Shark shield: very useful indeed

South Africans have invented a electromagnetic shield that protects humans from the shark attacks. The idea has already been tested and saved lives.

The technology is based in a three dimensional electrical wave form that induces spasms in the sharks’ snouts, saving surfers and swimmers from severe injuries and deaths.

After the series attacks at the Egyptian Red Sea resort of Sharm el-Sheikh, the local authorities have showed interest in buying devices to protect the tourists.

The shark shield does not interfere with the movement of ships and boats and can be safely used by anyone. There's even a special device for surfers. It's a compact light-weight unit designed specifically to be mounted on watercraft including surfboards and windsurf boards.
