Abstract: A hand-held tool for a diver has a hollow tube to vent pressurized gas from an interconnected source through an opening in the tube. The vented pressurized gas aerates material of a seabed, and an anchoring system disposed adjacent to the tube is effortlessly inserted in the aerated material by a single diver. The hand-held tool permits an improved method of inserting the anchoring system as compared to the time consuming, strenuous, and noisy hammering procedure that usually requires more than one diver to successfully embed an anchor in the seabed. Different sources of pressurized gas for aerating the material may include a portable gas cylinder, diver's air tank, or hose from a remote source, such as a compressor. Quick-change connectors can be used to quickly and easily connect and disconnect components to supply more gas or add different components that will help insert different anchoring systems.

Abstract: A sand spike system anchors a cable in an earthen substrate. A penetrator connected to the cable has folded petal-shaped sections of spring steel propelled into the earth by a propellant. Cables connected to opposite petal-shaped sections help arrest penetration and spread the folded petal-shaped sections outwardly to increase the resistance to tensile loads. Sand spike system may use a delay activated or an electrically initiated propellant to drive the penetrator into the earth instead of mechanical, hydraulic, or pneumatic force. This permits remote initiation of sand spikes from a safe distance on land or underwater. In addition, each sand spike creates far a greater surface area to entrain and use the earthen substrate and not friction to anchor, and, as a consequence, it safely bears greater tensile loads on the cable.
