Does not attract sharks

Scientific research has proven that Shark Shield Technology does not attract sharks before deterring them

How it works

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

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. As fish are without these receptors, Shark Shield Technology has negligible effect on them.

What people are saying

“I went out for a surf last Saturday morning at a remote beach in the South West of WA when I got charged by a shark. It tried to charge another couple of times but every time it seemed to get turned away by the FREEDOM+ Surf on my board. I'd like to thank Ocean Guardian as this little device probably saved my life.”

ROMAIN, SURFER, AUSTRALIA

“I have owned Ocean Guardian shark deterrents for over 10yrs, from the FREEDOM4 to the FREEDOM7 available today. I have consistently spear fished on the Great Barrier Reef and seen the Shark Shield turn sharks away repeatedly. Bull Sharks, White Tip, Black Tip, Silver Tip, and many other Whaler Sharks over 10 feet and 350KG."
