Product Design + Engineering
Ocean Guardian eSPEAR is the world’s first handheld shark deterrent designed for diving, snorkelling and spearfishing. eSPEAR is a small, lightweight and easy to carry device designed for the everyday ocean user and is powered by Shark Shield Technology, the only scientifically proven and independently tested electrical shark deterrent technology.
Proven shark protection.
eSPEAR is a compact, lightweight handheld baton that more than doubles in length when deployed. It turns on automatically when triggered and retracts when held out of the water. A highly visible LED indicator shows operational status and battery life, while a rubberised handle and finger guard provide a secure grip and reduce the likelihood of the baton being dropped. eSPEAR generates an electrical field over 1 metre high x 2.5 metres wide, offering powerful and proven shark protection.
Share the ocean safely.
Developed over more than 20 years, Ocean Guardian’s patented Shark Shield Technology consists of two electrodes which create a powerful three-dimensional electrical field when submerged. Shark Shield causes sharks to experience safe, but unbearable, spasms in their sensitive electrical receptors, which results in them turning away. eSPEAR allows people to enjoy the ocean safely without causing harm to marine life.
