Does the Shark Shield harm sharks?
From the tests conducted to date, the Shark Shield does not harm the shark. The majority of initial testing was carried out by a team of marine biologists at the Natal Sharks Board of South Africa. Scientific tests, as well as observations, show the field emitted by the Shark Shield causes discomfort to the shark, which can eventually lead to muscular spasms. However once the shark leaves the area, there is no lasting detrimental effect to the shark.
