What is a Shark Shield? How does it work?

AAP logoAAP 30/11/2016 Sarah McPhee

WHAT IS A SHARK SHIELD?

* A personal shark protection device and electrical deterrent

* Emits a localised electromagnetic field causing a shark's highly sensitive receptors in its snout (ampullae of Lorenzini) to spasm, turning the animal away

* Models available for surfing, scuba and professional diving, or free-diving and spearfishing ($599-$799)

* Independently tested in South Australian and South African waters

* Non-lethal device with no known long-term adverse effects to sharks

* Little to no impact on surfing performance

* Can be switched between boards or equipment and removed for recharging
