GW close call while abalone diving off of the California coast

Nearly two weeks ago, I was abalone diving off of the California coast in an area known for Great Whites and attacks. I have had several encounters with GWs in the past so I purchased a Sharkshield and mounted it inside my dive tube with the tail going through a hole in the bottom of the tube. In th... Read more

Ocean Swimmer saved by Shark Shield only weeks following a fatal attack

I'm a regular swimmer at Cottesloe beach in Western Australia. In October of 2011 another regular, Brin Martin, had been killed by a shark. His body was never recovered but from the bite marks on his bathers it was determined to be a white pointer. Needless to say this motivated me to purchase a sha... Read more

Shark Shield is the worlds only scientifically proven and independently tested electronic shark deterrent, and in 2012 Australian scientist's from the South Australian Research and Development Institute (SARDI) independently tested Shark Shield off the coast of South Africa using towed seal decoys, a test that closely resembles a shark in full attack mode, Great White Sharks moving at pace.

With the Shark Shield turned OFF, there were 16 breaches and 27 surface interactions. With the Shark Shield turned ON, there were zero breaches and only 2 surface interactions.

Shark Shield electronic shark deterrents are the result of over twenty years of scientific research and testing by some of the world’s leading experts in sharks, including the KwaZulu-Natal Shark Board in South Africa. Shark Shield is trusted the world over by professional divers in the US and Australian Navies and is mandated safety equipment in many industries such as Professional Abalone Diving.

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 distances 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 attract 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.

Shark Shield is comfortable and lightweight with a low drag antenna trailing behind providing complete freedom to enjoy your free-diving, spearfishing, scuba diving, surfing or kayak fishing. Our rechargeable lithium ion battery provides up to seven hours of use, giving you plenty of time to enjoy the ocean with the confidence of knowing you are protected by Shark Shield.
