Ocean Guardian – eSPEAR

Developed over more than 20 years, Ocean Guardian‘s patented Shark Shield Technology is the world’s only scientifically proven and independently tested shark deterrent technology. Consisting of two electrodes which create a powerful three-dimensional electrical field when submerged, it causes sharks to experience safe, but unbearable, spasms in their sensitive electrical receptors, turning them away. The challenge was to develop a device using Shark Shield Technology that was small enough to be used by everyday ocean users when diving, snorkelling and spearfishing and yet offered a level of protection similar to larger Ocean Guardian devices (developed for surf boards and boats).

Our solution was to develop eSPEAR, a compact, lightweight handheld baton that more than doubles in length when deployed. eSPEAR 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 dropping the baton. The fully encapsulated electronic design guarantees watertightness, and a powerful lithium battery provides 1-2 hours of continuous operation. eSPEAR generates an electrical field over 1 metre high x 2.5 metres wide, offering powerful and proven shark protection.

The fear of shark attack is a growing issue for everyday ocean users, not just for surfers and commercial divers. eSPEAR is the first product to address this concern, using patented technology and innovative design to provide a cost effective way for people to enjoy the ocean safely without causing harm to marine life. Ocean Guardian eSPEAR has the potential to have a significant positive impact on the marine environment by removing the need for harmful shark deterrents. eSPEAR also represents the next step in Ocean Guardian‘s larger ambition to completely replace shark nets and drum lines around the world.
