In the early 1990's scientists from the Natal Sharks Board of South Africa discovered a unique electronic wave-form that deterred sharks. The Natal Shark Board is considered one of the world's leading research organisations on predator sharks. After many years of research, this technology was developed and incorporated into a product known at the time as the Shark POD.
The Shark POD proved to be very successful at deterring sharks, however like many new technology innovations it was bulky, heavy and expensive. After a number of years of innovative research, including the filing of numerous patents, the first Shark Shield product range was launched for divers in April 2002.
