Generally speaking the term ‘shark repellent’ is synonymous with snake oil. But that may soon change as the Australian Navy has officially adopted and approved a device called The Shark Shield. Is weighs 13.5oz, fits in the palm of a hand and uses electronic impulses that are said to deter a sharks up to a range of 8 meters. A 6 foot antenna is attached to the device – you better just hope it doesn’t get stuck on the side of a ship wreck. Still skeptical? The Aussie Navy tested the device for 7 months and apparently it met all of their criteria.
The Shark Shield was developed by Paul de Gelde, an Australian Navy diver, who in 2009 lost his hand and leg from a shark attack.
