Shark Shield® Technology

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.

Shark Shield Technology effectively reduces the probability of shark attack


Shark Shield Technology effectively deters white sharks attacking seal decoy


The FREEDOM+ Surf is proven to deter Great Whites


Shark Shield Technology does not attract sharks


Recreational, charter and commercial fishers in Western Australia (WA) are reporting significant increases in shark depredation (bite-offs), particularly in the Gascoyne and Pilbara regions. Recent research by the Department of Primary Industries and Regional Development’s (DPIRD) has found that the probability of sharks taking fish is reduced by 65 per cent when using deterrents such as the FISH01.

Despite the low chance of a person being bitten by a shark, there are serious associated costs. Electronic deterrents are currently the only types of personal deterrent with empirical evidence of a substantial reduction in the probability of being bitten by a shark. We aimed to predict the number of people who could potentially avoid being bitten by sharks in Australia if they wear personal electronic deterrents.
