Magnetic device to discourage shark attack
With shark attacks constantly in the news now as we head into summer, a product designed to be an active shark deterrent may be worth considering.
Sharkbanz is a device worn around the wrist or ankle when in the sea, using powerful permanent magnets to create an effective shark deterrent that's always on and requires no batteries or charging.
When sharks approach Sharkbanz, they detect the device's strong electromagnetic field, which provides a sudden sensation that is thousands of times stronger than the signal produced by anything in a shark's normal food chain and turn away.
Report the product developers, Sharks have the strongest electroreception (sensitivity to electrical fields) in the animal kingdom. They use this unique capability to navigate at night, when in murky water, and to hunt. When encountered in the wild, the Sharkbanz field is exponentially greater than anything the animal will have experienced before and highly unpleasant. This tells the shark it is definitely not food.
Sharkbanz was developed by a US team and is now available widely. In early October, Sharkbanz signed on as the official safety partner of the 2018 Hurley BL Blast Off youth surfing event held on Sydney's northern beaches.
