Ever wanted to surf without the fear of sharks? While there was not much you could do before, Joel Centeio is hoping to change that with his special shark repelling device.

Wilson Vinano created the lightweight machine. He said it emits an electric pulse that repels sharks by affecting the gel in a shark’s nose.
