From the opening page of the user's manual. Users unintentionally being in close proximity, or in contact with the antenna, may possibly suffer muscle spasms in varying degrees; we recommend that users may need to make adjustments to limit contact in these situations.

All predatory sharks have highly sensitive electrical receptors called “Ampullae of Lorenzini” located in their snouts. These tiny gel filled sacs can only sense electrical current from prey at very close distances, typically much less than one meter. As sharks can only sense electrical currents at very short distance and all electrical currents are dispersed rapidly in water, the myth that sharks can sense electrical current at great distances is not true: as a result electronic shark deterrents do not attrack sharks.
The powerful but localised electrical field generated by Shark Shield devices causes the sharks gel filled sacs to spasm and the shark to flee the immediate area. There are no known long term adverse effects to the shark and as a result Shark Shield devices support the conservation of sharks by removing the need for culling or other lethal means of managing human and shark interactions. Shark Shield devices do not affect other ocean creatures.
