With the rise in shark attacks on surfers off the coast of Australia, local wavebreakers have started to integrate SurfSafe electronic shark repellents into their boards.
According to Reuters, the SurfSafe device costs $ 280. Its principle of action is based on the creation of an electronic force field that blocks the electroreceptors of sharks, also known as Lorenzini ampoules. These are special glands that respond to electric fields with a strength of 0, 001 μV / m and allow the predator to find prey.
There have been 12 shark attacks on humans in the Australian state of New South Wales this year. In 2013 and 2014, there were only three attacks each. In February, a great white shark killed one of the surfers. According to technical experts, the SurfSafe device does not guarantee one hundred percent safety for extremists, but it can make their life much easier. "The devices will not prevent a meeting with a shark, but will significantly reduce the chances of being bitten," - explained marine ecologist, McQuarrie University professor Rob Harcourt. Surfers themselves understand that a hi-tech novelty will not save them from fate, but claim that they are safer with it.
