Would a hungry shark react differently? The research paper involved scientists from UWA, Macquarie University, Flinders University and Oceans Research in South Africa and has been published in PLOS ONE. This suggests it could be an important safety consideration for a range of ocean users such as surfers, divers, spear fishers and open-water swimmers.

Well, you don’t see this every day. The FREEDOM+ Surf significantly affected shark behaviour by reducing the percentage of bait taken from 96% (for the control board) to 40% with sharks remaining further away from the bait when the FREEDOM+ Surf was active. A legacy-defining book from Sir David Attenborough, reflecting on his life's work, the dramatic changes to the planet he has witnessed, and what we can do to make a better future. This new research was undertaken in late 2017 and early 2018 was led by highly regarded Associate Professor Charlie Huveneers of Flinders University, was commissioned by the NSW Department of Primary Industry and resulted in Ocean Guardian’s shark deterrent for surfers being the only device shown to significantly reduce risk.

Test footage with the Shark Shield switched on (left) and turned off (right). We carried out our testing in Mossel Bay, South Africa, in 2014.

But without robust, independent scientific evaluation we can’t be sure which of these products actually work. Keep up to date with our stylish calendars and diaries. In fact, not only may some devices not be as effective as others, but it is also possible that some of them could actually attract sharks rather than repel them. Tiger Shark Encounter – Director's CHOMP! Many have never been tested and a lot of the studies haven’t been robust enough,” he said. However almost none came closer than 0.9m said sensory behaviour expert Prof Shaun Collin. Home News Great white shark deterrent almost 100 per cent effective. There are many shark deterrent devices on the market, particularly those that use electric or magnetic fields. This causes uncomfortable muscle spasms in sharks that swim too close and discourages them from coming into contact.

Upon first encounter with a Shark Shield, all approaching great white sharks were effectively deterred, staying an average of 1.3 metres away from a baited canister with the device attached. A wearable electric shark deterrent can effectively repel great white sharks, according to our independent tests of the device. It’s important to note that the likelihood of being involved in a negative encounter with a shark is exceptionally low. Marine biologists have discovered an enormous great white shark they're calling the "queen of the ocean" off the coast of Nova Scotia..
Only one encounter out of 43 active Shark Shield ™ encounters featured a great white touching the canister after several approaches. Our research, published in the journal PLoS ONE, shows that the device does indeed make sharks keep their distance. Photographer Ethan Mann captured this rakali stealing a fish out of an esky.

Testing of the device was carried in 2014 at a great white shark hotspot, South Africa’s Mossel Bay, by researchers from the University of Western Australia (UWA), Macquarie University, Flinders University and Oceans Research in South Africa. The manufacturers of the AU $749 Shark Shield Freedom 7TM say it works by emitting an electric field around the wearer. Sharks have short-range electrical receptors in their snouts called the “Ampullae of Lorenzini” used for finding food. A fisherman has described the terrifying moment he was stalked by a great white shark off the Esperance coast, just seven miles from where Gary Johnson was mauled to … It was growing rainforests, not humans, scientists say. A 50-year-old, 3,500-pound great white shark spotted off the coast of Nova Scotia is being tracked by research and exploring group Ocearch. Although the effectiveness of the Shark Shield probably varies between shark species, it is encouraging to note its effect on great white sharks, the species implicated in the majority of fatal incidents worldwide. After multiple approaches, individual great white sharks showed signs of habituation to the Shark Shield, coming an average of 12 cm closer on each successive approach. Shark Shield is a personal electronic device that creates an electromagnetic field to deter shark attacks and is used by surfers, scuba divers, spearfishing, and ocean kayak fishing.It has been considered one of the few electrical devices on the market that has performed independent trials to determine the effectiveness at deterring shark attacks. Ocean Guardian’s patented 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. Powered by Shark Shield Technology, the Ocean Guardian FREEDOM7 gives you up to 6-hours protection from all predatory sharks – including Great Whites.
