<p>A device (10) for repelling selected aquatic creatures, such as sharks. The device consists of an electromagnetic field generator (21, 30) for generating an electromagnetic field (50) that repels sharks and is supported by a buoyant device (20). This provides a shark-free region about the device (10). Multiple devices can be connected together to form an array of repelling devices, thereby extending the shark-free region.</p> |
