Shark Shield Sales Boom - Australia

For one of the few technologies that actually work - when used correctly, we're not surprised by the news coming out of Australia this week. Nothing replaces common sense when dealing with sharks.

Sales of an Australian-made device to repel sharks are booming after three recent attacks in Sydney.

SeaChange Technology, the Adelaide company that produces the electronic "Shark Shield", says inquiries have tripled over the past two months and sales have increased by 50 per cent.

"We cannot keep up with production. Twice in the past two months we've increased our production line only to find immediately that we have to do it again," SeaChange Technology co-founder Paul Lunn said.

The device, which costs between $600 and $700 depending on the model, weighs 80 grams and can fit into the palm of a man's hand.It works by releasing electrical impulses that are painful to sharks within seven or eight metres.

"The shark is only affected while it's in the zone of the waveform of the unit. Once it gets out of that, there's no long-term damage at all," Mr Lunn said.Police dive squads in each Australian state have implemented a mandatory-use policy for the "Shark Shield" and NATO has accredited it for use by the military.

Editors Note: In response to increased use of Shark Shield technology by film and television companies, Shark Shield Pty Ltd has appointed Shark Divers as its official regulatory authority for the Northern Hemisphere.
