Sharks hunt with the help of very sensitive electroreceptors. The Sharkbanz magnetic shark repellant bands act like a bright light to their system and repels them. It goes on like a watch or anklet. The tech has been around for 10 years and has been extensively tested. They also have a chemical spray that also repels sharks.

Sharkbanz magnetic shark repellant

“Sharkbanz use special patented magnetic technology to deter sharks from attacking people. Most shark attacks occur in murky, shallow waters off the coast where there are a high number of swimmers and sharks sharing the same space. In this environment, sharks rely heavily on their electro-receptors instead of their eyes to “see” what’s around them. They possess the most sensitive electro-magnetic sense of all known animals, and use it to judge distance, shape, and even the heart rate of other animals near them. Most of the time, sharks get it right and leave people alone. Occasionally, they don’t. Sometimes when relying on their electro-receptors, a curious shark may bite a person in order to figure out what he or she is. These unprovoked “hit and run” attacks are the most common type, and Sharkbanz are an excellent defense against them. As the shark approaches a person wearing Sharkbanz, magnetic waves coming from the band disrupt its electro-receptors and it quickly turns away. The experience for the shark is, “like a person suddenly shining a very bright light in your eyes in a dark room, and its not pleasant”, according to Dr. Stroud. Once a shark comes near the band, it frequently leaves the area and does not return.”
