ELECTRICAL SHARK REPELLENT
In certain areas of the world, popular swimming and surfing beaches happen to be particularly prolific in the number of sharks that have made these areas their habitat. When this occurs, the incidence of attacks on people increases significantly. Also, there have been serious threats posed upon regular SCUBA divers (particularly commercial divers) by more aggressive shark species (generally considered to be Great Whites and Bull Sharks).
There have been serious efforts to keep sharks away from the areas in which human beings can commonly be found. These have included the killing of large numbers of ‘dangerous’ animals, shark nets, cages in which bathers are protected and more. However, these efforts invariably compromise either the shark or the bather. Shark nets kills thousands of animals every year as they become entangled in the net and drown under the weight of their own body as their buoyancy is compromised.
In response, scientists have been experimenting with the very intense electromagnetic response displayed by sharks. These animals are equipped with Ampullae of Lorenzini; sensory organs situated in the snout, which pick up even the minutest electrical charges. These are used during hunting, as all animals (including people) emit an electrical charge in the water. After years of tests and product development, items such as the SharkPOD (Protective Oceanic Device) and Shark Shield have been developed and used in different locations around the world. Both of these devices emit a three-dimensional electrical impulse around the diver or surfer bearing the device. This impulse is strong enough to cause spasms within the snout of the shark, an unpleasant sensation that deters the animal, driving it away from the vicinity. Because this is a temporary sensation, it inflicts no permanent harm to the animal, while it protects the diver from potential attacks. It also has no negative effect on the environment, unlike nets and other such measures. It does not even have an effect on other animals, including less sensitive shark species.
These devices are powered by batteries and become effective as soon as the wearer enters the water; i.e. it does not need to be deliberately activated. These devices are usually small plates that can be strapped onto the arm or leg of the person entering the water, and can be used while snorkelling, SCUBA diving, swimming, body boarding, long boarding, surfing, spear fishing, kayaking, fishing and so on.
