a submarine device, implants itself in the wreck and is provided with a rope and means for fastening a pull cable. The end of the rope which is remote from the harpoon is floated to the surface. An apparatus placed at the end of the pull cable is caused to descend along the rope, and at the end of the stroke the apparatus automatically fastens itself to the harpoon. Thereupon, the wreck is pulled up by means of the pull cable.

Abstract: The invention is a gig for spearing fish. It has a handgrip with a bore, longer in its vertical axis than in its horizontal axis, running lengthwi,e through it. Slidably mounted in the bore is a spear shaft propelled by a loop formed of resilient tubing attached to the end of the spear shaft and also to the end of the handgrip. When the spear shaft is pushed backward into the handgrip, the kerf, which is cut around the spear shaft near the front end, engages a pin transversing the bore near the top of the bore so as to secure the spear shaft in a state of readiness. Pushing down on the front portion of the spear shaft, which is inclined upward in the bore of the handgrip, releases the kerf from the pin and allows the spear shaft to be propelled forward as the resilient tubing contracts.

Abstract: The fish spear includes a shaft with scissor-like blades on one end, the front edges of the blades defining barbs and the back edges being smooth. When the blades are in closed position, a spear shape is defined for spearing a fish. When the blades open past each other, the front edges with the barbs penetrate the flesh of the fish and retain the fish on the spear. A manually operable pull cable connected to the blades will move them to their closed position, thus retracting the barbs and permitting easy removal of the spear from the fish.

Abstract: The invention is a device for spearing fish and animals. It has a handgrip with a bore running lengthwise through it. Slidably mounted in the bore is a spear shaft propelled by a resilient band affixed to its end and to the handgrip. When a groove around the front portion of the spear shaft is moved back into the handgrip, a blade which moves inwardly in a slot extending from the outside of the handgrip through the wall of the bore snaps into the groove, locking the spear shaft in a state of readiness. The spear is fired by depressing a trigger which is attached to the locking blade and which moves the blade out of the groove.
