STOPPING SHARKS

How does the Ocean Guardian BOAT01 work?

1 Electrodes

Two electrodes are lowered into the water two metres apart. When submerged the electrodes emit an electrical field around the boat.

2 Range

The BOAT01 emits an electrical field in the water of around eight metres deep and six metres wide.

3 Electrical perception

A shark will perceive the perimeter of the electrical field within less than 50 centimetres.

4 Deterrent

The electrical signal emitted from the electrodes causes muscles spasms, thus deterring sharks swimming closer. Ocean Guardian says this is not harmful to the shark in any way.

5 Power module

A lithium battery bobs on the surface of the water, delivering power to the submerged electrodes for around 12 hours.
