How it works

Shark Shield® Technology 

 

Sharks have short-range electrical receptors in their snouts called the “Ampullae of Lorenzini” used for finding food.

Ocean Guardian’s Shark Shield Technology has been developed to specifically take advantage of these highly sensitive receptors, creating a powerful three-dimensional electrical field which cause spasms turning the sharks away, including Great Whites. As fish are without these receptors, Shark Shield Technology has negligible effect on them.

Shark Shield® Technology

Shark Shield Technology consists of two electrodes, which when both are submerged, emit a three-dimensional electrical field surrounding the user or area. When a shark comes within a few metres, the field (emitted by the device) causes the shark to experience muscle spasms. This does NOT harm the shark in any way, merely producing a high level of discomfort.

Shark Shield Technology is the world’s most scientifically proven and independently tested electrical shark deterrent.

Nothing is more effective.
