Shark POD

from Wikipedia, the free encyclopedia

Shark Pod ( P rotective O ceanic D evice ) is a device for warding off sharks. It builds up an electromagnetic field that the sharks perceive through their receptors under the skin and that irritates them. When they swim in such a field, they usually turn away because of the perception of the EM field.

effectiveness

The effectiveness of shark defense devices based on EM fields has been questioned several times , especially in Australia since the introduction of the Shark Shield products. In 2010, SafeWork SA , the competent authority in the south of Australia, carried out a study on the effectiveness of the Shark Shield Freedom 7 product . The results were published in June 2012; The result was that "Shark Shield Freedom 7 had an effect on the behavior of great white sharks, but did not deter or drive them away in all situations".
