The SharkStopper PSR is worn on the ankle, and produces orca-like sounds
The PSR contains a sensor that automatically activates it when the wearer enters the water
As regular viewers of a certain TV channel will already know, the orca (or killer whale) is one of the only animals that kills sharks. It would follow, therefore, that sharks generally try to stay away from them. It was with this fact in mind that the SharkStopper Personal Shark Repellent (PSR) device was created. The ankle-worn gadget emulates orca vocalizations, and has reportedly been shown to repel various species of sharks.
