Caption: Shark protection device. Diver testing the shark POD (protective oceanic device), a piece of equipment designed to repel shark attacks. The POD fixes to a diver's oxygen tank, with an emitter (yellow) on one of the flippers. It uses electromagnetic signals to confuse and disorientate sharks. Sharks have a highly sophisticated sense that detects the electrical impulses produced by potential prey. The designers of the POD found a frequency and strength which affected this sense, causing distress for some of the more dangerous sharks: great whites, bull and tiger sharks. Photographed off Rangiroa Atoll in French Polynesia.
