Sharkbanz are a convenient and effective shark deterrent for the beachgoer, swimmer, and surfer. Sharks have the strongest electroreception (sensitivity to electrical fields) in the animal kingdom. Using patented magnetic technology researched and tested by marine biologists on predatory shark species, Sharkbanz overwhelm sharks' electroreceptors causing a highly unpleasant sensation that turns sharks away. Sharkbanz do not harm sharks or other sea creatures.
