A system for repelling sharks is disclosed. Magnets are connected to a rod along its length. If necessary, the rod may be extended. Additionally, one or more flotation devices may be connected to the rod to manipulate or adjust the buoyancy of the system, depending on the user's objective(s). The rod is connected to a fishing line once a fish is hooked and is in close proximity to the boat or other structure from which the fisherman is fishing. The weight of the rod and magnets cause the rod to slide down to the end of the fishing line, where the rod will come in contact with the hooked mouth of the fish. As the fish struggles during the fight, the rod creates a protective magnetic field around the fish to deter sharks from engaging the fish.

An apparatus that facilitates search and rescue, for example, in open water. The apparatus comprises a substrate with a particular geometry and a perimeter. The apparatus further comprises a cover positioned atop the substrate with the cover also having a particular geometry and perimeter, which correspond to the geometry and perimeter of the substrate. An air-tight seal seals the substrate perimeter to the cover perimeter and creates a sealed internal region. A breakable vessel holding an illuminable dye located in the sealed internal region, along with an activator that is also located in the sealed internal region. When the breakable vessel is broken, the illuminable dye reacts with the activator and illuminates the illuminable dye.

Some embodiments may be of spearfishing apparatus fitted with at least one magnet configured to repel sharks away from the spearfishing apparatus. The spearfishing apparatus may be one or more of: a spearfishing shaft, a spearfishing tip, and/or a spearfishing gun. Some embodiments may be of personal floatation devices (PFDs) fitted with at least one magnet configured to repel sharks away from the PFDs. Some PFDs may be fitted with a tethered drop-down magnetic apparatus to protect lower extremities of a wearer of such PFDs. Such magnets may be electromagnets powered by batteries in some embodiments.

A shark barrier that comprises an anchoring assembly having a pair of anchors (9) with a flexible connecting element (11) extending between the anchors. The shark barriers also includes multiple spaced apart buoyant resiliently flexible elongate members (15) that are secured at one end along a length of the connecting element of the anchoring assembly to operatively extend generally upwardly from the connecting element. The buoyant members comprise an elongate flexible spine (32) that extends through a series of tubular members (38).

The LED lights for a surfboard is a safety device. The LED lights for a surfboard is configured for use with a surfboard. The surfboard is a floating structure. The surfboard is a roughly disk shaped structure. The surfboard comprises a superior face and an inferior face. The LED lights for a surfboard illuminates when the LED lights for a surfboard is placed in water. The illumination of the LED lights for a surfboard discourages predators in the water from attacking the LED lights for a surfboard. The LED lights for a surfboard comprises a housing, an illumination circuit and the surfboard. The housing contains the illumination circuit. The housing mounts on the inferior face of the disk structure of the surfboard. The illumination circuit automatically illuminates when the LED lights for a surfboard is placed in water.

When the breakable vessel is broken, the activator reacts with the illuminable dyes and illuminates the illuminable dyes.

A shark-attack-prevention ocean wall device is provided. The device is comprised of a post and net system that can be anchored into an ocean floor and provides a vertical net barrier. The barrier can be erected around a specific area of an ocean or other body of water to provide a swimming area free of dangerous animals, such as but not limited to sharks.

Disclosed is an apparatus that is able to generate an image to deter a shark from attacking a watercraft (e.g. a surf-craft). Also disclosed are methods of manufacturing and retrofitting watercraft to include the apparatus that is able to generate an image to deter a shark from attacking the watercraft.
