Does Shark Shield Technology harm sharks?

From the tests conducted to date, results show that Ocean Guardian's Shark Shield Technology does not harm the shark. The majority of testing on shark effect and health was carried out by a team of marine biologists at the KwaZulu-Natal Sharks Board of South Africa. 


Scientific tests show the field emitted by the device causes short term discomfort to the shark in the form of muscular spasms. However, once the shark leaves the area, there is no lasting detrimental effect to the shark.
